Youth Drinking: Risk Factors and Consequences

Despite a minimum legal drinking age of 21, many young people in the United States consume alcohol. Some abuse alcohol by drinking frequently or by binge drinking-often defined as having five or more drinks* in a row. A minority of youth may meet the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for alcohol dependence. The progression of drinking from use to abuse to dependence is associated with biological and psychosocial factors. This Alcohol Alert examines some of these factors that put youth at risk for drinking and for alcohol-related problems and considers some of the consequences of their drinking.

Prevalence of Youth Drinking

Thirteen- to fifteen-year-olds are at high risk to begin drinking. According to results of an annual survey of students in 8th, 10th, and 12th grades, 26 percent of 8th graders, 40 percent of 10th graders, and 51 percent of 12th graders reported drinking alcohol within the past month. Binge drinking at least once during the 2 weeks before the survey was reported by 16 percent of 8th graders, 25 percent of 10th graders, and 30 percent of 12th graders.

Males report higher rates of daily drinking and binge drinking than females, but these differences are diminishing. White students report the highest levels of drinking, blacks report the lowest, and Hispanics fall between the two.

A survey focusing on the alcohol-related problems experienced by 4,390 high school seniors and dropouts found that within the preceding year, approximately 80 percent reported either getting "drunk," binge drinking, or drinking and driving. More than half said that drinking had caused them to feel sick, miss school or work, get arrested, or have a car crash.

Some adolescents who drink later abuse alcohol and may develop alcoholism. Although these conditions are defined for adults in the DSM, research suggests that separate diagnostic criteria may be needed for youth.

Drinking and Adolescent Development

While drinking may be a singular problem behavior for some, research suggests that for others it may be an expression of general adolescent turmoil that includes other problem behaviors and that these behaviors are linked to unconventionality, impulsiveness, and sensation seeking.

Binge drinking, often beginning around age 13, tends to increase during adolescence, peak in young adulthood (ages 18-22), then gradually decrease. In a 1994 national survey, binge drinking was reported by 28 percent of high school seniors, 41 percent of 21- to 22-year-olds, but only 25 percent of 31- to 32-year-olds. Individuals who increase their binge drinking from age 18 to 24 and those who consistently binge drink at least once a week during this period may have problems attaining the goals typical of the transition from adolescence to young adulthood (e.g. marriage, educational attainment, employment, and financial independence).

Risk Factors for Adolescent Alcohol Use, Abuse, and Dependence Genetic

Risk Factors - Animal studies and studies of twins and adoptees demonstrate that genetic factors influence an individual's vulnerability to alcoholism. Children of alcoholics are significantly more likely than children of nonalcoholics to initiate drinking during adolescence and to develop alcoholism, but the relative influences of environment and genetics have not been determined and vary among people.

Biological Markers - Brain waves elicited in response to specific stimuli (e.g. a light or sound) provide measures of brain activity that predict risk for alcoholism. P300, a wave that occurs about 300 milliseconds after a stimulus, is most frequently used in this research. A low P300 amplitude has been demonstrated in individuals with increased risk for alcoholism, especially sons of alcoholic fathers. P300 measures among 36 preadolescent boys were able to predict alcohol and other drug (AOD) use 4 years later, at an average age of 16.

Childhood Behavior - Children classified as "undercontrolled" (i.e. impulsive, restless, and distractible) at age 3 were twice as likely as those who were "inhibited" or "well-adjusted" to be diagnosed with alcohol dependence at age 21. Aggressiveness in children as young as ages 5-10 has been found to predict AOD use in adolescence. Childhood antisocial behavior is associated with alcohol-related problems in adolescence and alcohol abuse or dependence in adulthood.

Psychiatric Disorders - Among 12- to 16-year-olds, regular alcohol use has been significantly associated with conduct disorder; in one study, adolescents who reported higher levels of drinking were more likely to have conduct disorder.

Six-year-old to seventeen-year-old boys with attention deficit hyperactivity disorder (ADHD) who were also found to have weak social relationships had significantly higher rates of alcohol abuse and dependence 4 years later, compared with ADHD boys without social deficiencies and boys without ADHD.

Whether anxiety and depression lead to or are consequences of alcohol abuse is unresolved. In a study of college freshmen, a DSM-III diagnosis of alcohol abuse or dependence was twice as likely among those with anxiety disorder as those without this disorder. In another study, college students diagnosed with alcohol abuse were almost four times as likely as students without alcohol abuse to have a major depressive disorder. In most of these cases, depression preceded alcohol abuse. In a study of adolescents in residential treatment for AOD dependence, 25 percent met the DSM-III-R criteria for depression, three times the rate reported for controls. In 43 percent of these cases, the onset of AOD dependence preceded the depression; in 35 percent, the depression occurred first; and in 22 percent, the disorders occurred simultaneously.

Suicidal Behavior - Alcohol use among adolescents has been associated with considering, planning, attempting, and completing suicide. In one study, 37 percent of eighth-grade females who drank heavily reported attempting suicide, compared with 11 percent who did not drink. Research does not indicate whether drinking causes suicidal behavior, only that the two behaviors are correlated.

Psychosocial Risk Factors - Parenting, Family Environment, and Peers. Parents' drinking behavior and favorable attitudes about drinking have been positively associated with adolescents' initiating and continuing drinking. Early initiation of drinking has been identified as an important risk factor for later alcohol-related problems. Children who were warned about alcohol by their parents and children who reported being closer to their parents were less likely to start drinking.

Lack of parental support, monitoring, and communication have been significantly related to frequency of drinking, heavy drinking, and drunkenness among adolescents. Harsh, inconsistent discipline and hostility or rejection toward children have also been found to significantly predict adolescent drinking and alcohol-related problems.

Peer drinking and peer acceptance of drinking have been associated with adolescent drinking. While both peer influences and parental influences are important, their relative impact on adolescent drinking is unclear.

Expectancies - Positive alcohol-related expectancies have been identified as risk factors for adolescent drinking. Positive expectancies about alcohol have been found to increase with age and to predict the onset of drinking and problem drinking among adolescents.

Trauma - Child abuse and other traumas have been proposed as risk factors for subsequent alcohol problems. Adolescents in treatment for alcohol abuse or dependence reported higher rates of physical abuse, sexual abuse, violent victimization, witnessing violence, and other traumas compared with controls. The adolescents in treatment were at least 6 times more likely than controls to have ever been abused physically and at least 18 times more likely to have ever been abused sexually. In most cases, the physical or sexual abuse preceded the alcohol use. Thirteen percent of the alcohol dependent adolescents had experienced posttraumatic stress disorder, compared with 10 percent of those who abused alcohol and 1 percent of controls.

Advertising - Research on the effects of alcohol advertising on adolescent alcohol-related beliefs and behaviors has been limited. While earlier studies measured the effects of exposure to advertising, more recent research has assessed the effects of alcohol advertising awareness on intentions to drink. In a study of fifth- and sixth-grade students' awareness, measured by the ability to identify products in commercials with the product name blocked out, awareness had a small but statistically significant relationship to positive expectancies about alcohol and to intention to drink as adults. This suggests that alcohol advertising may influence adolescents to be more favorably predisposed to drinking.

Consequences of Adolescent Alcohol Use

Drinking and Driving. Of the nearly 8,000 drivers ages 15-20 involved in fatal crashes in 1995, 20 percent had blood alcohol concentrations above zero. For more information about young drivers' increased crash risk and the factors that contribute to this risk, see Alcohol Alert No. 31: Drinking and Driving.

