What does BAC stand for?


BAC stands for Blood Alcohol Concentration (legally known as Blood Alcohol Content). This is the standard measurement for determining alcohol intoxication in Louisiana and the rest of the US. In North America, BAC is defined as the ratio of the mass of alcohol to the volume of blood, expressed as a percentage.
