The legal limit for Blood Alcohol Content in Virginia is 0.08 BAC. If your blood alcohol is 0.08 or higher, operating a vehicle can be a serious criminal offense.
Your BAC (Blood Alcohol Concentration or Blood Alcohol Content) is the amount of alcohol present in your bloodstream. The more you consume, the higher your BAC gets. However, no two people are alike. One person may drink the same amount, over the same period time, and have dramatically different results when his BAC is tested. Your body size, how much you've had to eat, percentage of body fat, and sex are all factors that affect your BAC. A woman’s BAC will almost always be higher than a man’s when consuming the same amount of alcohol.