Sexual Behavior - Surveys of adolescents suggest that alcohol use is associated with risky sexual behavior and increased vulnerability to coercive sexual activity. Among adolescents surveyed in New Zealand, alcohol misuse was significantly associated with unprotected intercourse and sexual activity before age 16. Forty-four percent of sexually active Massachusetts teenagers said they were more likely to have sexual intercourse if they had been drinking, and 17 percent said they were less likely to use condoms after drinking.

Risky Behavior and Victimization - Survey results from a nationally representative sample of 8th and 10th graders indicated that alcohol use was significantly associated with both risky behavior and victimization and that this relationship was strongest among the 8th-grade males, compared with other students.

Puberty and Bone Growth - High doses of alcohol have been found to delay puberty in female and male rats, and large quantities of alcohol consumed by young rats can slow bone growth and result in weaker bones. However, the implications of these findings for young people are not clear.

Prevention of Adolescent Alcohol Use

Measures to prevent adolescent alcohol use include policy interventions and community and educational programs. Alcohol Alert No. 34: Preventing Alcohol Abuse and Related Problems covers these topics in detail. See the National Institute on Alcohol Abuse and Alcoholism's (NIAAA's) World Wide Web site at hhttp://www.niaaa.nih.gov.

*A standard drink is 12 grams of pure alcohol, which is equal to one 12-ounce bottle of beer or wine cooler, one 5-ounce glass of wine, or 1.5 ounces of 80-proof distilled spirits.

Out of State Drivers arrested in Texas for DWI

How Would a Conviction be treated by my "Home State"

If you are convicted in Texas, you may lose only your driving privileges in the state of Texas. However, Texas will report your conviction to your home state, and your home state will, in all likelihood, suspend your license for whatever period someone in your state would get if he/she were convicted in your state for DWI/DUI.

The Drivers License Compact require member states to report tickets received by motorist to the state where they received a license to drive so as to receive points and get an insurance hike. Also when a state suspends the license of a driver who is from out-of-state, the state where the motorist received a license to drive will also suspend their license. Texas is a member of the Compact, and will report any infractions to your "home state".

The only states that are not members are: Tennessee, Georgia, Massachusetts, Wisconsin and Michigan. However, Georgia, Michigan, Wisconsin will report tickets to your home state even though they are not members of the compact.

How other States treat Out of State matters

Colorado, Ohio, and Wisconsin do not assess points for out-of-state convictions. Colorado does not make an entry for out-of-state convictions such as speeding but convictions for offenses like DUI still count! Colorado will issue you a license if you qualify. New York, same rules apply as for Colorado except New York does apply points for moving violations in Ontario and Quebec. Michigan and Georgia will assess points for out-of-state tickets. Kentucky does not assess points for out-of-state speeding tickets but will for others. Vermont and North Carolina do not report tickets to your home state unless violation results in license suspension. North Carolina will not assess points for out-of-state tickets unless the violation, if committed in North Carolina would result in a suspension. Kansas, Wyoming, Minnesota, Arizona, Iowa, and South Dakota will not put speeding tickets on record unless it is 10 or more mph over the limit. If the violation was committed by an out-of-state motorist, the violation may still be reported to the home state which can result in points being assessed. South Dakota will not assess points for speeding tickets. This may change since the repeal of the 55 mph National Speed Limit.

About the Non-Resident Violator Compact

The Non-Resident Violator Compact requires member states to suspend the drivers license of those who get traffic tickets for moving violations in other states and fail to pay them. The compact is not supposed to include non-moving violations such as expired inspection stickers, equipment violations such as window tinting or parking violations. A member state may choose to voluntarily suspend a license of a person who does not pay an out-of-state ticket for an equipment violation such as loud exhaust.

Blood Alcohol Content

Blood alcohol content or blood alcohol concentration (abbreviated BAC) is the concentration of alcohol in a person's blood. BAC is most commonly used as a metric of intoxication for legal or medical purposes. It is usually measured in terms of mass per volume, but can also be measured in terms of mass per mass. Blood alcohol concentration is given in many different units and notations, but they are all relatively synonymous with each other numerically.

The number of drinks consumed is a poor measure of BAC, largely because of variations in weight, sex, and body fat. However, it is generally accepted that the consumption from sober of one standard drink of alcohol (e.g. 14 grams (17.74 ml) ethanol content by U.S. standard) will increase the average person's BAC roughly 0.02% to 0.05% and would return to 0% about 1.5 to 3 hours later (at a dissipation rate of around 0.015% per hour).

Effects of Alcohol at Different Levels

Unless a person has developed a high tolerance for alcohol, a BAC rating of 0.20% represents very serious intoxication (most first-time drinkers would be unconscious by about 0.15%), and 0.35%–0.40% represents potentially fatal alcohol poisoning. 0.40% is the accepted LD50, the dose that is lethal for 50% of adult humans. However, there have been cases of people surviving and even remaining conscious at BACs above 0.40%.





Units of measurement

There are several different units in use around the world for defining blood alcohol concentration. Each is defined as either a mass of alcohol per volume of blood or a mass of alcohol per mass of blood (never a volume per volume). 1 milliliter of blood is approximately equivalent to 1 gram of blood, 1.06 grams to be exact. Because of this, units by volume are similar but not identical to units by mass.



Legal limits

For purposes of law enforcement, BAC is used to define intoxication and provides a rough measure of impairment. Although degree of impairment may vary among individuals with the same BAC, BAC can be measured objectively and is therefore legally useful and difficult to contest in court. Most countries disallow operation of motor vehicles and heavy machinery above prescribed levels of BAC. Operation of boats and aircraft are also regulated.

The alcohol level at which a person is considered to be legally impaired varies by country. The list below gives limits by country. These are typically BAC (blood alcohol content) limits for the operation of a vehicle.
0.00% - Czech Republic, Hungary, Romania, Saudi Arabia, Slovakia, United Arab Emirates
0.02% - Brazil, Estonia, Poland, Sweden, Norway
0.03% - India (note: In the State of Kerala, since of late, it is illegal to even have a sip and drive)[8], Japan[9], Russia
0.04% - Lithuania
0.05% - Argentina (0.02% for motorbikes, 0.00% for truck/taxi/bus drivers), Australia (0.02% for Australian Capital Territory learner, probationary & convicted DUI drivers, 0.00% for learner drivers, provisional/probationary drivers (regardless of age) and DUI drivers), Austria, Belgium, British Columbia, Manitoba (0.05% is a 24-hour suspension and a fine, 0.08% is a D.U.I. charge)(0.00% for drivers with class G1 or G2 licenses in Ontario, or class 7 or 5P in the Northwest Territories, or drivers with a under the Graduated License System in Manitoba, and Alberta, or class 7 or 7L in British Columbia), Bulgaria, Costa Rica, Croatia, Denmark, Finland, France, Germany (0.00% for learner drivers, all drivers 18-21 and newly licensed drivers of any age for first two years of licence), Greece, Iceland, Israel, Italy, Latvia, Luxembourg, Netherlands (0.02% for drivers in their first five years after gaining a driving license), Portugal, Republic of Macedonia, Serbia, Slovenia (0.00% for drivers in their first two years after gaining a drivers licence), South Africa, Spain (0.015% for drivers in their first two years after gaining a driving licence), Switzerland, Thailand, Turkey
0.08% - Canada, Malaysia, Malta, Mexico, New Zealand (0.03% for drivers under 20), Ireland, Singapore, United Kingdom (0.02% for operators of aeroplanes), United States

For further information on U.S. laws, see Alcohol laws of the United States by state (0.01% for operators of common carriers, such as buses, 0.04% for pilots, Federal Aviation Regulations within eight hours of consumption).

