Understanding BAC
Blood Alcohol Concentration (BAC) is the amount of alcohol present in the bloodstream, expressed as a percentage. As BAC increases, alcohol can impair judgment, coordination, reaction time, and decision-making.
Even relatively low BAC levels may affect driving ability, concentration, and balance. The effects vary significantly from person to person.
