What does BAC represent?

BAC stands for Blood Alcohol Concentration, which is a measure of the amount of alcohol present in a person's bloodstream. It is typically expressed as a percentage, indicating the grams of alcohol per deciliter of blood. BAC is commonly used to assess an individual's level of intoxication and is a key factor in legal regulations regarding drinking and driving. Higher BAC levels correlate with increased impairment and greater risks of accidents.