Test assumptions

Blood alcohol tests assume the individual being tested is average in various ways. For example, on average the ratio of BAC to breath alcohol content (the partition ratio) is 2100 to 1. In other words, there are 2100 parts of alcohol in the blood for every part in the breath. However, the actual ratio in any given individual can vary from 1300:1 to 3100:1, or even more widely. This ratio varies not only from person to person, but within one person from moment to moment. Thus a person with a true blood alcohol level of .08 but a partition ratio of 1700:1 at the time of testing would have a .10 reading on a Breathalyzer calibrated for the average 2100:1 ratio.

A similar assumption is made in urinalysis. When urine is analyzed for alcohol, the assumption is that there are 1.3 parts of alcohol in the urine for every 1 part in the blood, even though the actual ratio can vary greatly.

Breath alcohol testing further assumes that the test is post-absorptive—that is, that the absorption of alcohol in the subject's body is complete. If the subject is still actively absorbing alcohol, his body has not reached a state of equilibrium where the concentration of alcohol is uniform throughout the body. Most forensic alcohol experts reject test results during this period as the amounts of alcohol in the breath will not accurately reflect a true concentration in the blood.

Metabolism and excretion

Alcohol is removed from the bloodstream by a combination of metabolism, excretion, and evaporation. The relative proportion disposed of in each way varies from person to person, but typically about 92 to 98% is metabolised, 1 to 3% is excreted in urine, and 1 to 5% evaporates through the breath. A very small proportion (less than 0.5%) is also excreted in the sweat, tears, etc. Excretion into urine typically begins after about 40 minutes, whereas metabolisation commences as soon as the alcohol is absorbed, and even before alcohol levels have risen in the brain. (In fact, in some males, alcohol dehydrogenase levels in the stomach are high enough that some metabolization occurs even before the alcohol is absorbed.)

Alcohol is metabolised mainly by the group of six enzymes collectively called alcohol dehydrogenase. These convert the ethanol into acetaldehyde (an intermediate that is actually more toxic than ethanol). The enzyme acetaldehyde dehydrogenase then converts the acetaldehyde into non-toxic Acetyl-CoA.

Many physiologically active materials are removed from the bloodstream (whether by metabolism or excretion) at a rate proportional to the current concentration, so that they exhibit exponential decay with a characteristic halflife (see pharmacokinetics). This is not true for alcohol, however. Typical doses of alcohol actually saturate the enzymes' capacity, so that alcohol is removed from the bloodstream at an approximately constant rate. This rate varies considerably between individuals; experienced male drinkers with a high body mass may process up to 30 grams (38 mL) per hour, but a more typical figure is 10 grams (12.7 mL) per hour. Persons below the age of 25, women, persons of certain ethnicities, and persons with liver disease may process alcohol more slowly. Many East Asians (e.g. about half of Japanese) have impaired acetaldehyde dehydrogenase; this causes acetaldehyde levels to peak higher, producing more severe hangovers and other effects such as flushing and tachycardia. Conversely, members of certain ethnicities that traditionally did not brew alcoholic beverages have lower levels of alcohol dehydrogenases and thus "sober up" very slowly, but reach lower aldehyde concentrations and have milder hangovers. Rate of detoxification of alcohol can also be slowed by certain drugs which interfere with the action of alcohol dehydrogenases, notably aspirin, furfural (which may be found in fusel oil), fumes of certain solvents, many heavy metals, and some pyrazole compounds. Also suspected of having this effect are cimetidine (Tagamet), ranitidine (Zantac), and acetaminophen (Tylenol) (paracetamol).

Currently, the only known substance that can increase the rate of metabolism of alcohol is fructose. The effect can vary significantly from person to person, but a 100g dose of fructose has been shown to increase alcohol metabolism by an average of 80%.

Alcohol ingestion can be slowed by ingesting alcohol on a full stomach. Spreading the total absorption of alcohol over a greater period of time decreases the maximum alcohol level, decreasing the hangover effect. Thus, drinking on a full stomach or drinking while ingesting drugs which slow the release of acetaldehyde, will reduce the maximum blood levels of this substance, and decrease the hangover. Alcohol in non-carbonated beverages is absorbed more slowly than alcohol in carbonated drinks.

Retrograde extrapolation

Retrograde extrapolation is the mathematical process by which someone's blood alcohol concentration at the time of driving is estimated by projecting backwards from a later chemical test. This involves estimating the absorption and elimination of alcohol in the interim between driving and testing. The rate of elimination in the average person is commonly estimated at .015 to .020 percent per hour, although again this can vary from person to person and in a given person from one moment to another. Metabolism can be affected by numerous factors, including such things as body temperature, the type of alcoholic beverage consumed, and the amount and type of food consumed.

In an increasing number of states, laws have been enacted to facilitate this speculative task: the BAC at the time of driving is legally presumed to be the same as when later tested. There are usually time limits put on this presumption, commonly two or three hours, and the defendant is permitted to offer evidence to rebut this presumption.

Forward extrapolation can also be attempted. If the amount of alcohol consumed is known, along with such variables as the weight and sex of the subject and period and rate of consumption, the blood alcohol level can be estimated by extrapolating forward. Although subject to the same infirmities as retrograde extrapolation—guessing based upon averages and unknown variables—this can be relevant in estimating BAC when driving and/or corroborating or contradicting the results of a later chemical test.

Blood alcohol content calculation

BAC can be roughly estimated using a mathematical approach. While a mathematical BAC estimation is not as accurate as a breathalyzer, it can be useful for calculating a BAC level that is not currently testable, or a level that may be present in the future. While there are several ways to calculate a BAC, one of the most effective ways is to simply measure the total amount of alcohol consumed divided by the total amount of water in the body—effectively giving the percent alcohol per volume water in the blood.

The total water weight of an individual can be calculated by multiplying his or her body weight by their percent water. For example, a 150 pound woman would have a total amount of water of 73.5 pounds (150 x .49). For easiest calculations, this weight should be in kilograms, which can be easily converted by dividing the total pounds by 2.205. 73.5 pounds of water is equivalent to 33.3 kilograms of water. 33.3 kilograms of water is equivalent to 33,300 mL of water (1 L of water has a mass of 1 kg, and 1 L = 1000 mL).

Gender plays an important role in the total amount of water that a person has. In general, men have a higher percent of water per pound (58%) than women (49%). This fact alone strongly contributes to the generalization that men require more alcohol than women to achieve the same BAC level. Additionally, men are, on average, heavier than women. The more water a person has, the more alcohol is required to achieve the same alcohol:blood ratio, or BAC level. Further, studies have shown that women's alcohol metabolism varies from that of men due to such biochemical factors as different levels of alcohol dehydrogenase (the enzyme which breaks down alcohol) and the effects of oral contraceptives.

It is not strictly accurate to say that the water content of a person alone is responsible for the dissolution of alcohol within the body, because alcohol does dissolve in fatty tissue as well. When it does, a certain amount of alcohol is temporarily taken out of the blood and briefly stored in the fat. For this reason, most calculations of alcohol to body mass simply use the weight of the individual, and not specifically his water content.

