What does BAC stand for?

Blood Alcohol Concentration is the correct term that describes the percentage of alcohol present in a person's bloodstream. It is a crucial measurement used in various legal contexts, especially related to driving under the influence. BAC is assessed to determine if an individual is above the legal limit for alcohol consumption while operating a vehicle, which in many places, including New York, is typically set at 0.08% for adults.

Understanding BAC is vital for law enforcement and the legal system, as it provides a quantifiable metric to evaluate impairment due to alcohol consumption. This measurement is typically obtained through various methods, including breathalyzers, blood tests, or urine tests, to assess someone's state at the time of driving. While the other options may sound similar, they do not accurately represent the standard terminology used in the context of alcohol measurement.
