Drunk Driving and DUI Laws

Drunk driving has increased among college students over the past few years. This is according to a report from the National Institute on Alcohol Abuse and Alcoholism (NIAAA). An estimated 2.8 million drove while under the influence of alcohol in 2001, compared to 2.3 million in 1998.

You should always question whether it is safe to drive after consuming any amount of alcohol. Impairment can begin long before a person reaches the blood alcohol concentration (BAC) level necessary to be guilty of drunk driving. In all 50 states, the legal limit for drunk driving is a BAC level of .08. A 120-pound woman can reach a .08 BAC level after only two drinks and a 180-pound man can be at .08 after only four drinks. A drink is considered one shot of liquor, a five-ounce glass of wine, or one beer. Impairment begins with the first drink. It is important to note that the effects of alcohol intoxication are greatly influenced by individual variations among users. Some users may become intoxicated at a much lower BAC than others. Driving under the higher levels of impairment seems an impossibility, but you commonly see DUI arrests with these extreme BACs.

These changes may be very subtle or barely noticeable at this level.

When driving, a person with a .05 BAC would be operating the vehicle with reduced coordination, a further diminished ability to track moving objects, difficulty in steering, and a reduced response in emergency situations. The person may experience intensified emotions.

  • .08 BAC level

.08 is the level of legal intoxication. Drivers will experience poor muscle coordination, affecting their balance, speech, vision, reaction time and hearing.