10 Mistakes Lawyers Make In DWI Cases And How To Avoid Them

Even though attorneys are schooled in the laws pertaining to a wide variety of legal areas, a huge amount of expertise comes from practical experience, either by prosecuting or defending individuals or businesses. For DWI cases, which involve a great deal of science in addition to just knowledge of the basic governing laws, this experience may be the most critical thing.

And because of the complexity of DWI cases, knowledgeable attorneys consider them to be among the most difficult to defend. Because of this same complexity, a great many attorneys make 10 big mistakes when it comes to defending DWI clients, mistakes which can profoundly harm their clients in terms of losing their license, paying considerable fines, being jailed, having huge increases in their insurance rates, and the effect it could have on their current or future job. To protect yourself and to help decide whom to hire and how to plead, you had better know what these mistakes are.

1. Assuming the Case Can’t be Won

Making this assumption and pleading you guilty is the single most important mistake attorneys make in representing individuals arrested for DWI. After getting the breath test result and the police report, many lawyers simply give it up and advise the client to plead guilty. In fact, the breath test, the alcohol blood level test, and the roadside tests the arrested person has to perform all have potential built-in flaws: flaws which can make the difference. For example, the results of a breath test can be challenged through a Motion to Suppress, or evidence of your sobriety, or with cross examination of the police officer or the state’s expert. Records of the specific Intoxilyzer that you used should be examined.

2. Assuming That The Breath Test Rules Were Followed

Virtually every state has rules and regulations concerning the breath test given to people suspected of DWI. The critical point for the prosecution is that these rules must be followed. This leaves open attacking the results on the grounds that the technical rules weren’t followed. Far too many lawyers don’t understand or know the regulations covering breath testing. Those that don’t know the regulations don’t realize that violations of the rules introduced into evidence, and other things that aren't introduced into evidence, can show that the results are unreliable. Further, showing this can be used to exclude the breath test results altogether. Here’s an example. The officer is supposed to observe you for 15 minutes before giving the test to make sure you don’t hiccup, burp, or puke, because these things can totally skew the test results. Odds are the officer wouldn’t have noticed if you had hiccupped, burped or puked.

In fact, a host of criteria must be met or the test results will often be thrown out. These include:

- the test operator having a current certification.
- the machine having a current certification.
- calibrating the machine as often as required.
- changing the mouthpiece before the test is given.
- keeping a record of the temperature of the calibrating solutions in the machine.
- keeping a log of the tests run.
- counting the number of times the calibration solution has been changed.
- the sample was not taken within a reasonable time of your arrest.
- there is only one test taken.
- the results of the two tests are no more than 0.02 apart
- you have dentures
- you work with solvents

Thus, to defend you properly, a lawyer should get copies of the various logs, maintenance records, and the operator’s license or certification.

3. Not Filing A Motion to Suppress

Not filing this pre-trial motion before a trial is a huge mistake according to many experts, and maybe the most common mistake according to others. Even though this motion doesn’t succeed very often, a case can be won by filing it. While a stop is generally justified if you were weaving from lane to lane, weaving within a lane may not make the stop justified. And whether they’ll admit it or not, this motion may resonate with a judge. Equally as important, even if the motion loses, it provides another opportunity to question the arresting officer. The officer can be asked broad range of questions. And his testimony can be used at trial. If the testimony at the pre-trial hearing is different from that at the trial, the stronger your case is. And it is not uncommon for this to happen.

4. Not Personally Checking Out The Arrest Location

Many lawyers don’t visit the arrest location. And in some cases, this can be exceedingly crucial. One lawyer goes to the arrest scene even before a prospective client comes in for his/her first appointment. And he takes pictures of the spot where the tests were given. This could point out that the particular location made the roadside test difficult to perform. For example, if there’s heavy traffic speeding by on a highway. Or if the shoulder of the road used for the roadside test is slanted. A slanting road automatically makes the tests more difficult to perform. Or a winding road could explain erratic driving. Seeing and knowing these things makes it much easier for your lawyer to ask probing questions about the roadside test, and, in some cases, point out a physical impossibility to the court. An example: An officer may testify that you wove a certain number of times on the road. But there may not have been enough time for you to weave this many times in a given stretch of road. When illustrated by your attorney, this is very telling. Or, there may have been obstacles preventing you from driving with two wheels on the sidewalk, which the police may claim you did.

5. Not Exploiting The Advantage of The "Training Manual" For Roadside Tests

The "Training Manual" is another example of rules that the police must follow when they perform a field sobriety test, that is, the roadside tests mentioned above. Most lawyers know little about this manual and its rules. A very few actually take training courses themselves to become certified and qualified to give these tests. At the very least, this manual should be studied by your lawyer. He or she will then know exactly what questions to ask the arresting officer to see if he completely followed the manual’s directions. This can be powerful evidence frequently overlooked by defense lawyers. If the manual’s directions weren’t completely followed, the test’s validity can be attacked. At what point the test is attacked varies by state. Wherever your lawyer does it, a successful challenge results in the test evidence being excluded at trial. Which significantly weakens the prosecutor's case. I’ve found that in an extremely large number of cases, the police do things inconsistent with the manual’s material. Even more important, officers don’t always use objective scoring. The manual explains how to score the tests and how to arrive at a final score. All too often the officer simply subjectively decides whether or not you failed the tests. Another facet of this is officers asking you to do more than the manual requires. If you were asked to take a test not in the manual (and there are only three), then your lawyer can challenge the test as not being scientifically validated. Incidentally, the police commonly use tests that aren’t in the manual.

6. Not Explaining The Extra Penalties Coming With a Conviction or a Guilty Plea

Your lawyer must advise you about the administrative sanctions resulting from a conviction. They can include license suspension or revocation, jail time, a significant fine, inability to rent a car, substantially higher insurance rates, and loss of your job (particularly if your job involves driving). You must take these extra penalties into account when deciding to plead guilty. If you’re not aware of these penalties, you cannot help but be the loser.

7. Putting the Client on The Stand

Contrary to popular belief, it is not typically a good idea to put the defendant on the stand, expert DWI attorneys believe. This is primarily because they are not experienced witnesses, often appearing to be nervous. Moreover, a defendant who is put on the stand shifts the judge’s focus. The objective of the defense is to show that the prosecutor’s case is not strong enough to convict beyond all reasonable doubt. When the defendant is put on the stand, however, the focus shifts to the credibility and honesty of the defendant. The judge is thus forced to choose between the police officer and the defendant. Plus, it gives the prosecutor the chance to make the defendant look like he’s hiding something. Only good time to put the defendant on the stand is if attorney needs to contradict something the officer said, beyond that, your lawyer should stick to placing reasonable doubt in the judge’s mind.

8. Attempting to Show The Officer Lied

Your lawyer doesn’t need to make the officer sound like he lied to put reasonable doubt in the judge’s mind. All he really needs to do is show how the officer might simply be mistaken this time. No one wants to believe that the officer is lying. But the Court may accept the officer being mistaken. It’s far better to simply paint the case as being about a cop jumping to conclusions and making mistakes.

