Understanding Blood Alcohol Content (BAC)
Blood Alcohol Content (BAC) is a measure of the amount of alcohol in your bloodstream. It's typically expressed as a percentage. For example, a BAC of 0.08% means that 0.08% of your blood volume is alcohol.
Remember: It's never safe to drink and drive, regardless of your BAC level.
