08% blood-alcohol concentration is the legal measure of drunk driving 0.08% blood-alcohol concentration is the legal measure of drunk driving. A regular 12-ounce beer is 5% alcohol by volume. The normal bloodstream contains 5 liters (169 ounces) of fluid. The maximum blood-alcohol concentration, B, can be approximated by: where n is the number of beers consumed in one hour and w is your body weight in pounds.