9. Not Consulting A Lawyer That Focuses His Practice On DWIs

Just as you wouldn’t hire a criminal attorney to advise on business law or divorce, you should consult with an attorney who handles DWI matters and is fully familiar with the process that goes with it. The reason for this is simple: DWI law is complex, it involves a lot of science, and a generalist cannot be everything to everybody. Knowing how to defend a DWI case involves considerable preparation, familiarity with the law, and knowing what motions to make and when. An attorney that concentrates in DWI law has that knowledge. He or she will quickly be able to spot potential defenses. He’ll know what the investigation and discovery should be.
If your lawyer’s practice is not totally focused on DWIs, you may not be getting the best advice and you may not have the strongest case. DWI is no longer a minor offense. The reforms of the 80's and 90's, the tightening of the standards defining what DWI is, and the penalties imposed have made these cases not just complex, but also important. So it’s necessary for you to hire the best attorney you can afford so your case is as strong as possible.

10. Not Consulting with an Expert on the Testing Procedures

Whether it is a breath test or a blood sample, a serious mistake results when counsel does not consult with the proper experts that can assist in the defense of the case. If the police reports and testing reports are defective, expert testimony is required to prove your case. Consulting with the proper experts, and getting written opinions from those experts when necessary can help convince the Prosecutor that he or she cannot prove your case beyond a reasonable doubt.

10 Biggest Mistakes People Make After Being Arrested For DWI And How To Avoid Them

1. Not taking the matter seriously. This is a charge that will follow you for the rest of your life, if you are convicted. The additional insurance charges alone could cost you thousands of dollars.

2. Not hiring an attorney. The law is complex and you need competent representation. You must raise the right defenses at the right time or you will lose them. Facts will disappear, memories fade and witnesses vanish. A winable case can quickly become a loser.

3. Hiring an attorney based on the amount of the fee alone. The State of Texas has almost unlimited resources when it comes to your case. You need to hire an attorney and pay a fee which will allow him to put time and effort into your case to counter the prosecution. Attorneys must earn enough in the time they spend on your case in order to keep their doors open and make a living wage. If you go too low, your attorney will not be able to put in the time necessary to protect you. Look for a reasonable, predictable fee, not the lowest.

4. Not complying with driver's license laws. You could lose your right to drive.

5. Driving after your license has been taken away.

6. Not taking full advantage of your constitutional rights.

7. Taking the prosecutor's first offer. The first offer is not a bargain, it's just to get rid of your case with the least amount of work. Very few cases are dismissed or reduced to a non-alcohol charge at this stage. You do not give the judge an opportunity to rule on constitutional challenges. You give up your right to raise these issues and make the State prove it's case.

8. Fail to appear in Court. The Court will issue a bench warrant for your arrest and revoke any bond. The next time you are stopped for a traffic infraction, you will be spending some time in jail and posting a bond for your future appearances.

9. Talk to anyone but an attorney about your case. Anything you say to them can be used against you.

10. Think that talking to numerous attorneys will help you handle it on your own. You need to have an attorney go to Court with you.

15 Mistakes The Police Make And How They Can Help You

1. Stopping a vehicle on the basis of an anonymous call. An officer can not rely on a phone call to stop you, if he does not have a name and address for the caller.

2. Following a driver into his residence without an invitaion or without enough information to justify the entry. Your home is protected under the fourth amendment.

3. Basing an arrest on the statements of the driver alone. The officer must have independent evidence to corroborate these statements. This often arises when he has not seen you in physical control of your car.

4. Detaining a driver longer than is reasonable to investigate. The constitution does not allow officers to hold you without limit.

5. Stopping a vehicle without an articulable suspicion. An officer can not stop you just because he thinks you are suspicious.

6. Stopping a vehicle because it stops in the middle of the street or it is driving too slow. Unless there is a specific traffic ordinance you are violating, such as impeding traffic, it is not lawful for an officer to stop you.

7. Weaving within a lane. The statute only requires you to drive as nearly as is practible within a single lane. Some cases hold that one weave into the shoulder is not enough reason for a stop.

8. Stopping a vehicle based on a misperceived violation of a law. The officer must be right about his interpretation of the law.

9. Stopping a vehicle for an improper sign. Street signs and lane markings must comply with Texas law.

10. Failing to follow the rules of the Department of Public Safety, Breath Testing Manual. These failures may invalidate any alcohol testing.

11. Stopping at an improper roadblock. There are guidlines that must be followed to validate the stop.

12. Stopping a vehicle just to check the driver's license and registration. There must be an actual traffic violation or an articulable suspicion of a crime.

13. Stopping a vehicle without being able to identify it as the one actually commiting a traffic infraction. Officers must be able to convince the Court that they stopped the right car.

14. Stopping a vehicle for no reason at all. It's done. Officers usually do not show up in Court on these.

15. Blocking a vehicle's exit without justification. Officers may not restrict a drivers freedom to leave without a reason.

Challenging the Breath Test in Court

A breathalyzer or breath test result showing a blood alcohol concentration (BAC) over the legal limit can be one of the most damaging pieces of evidence in the context of a driving while intoxicated (DWI) or driving under the influence (DUI) trial. Though damaging, however, breathalyzer evidence is not ironclad. A variety of factors may cause false or inaccurate readings, allowing DWI defense lawyers to challenge their reliability in court.

Common ways to dispute breathalyzer test results include:

Calibration Error

Like any machine, breathalyzers degrade and become less sensitive over time. Proper calibration is needed to ensure that results are accurate. Evidence that a machine was not properly adjusted and/or maintained may discredit its results.

Operator Qualifications

In most states, strict laws are in place to regulate the operation and maintenance of breath test machines. Because these devices are very sensitive, operators must be properly trained to adapt to different environmental, biological, and physical circumstances. A test administered by an untrained police officer may produce inaccurate or unreliable readings.

Absorption Defense

The absorption of alcohol into the bloodstream takes time. By some estimates, it may take up to two hours for consumed alcohol to reach equilibrium distribution throughout the body. Breathalyzer tests administered during this period can produce inaccurate results, since alcohol content is inconsistent in different areas of the body. Furthermore, if alcohol has not yet been absorbed into the bloodstream, it does not contribute to a person's level of intoxication.

Biological Variables

Breath test results are based on a standard mathematical formula which relates the amount of alcohol on a person's breath with the amount of alcohol present in their bloodstream. This formula, however, only applies when all biological variables conform to its standards. The ratio of breath alcohol to blood alcohol varies between individuals and over time; variations in body temperature can also affect results.

Summary

All in all, there are many ways in which breathalyzer tests can produce inaccurate or misleading results, leading to situations where defendants can and should challenge this evidence in court.

Drinking Problems and DWI Convictions

It is difficult for many of us to understand why anyone would operate a vehicle while drunk or under the influence of another drug. It is even more perplexing to learn that someone we know has been convicted of this crime multiple times. It seems like a matter of simple common sense to take a taxi or get a ride with a friend when one is impaired. Why do some people have difficulty doing this? There are many potential reasons, ranging from ignorance to recklessness to self-destructive impulses. One common factor among people with DWI convictions is a problem with drinking.

"Alcoholism" has been defined many different ways by many different individuals and organizations, depending on their personal views and experiences. The DSM IV-TR, the current manual that US psychologists use when making diagnoses, attempts to quantify mental health issues by defining them in terms of observable, measurable behaviors. Based on the information they have gathered, the authors of the DSM IV-TR offer two related but distinct drinking problems: abuse and dependency.

