Explanation
It is illegal for any person 21 years of age or older to operate a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher. Alcohol impairs a person's ability to safely operate a vehicle, so the legal limit of 0.08% or higher is set to ensure that all drivers are not impaired while operating a vehicle.
