What does BAC stand for in the context of driving and alcohol consumption?

The correct answer is "Blood Alcohol Content." BAC is a widely used term that describes the concentration of alcohol in a person's bloodstream. It is expressed as a percentage, which indicates the volume of alcohol present in a specific volume of blood. For instance, a BAC of 0.08% means that there are 0.08 grams of alcohol per 100 milliliters of blood. This measurement is crucial in the context of driving because legal limits for driving under the influence are often set based on BAC levels. Understanding BAC is vital for recognizing how alcohol impairment affects driving ability and the legal implications of exceeding established BAC limits.