Alcohol abuse is the more mild of the two, although it can still have very serious consequences. A person is abusing alcohol if they continue to drink to excess after suffering some sort of consequence for it. The consequence(s) may be legal, such as a DWI conviction; emotional, such as loss of self-respect or damaged relationships with other people; financial, such as spending too much money on liquor or legal fees; or health-related, such as liver damage. A person who is abusing alcohol will not suffer physical symptoms of withdrawal when they cannot drink; they simply have no desire to quit. This may be because alcohol is a way for them to self-medicate a separate emotional problem, such as depression or anxiety. It may be that they feel alcohol gives them something they are lacking in their life, such as self confidence, a sense of security or happiness.

Alcohol dependence is similar to alcohol abuse, with one crucial addition: physiological symptoms. This can mean increased tolerance, requiring the person to drink more to get the same effects, or physical withdrawal. Symptoms of alcohol withdrawal include shakiness, anxiety or irritability, nausea and difficulty concentrating, among others. In the most severe cases, a person might experience what is known as the DT's - a period of intense distress and visual hallucinations.

These difficult emotional problems can make it difficult for a person to resist the temptation to drink at social events, and increase their temptation to drink alone, making it harder to simply get a ride home with a friend. The emotional effects of a drinking problem, such as depression and low self-esteem, also make people more likely to engage in risky behavior.

Drunk Driving Statistics - Fact Or Fiction?

Every 30 minutes, another person is killed by a drunk driver - so says one set of dramatic statistics often cited by anti-alcohol activist groups like Mothers Against Drunk Driving (MADD). No doubt such a statistic should and does make an impact on anyone who hears it. Drunk driving is not a laughing matter, and it is most definitely a serious issue - however, the situation may not be nearly as grim as some make it out to be.

There's a saying that 90% of all statistics can be made to say anything, 50% of the time. While this statement is obviously an exaggeration, it contains a grain of truth - statistics are not nearly as scientifically sound as many people would like to believe. In many cases, statistics become skewed (whether intentionally or unintentionally) and communicate a message inconsistent with the reality they are meant to depict. Could something like this happen in DWI-related research?

Alcohol-Related Incidents

If you believe the popular media, about 50% of all traffic fatalities are caused by the actions of people driving drunk. If you choose to find the truth yourself, you'll probably come up with a percentage closer to 10%, according to the National Motorists Association - a significant drop, to say the least.

Why is the popularized figure so far off? One cause is an unfortunate confusion involving the term "alcohol-related incident." In most cases, any traffic fatality in which someone involved has a measurable amount of alcohol in their system qualifies as an "alcohol-related incident."

This applies even if the person with alcohol in their system was not physically or mentally impaired by alcohol in anyway, if he or she was not the cause of the accident, or even if he or she was an innocent pedestrian who was not behind the wheel at all. That is to say, if a sober driver is driving recklessly and kills a non-impaired pedestrian with a blood alcohol concentration (BAC) of .01 (the legal limit is .08, for comparison), the incident will be classified as alcohol-related and spread over the media by special interest groups and politicians.

Politicization of the Issue

Unfortunately, efforts to actually deter drunk driving have been hindered by the sensationalist approach of the popular media, the single-minded crusade of biased interest groups, and the general politicization of the topic. Because dire DWI statistics make good news, promote interest groups' narrow-minded agendas, and make for dramatic political speeches, they are often preferred in place of the truth.

Although the original goal of organizations like MADD (that is, the goal of preventing drunk driving) is a noble one, this goal has been perverted, becoming more about highly visible and politically attractive actions (sobriety roadblocks and checkpoints, for example) than about solutions which have been scientifically proven to work.

DWI - Texas Law

The state of Texas has a .08 blood alcohol concentration limit for intoxication. However, a driver may be issued a citation for impaired driving due to alcohol or drugs regardless of the amount of alcohol. Impairment can begin with the first drink. Depending on body weight, gender, and the food in one's stomach, a person's tolerance varies. In general, women, smaller people, and younger people do not have high tolerances.

Once you are stopped, you will be asked to take a blood or breath test. You can deny. However, you will then be automatically subjected to a 180 day driver's license. In the state of Texas, punishment for DWI depends on the number of previous convictions.

For a person's first DWI offense, they will spend between 72 hours and 180 days in jail. In addition, they are subject to fines up to $2,000 and their driver's license will be suspended for a minimum of 90 days and a maximum of a year. A second offense carries a possible fine of $4,000. An offender will spend between a month and a year in jail. Their driver's license will be suspended for a maximum of 2 years. If a person is convicted of DWI the third time, they face up to 10 years in prison, a $4,000 fine, and a driver's license suspension for up to 2 years.

If you are found in possession of alcohol and are under 21, the following will occur on the first offense: 30 day driver's license suspension, 8 to 12 hours of community service, alcohol-awareness classes and a fine of up to $500. If a second or third offense occurs, the driver's license can be suspended 180 days. If the offender is above the age of 17 they face a maximum of $2,000 in fines and 180 days in jail for the third offense.

If you are under the legal drinking age of 21 and are drinking and driving, the following will occur: 60 day driver's license suspension, $500 fine, 20 to 40 hours of community service, an alcohol awareness classes. Penalties increase with subsequent offenses.

The state of Texas has a zero tolerance rule. That means an individual under the age of 21 cannot possess any alcohol in their blood. The above consequences will occur if the amount of alcohol is very minimal. If the BAC is .08 or greater and the individual is 17 they face up to 180 days in jail.

DWI - Typical Investigation and Arrest

Following are common procedures when a law enforcement officer has reason to suspect a driver is intoxicated.

Reasonable Suspicion to stop

There are several situations in which the officer will come into contact with a driver, some examples are:
- The driver has been involved in an automobile accident, the officer has responded to the scene and is conducting an investigation.
- The driver has been stopped at a sobriety checkpoint (also known as roadblocks).
- The police have received a report, possibly from an anonymous citizen, that a described car has been driving erratically. The officer should verify the erratic driving before pulling the driver over. In some cases, the driver will no longer be in the vehicle.
- The officer on patrol has observed erratic, suspicious driving, or a series of traffic infractions indicating the possibility that the driver may be impaired. This is by far the most common reason for stopping a suspect.
A police officer has stopped a vehicle for a lesser traffic offense, notices the signs of intoxication, and begins the DWI investigation.

The following list of DWI symptoms, from a publication issued by the National Highway Traffic Safety Administration (DOT HS-805-711) is widely used in training officers to detect drunk drivers. After each symptom is a percentage figure which, according to NHTSA, indicates the statistical chances through research, that a driver is over the legal limit.



f the officer observes enough to have a reasonable suspicion to legally justify a further detention and investigation, he will ask the driver to step out of the vehicle.

Reasonable suspicion requires less evidence than probable cause, but more than a mere hunch. A rule of thumb is that reasonable suspicion requires 25 % proof, and probable cause requires more than 50 % statistical chance. Therefore, if there is probable cause for arrest for DWI, as suggested by the research and examples used above, then there is reasonable suspicion to stop a driver.

Investigation

The officer will typically approach the driver's window and ask some preliminary questions. During this phase of the stop the officer will note if they detect any of the following indicators of intoxication:

- odor of an alcoholic beverage on the driver's breath or in the car generally
slurred speech in response to the questioning
- watery, blood shot, and/or reddish eyes
- flushed face
- droopy eyelids
- difficulty in understanding and responding intelligently to question
- fumbling with his or her driver's license and registration
- the plain-view presence of containers of alcoholic beverages in the vehicle
- admission of consumption of alcoholic beverage

If the officer observes enough to have a reasonable suspicion to legally justify a further detention and investigation, he will ask the driver to step out of the vehicle. In some states (Texas and Louisiana, for example), if the officer has reasonable suspicion or probable cause to make the stop, the driver can be ordered out of the vehicle at any time, not just during a DWI investigation.

