How is the amount of alcohol in your body typically measured?

The measurement of the amount of alcohol in a person's body is most commonly quantified as Blood Alcohol Concentration, or BAC. BAC is expressed as a percentage and indicates the grams of alcohol present in a deciliter of blood. This measurement provides law enforcement and medical professionals with a clear and standardized way to evaluate a person's level of intoxication, which is crucial for determining eligibility to operate a vehicle or for understanding potential impairments.

This method of measurement is widely recognized and utilized in legal settings and clinical assessments, making it an essential component of safe driving regulations and public health initiatives. It is vital for school bus drivers and others responsible for transporting passengers to understand these measurements to maintain safety standards.
