What does the acronym BAC stand for?

The acronym BAC stands for Blood Alcohol Concentration. This term refers to the percentage of alcohol (ethanol) present in a person's bloodstream. It is a critical measurement used to determine an individual's level of intoxication and is a key factor in assessing impairment due to alcohol consumption. In many jurisdictions, specific BAC limits are enforced to define legal impairment while driving, typically 0.08% for adults in many places. Understanding BAC is essential for both law enforcement and individuals as it highlights the effects of alcohol on the body and the corresponding legal implications of exceeding established limits.