Field sobriety tests

The officer will administer one or more field sobriety tests (FSTs). FSTs are "divided attention tests" that theoretically test the suspect's ability to perform the type of mental and physical multitasking that is required to operate an automobile. The most commonly administered FSTs include:
- horizontal gaze nystagmus test, which involves following an object with the eyes (such as a pen) to determine characteristic eye movement reaction. A sober person should be able to smoothly track the object with their eyes. In an intoxicated individual the eyes will jerk as they follow the object
- walk-and-turn (heel-to-toe in a straight line)
- one-leg-stand
- modified-position-of-attention (feet together, head back, eyes closed for thirty seconds; also known as the Romberg test)
- finger-to-nose (tip head back, eyes closed, touch the tip of nose with tip of index finger)
- recite all or part of the alphabet (a common myth is that the alphabet must be recited backwards, however, this is never done during an FST, as many sober people are unable to do this)
- touch each finger of hand to thumb counting with each touch (1, 2, 3, 4, 4, 3, 2, 1)
- count backwards from a number such as 30 or 100.
- breathe into a "portable or preliminary breath tester" or PBT.

Although most law enforcement agencies continue to use a variety of these FSTs, increasingly a 3-test battery of standardized field sobriety tests (SFSTs) is being adopted. These tests are recommended by the National Highway Traffic Safety Administration (NHTSA) after studies indicated other FSTs were relatively unreliable. The NHTSA-approved battery of tests consists of the horizontal gaze nystagmus test, the walk-and-turn test, and the one-leg-stand. In some states, such as Ohio, only the standardized tests will be admitted into evidence, provided they were administered and objectively scored "in substantial compliance" with NHTSA standards (ORC 4511.19(D)(4)(b)).

FSTs are more effective at determining the level of impairment than they are at estimating the driver's blood alcohol concentration (BAC). However, studies question whether the tests increase the officer's ability to judge either. In 1991, Dr. Spurgeon Cole of Clemson University conducted a study on the accuracy of FSTs. His staff videotaped individuals performing six common field sobriety tests, then showed the tapes to 14 police officers and asked them to decide whether the suspects had "had too much to drink and drive". The blood-alcohol concentration of each of the 21 DWI subjects was .00, unknown to the officers. The result: the officers gave their opinion that 46% of these innocent people were too drunk to be able drive. This study showed the possible inaccuracy of FSTs.

An increasingly used field sobriety test involves having the suspect breathe into a small, handheld breath testing device. Called variously a PAS ("preliminary alcohol screening") or PBT ("preliminary breath test"), the units are small, inexpensive versions of their larger, more sophisticated instruments at the police stations, the EBTs ("evidentiary breath test"). Whereas the EBTs usually employ infrared spectroscopy, the PAS units use a relatively simple electrochemical (fuel cell) technology. Their purpose, along with other FSTs, is to assist the officer in determining probable cause for arrest. Although because of their relative inaccuracy they were never intended to be used in court for proving actual blood-alcohol concentration, some courts have begun to admit them as evidence of BAC.

Probable cause to arrest

If the officer has sufficient probable cause that the suspect has been driving under the influence of alcohol, he will make the arrest, handcuff the suspect and transport him to the police station. En route, the officer may advise him of his Miranda rights and his legal implied consent obligation to submit to an evidentiary chemical test of blood, breath or possibly urine.

Laws relating to what exactly constitutes probable cause vary from state to state. In California it is a refutable presumption that a person with a BAC of .08 or higher is driving under the influence. However, section 23610(a)(2) of the California Vehicle Code states that driving with a BAC between .05 and .08 "shall not give rise to any presumption that the person was or was not under the influence of an alcoholic beverage."

Chemical test

At the police station, the arrestee will be offered a chemical test of breath, blood or, much less frequently, urine. Breath test results are usually available immediately; urine and blood samples are sent to a lab for later analysis to determine the BAC or possible presence of drugs.

If the arrestee refuses to submit to chemical testing, he will usually be booked for driving under the influence, there will be no evidence for filing the second charge of driving with .08% blood alcohol content. In some cases the arrestee may be charged with DWI even after passing a breathalyzer test if he or she refuses also to take subsequent urine or blood tests. However, the refusal will carry increased penalties on the driving under the influence charge (typically a longer license suspension and/or an increased jail sentence), and the act of refusing may be admissible in court as evidence of "consciousness of guilt". In some states, refusal to submit to a chemical test can result in an automatic suspension of driving privileges, regardless of whether the suspect is convicted of DWI. In an increasing number of jurisdictions, if the suspect refuses to take a chemical test the police in some states may restrain the individual and forcefully withdraw blood. This is particularly common in situations involving an accident with injury or death. In some jurisdictions this may require obtaining a warrant from a judge. Some commentators, such as Brown University's Jacob Appel, have criticized the role of medical personnel in this process. According to Appel, "If physicians acquiesce today in the removal of a resistant patient's blood, soon they may be called upon to pump the contents of an unwilling patient's stomach or even to perform involuntary surgery to retrieve an evidentiary bullet."

While chemical tests are used to determine the driver's BAC, they do not determine the driver's level of impairment. However, state laws usually provide for a rebuttable legal presumption of intoxication at blood alcohol levels of .08 or higher.

The accuracy of breath, blood and urine testing is a subject of some dispute, with various scientific studies indicating unreliable results (see breathalyzer). In any case, breath and urine tests can only estimate the BAC at the time the test is taken, which can be different than when the vehicle was actually operated.

Booking and charging

If it is determined after arrest that the person's blood alcohol concentration is not at or above the legal limit of .08, they will probably be released without any charges. One may, however, still be charged with driving under the influence of alcohol on the basis of driving symptoms, observed impairment, admissions and/or performance on the field sobriety tests. And if there is suspicion of drug usage, a blood or urine test is likely, or at least the testimony of a specially-trained officer called a Drug Recognition Expert (DRE). Assuming sufficient evidence of impaired driving from drugs, the arrestee may face charges of driving under the influence of drugs or the combined influence of alcohol and drugs.

Most of the time, the driver will either be kept in a holding cell (sometimes referred to as the "drunk tank") until he is deemed sober enough to be released on bail or on his "own recognizance" ("O.R."). A date to appear in court for an arraignment will be given to him. If he cannot make bail or is not granted O.R., he will be kept in jail to wait for the arraignment on remand.

DWI - Law

All states in the U.S. designate a per se blood or breath alcohol level as the threshold point for an independent criminal offense. A second criminal offense of driving "under the influence" or "while impaired" is also usually charged in most states, with a permissive presumption of guilt where the person's blood alcohol concentration (BAC) is .08 percent or greater (units of milligrams per deciliter, representing 8 g of alcohol in 10 liters of blood). Some states (e.g., Colorado) include a lesser charge, sometimes referred to as driving while ability impaired (this may apply to individuals with a .05 percent or above, but less than the .08 per se limit for the more serious charge. The amount of alcohol intake to reach 0.08 percent varies substantially with body composition and health state. Risk of traffic accidents are increased already by far less dosage.

Prior to increased emphasis on drinking and driving in the 1980s, standards of .10-.15 percent were in place. The legal limit for commercial drivers in the U.S. is set at 0.04 percent.All states also observe a much stricter standard for drivers under the age of 21, commonly of .01-.02 these are often referred to as "Zero Tolerance" laws.

