Know Your Limits, Know the Law
Drinking and driving with a blood alcohol concentration (BAC) under .08 percent is considered a legal activity in all 50 states. In fact, it’s considered to be more dangerous to drive while talking on a hands-free cell phone than it is to drive with a BAC of .08 percent.
Blood alcohol concentration, or BAC, describes the amount of alcohol contained in an individual’s blood and is measured as weight per unit of volume. The measurement is usually converted to a percentage such as 0.10 percent, which indicates that one-tenth of one percent of a person’s blood is alcohol. The amount of alcohol it takes to reach a concentration of .08 percent varies on a person’s size, gender, and how empty their stomach is. Responsible drivers know to keep these variables in mind when having a drink.
