Understanding Blood Alcohol Concentration: Legal Insights and Definitions
Definition & meaning
Blood alcohol concentration (BAC) refers to the amount of alcohol present in a person's bloodstream. It is typically expressed as a percentage, indicating the mass of alcohol per volume of blood. For example, a BAC of 0.08 percent means that there are 0.08 grams of alcohol for every 100 milliliters of blood. This measurement is crucial in various contexts, particularly in assessing impairment related to driving and legal standards for alcohol consumption.