Driving under the influence of drugs

Unlike DUI, DWI, or OWUI cases that involve alcohol, there is generally no "per se" or legal limit that is employed for persons accused of driving under the influence of prescription medication or illicit drugs (although this is not the case in Ohio). Instead, the key inquiry focuses on whether the driver's faculties were impaired by the substance that was consumed. The detection and successful prosecution of drivers impaired by prescription medication or illegal drugs can therefore be difficult. Similarly, although urinalysis toxicology screens can detect the presence of such substances in the driver's bloodstream, these analyses are unable to demonstrate that the substance was actually causing impairment at the time of driving. In response to these problems, several jurisdictions are currently considering legislation that would establish "zero tolerance" laws for those drivers arrested for DUI and found to have drugs or medication in their system. Additionally, breathalyzers have been developed for the purpose of administering roadside or laboratory tests that can detect the actual level of a controlled substance in an individual's body.

Penalties

Compared to many other countries penalities for drunk driving, unless involved in an incident involving injury or death of others, are light. Many states do not revoke driving permits even if the offender is convicted multiple times. In most U.S. states drink driving is socialy acceptable in a way that it is not in much of Europe. Many jurisdictions require more serious penalties (such as jail time, larger fines, longer DUI program, the installation of ignition interlock devices) in cases where the driver's BAC is over 0.20, or 0.15 in some places. These additional sanctions are an attempt to deter and punish the operation of a vehicle at extremely high BAC levels and the concomitant danger posed to the safety of persons and property by heavily impaired drivers. In many cases, the reason given for these additional sanctions is because an average person would have passed out from that much alcohol. To be able to drive at that level, a person has to have consumed alcohol regularly for months in order to increase his/her alcohol tolerance and therefore is likely to have driven drunk repeatedly. However, since there is currently no standard test to measure alcohol tolerance, proponents of additional penalties for high-BAC offenders point to some studies that indicate that high-BAC offenders are more likely to be involved in a crash and more likely to recidivate. Critics of such laws point out that due to wide variations of alcohol tolerance, people with high tolerances will suffer the additional penalties, despite being less impaired than those with lower tolerances who drive with much lower BACs.

Some U.S. states also increase the penalties for drunk driving (even to the point of making it a felony) if certain other aggravating circumstances besides a high BAC are present, such as if the drunk driver caused an accident requiring the hospitalization of another person lasting greater than a specified period of time (often 72 hours), in cases where an accident resulted in property damage exceeding a certain amount (often $500), or where the driver has prior (and relatively recent) convictions for drunk driving. In addition, most states observe administrative laws that further penalize people convicted of DUI, typically enforced by the department that issues driver's licenses, usually titled Department of Motor Vehicles (DMV), or Department of Licensing. Australia and the UK have higher alcohol consumption rates, lower ages for alcohol consumption, much lower sentencing regimes for DUI Manslaughter, and much lower incidences of DUI.

This privacy policy explains how this blog collects and uses visitor information. By browsing my blog, you agree in full to this privacy policy. If you have any questions, please contact me.

General Policies

I believe that your personal information, such as your name, email, phone number, and address, is private and confidential. Unless you purposefully enter this information anywhere on my blog, I will not ask for it. In the even that I do receive such information, I will not release it to any third-parties unless you specify me to do so.

Computer Tracking and Analytics

As with most other websites, I collect and use the data contained in log files. The information in the log files include your IP (internet protocol) address, your ISP (internet service provider, such as AOL or Shaw Cable), the browser you used to visit our site (such as Internet Explorer or Firefox), the time you visited our site and which pages you visited throughout our site.

I use Google Analytics and SiteMeter to track visitors, impressions, referals on my blog. This data is used for statistical reasons only, and is disclosed to advertisers. There is no personal information in this data, only tracking such as browser type, length of visit, referring URL, file requests, etc.

This tracking does recognize home IP addresses, browser types, operating system types, and monitor types, but it does not collect email addresses, names, or other information that I could use to identify individual users.

Third Party Advertising

I do use cookies to store information, such as your personal preferences when you visit our site. This could include only showing you a popup once in your visit, or the ability to login to some of our features, such as forums.

I also use third party advertisements to support our site. Some of these advertisers may use technology such as cookies and web beacons when they advertise on our site, which will also send these advertisers (such as Google through the Google AdSense program) information including your IP address, your ISP , the browser you used to visit our site, and in some cases, whether you have Flash installed. This is generally used for geotargeting purposes (showing New York real estate ads to someone in New York, for example) or showing certain ads based on specific sites visited (such as showing cooking ads to someone who frequents cooking sites).

DoubleClick DART cookies

We also may use DART cookies for ad serving through Google’s DoubleClick, which places a cookie on your computer when you are browsing the web and visit a site using DoubleClick advertising (including some Google AdSense advertisements). This cookie is used to serve ads specific to you and your interests (”interest based targeting”). The ads served will be targeted based on your previous browsing history (For example, if you have been viewing sites about visiting Las Vegas, you may see Las Vegas hotel advertisements when viewing a non-related site, such as on a site about hockey). DART uses “non personally identifiable information”. It does NOT track personal information about you, such as your name, email address, physical address, telephone number, social security numbers, bank account numbers or credit card numbers. You can opt-out of this ad serving on all sites using this advertising by visiting DoubleClick DART cookies.

You can choose to disable or selectively turn off our cookies or third-party cookies in your browser settings, or by managing preferences in programs such as Norton Internet Security. However, this can affect how you are able to interact with our site as well as other websites. This could include the inability to login to services or programs, such as logging into forums or accounts.

Deleting cookies does not mean you are permanently opted out of any advertising program. Unless you have settings that disallow cookies, the next time you visit a site running the advertisements, a new cookie will be added.

Release of Information to Government Officials

In the event that systems notice that you may be doing something illegal, I reserve the right to submit your details to proper authorities and government officials. In the event that I'm asked to release information by proper authorities, I will do so.

Driving While Intoxicated

Driving while intoxicated is the act of operating and/or driving a motor vehicle while under the influence of alcohol and/or drugs to the degree that mental and motor skills are impaired. It is illegal in all jurisdictions within the U.S. The specific criminal offense is usually called driving under the influence (of alcohol and/or other drugs, DUI), and in some states driving while intoxicated (DWI), operating while impaired (OWI), or operating a vehicle under the influence (OVI). Such laws may also apply to boating or piloting aircraft.

In the United States the National Highway Traffic Safety Administration (NHTSA) estimates that 17,941 people died in 2006 in "alcohol-related" collisions, representing 40 percent of total traffic deaths in the US. Over 500,000 people were injured in alcohol-related accidents in the US in 2003. NHTSA defines fatal collisions as "alcohol-related" if they believe the driver, a passenger, or an occupant of the vehicle (such as a pedestrian or pedalcyclist) had a blood alcohol content (BAC) of 0.01 or greater. NHTSA defines nonfatal collisions as "alcohol-related" if the accident report indicates evidence of alcohol present. NHTSA specifically notes that "alcohol-related" does not necessarily mean a driver or nonoccupant was tested for alcohol and that the term does not indicate a collision or fatality was caused by the presence of alcohol. On average, about 60 percent of the BAC values are missing or unknown. To analyze what they believe is the complete data, statisticians simulate BAC information. Drivers with a BAC of 0.10 are 6 to 12 times more likely to get into a fatal crash or injury then drivers with no alcohol.
