Explanation
Blood Alcohol Content (BAC) refers to the percentage of alcohol in a person’s bloodstream. Even a BAC as low as 0.02% can impair your judgment, coordination, reaction time, and vision-factors that are essential for safe driving. These impairments greatly increase the risk of a crash. For this reason, most states enforce “zero-tolerance” laws for drivers under 21, making it illegal for them to operate a vehicle with a BAC of 0.02% or higher.
