What does BAC stand for in driving safety?

BAC stands for Blood Alcohol Concentration. This term is crucial in driving safety as it quantifies the amount of alcohol present in a person's bloodstream, expressed as a percentage. Understanding BAC is essential for assessing impairment while driving, as higher levels of alcohol in the blood correspond to greater impairment of cognitive and motor functions. Therefore, knowing and managing one's BAC is a vital aspect of responsible driving, aimed at reducing the risk of accidents caused by alcohol consumption. This concept underscores the legal limits set for drivers, which often dictate the maximum allowable BAC to ensure public safety on the roads.
