What does BAC stand for?

BAC stands for Blood Alcohol Content, which is a measurement used to determine the amount of alcohol present in a person's bloodstream. It is expressed as a percentage indicating the mass of alcohol per deciliter of blood. Understanding BAC is crucial in law enforcement and legal contexts, particularly regarding DWI (Driving While Intoxicated) laws, where specific BAC levels can determine legal impairment thresholds.

In New York, for example, a BAC of 0.08% or higher is the legal limit for operating a vehicle. This measurement plays a critical role in evaluating a driver's impairment and enforcing sobriety laws. The other options, while related to alcohol measurement or topics, do not accurately reflect what BAC stands for or represent.
