What is the legal BAC limit that indicates a person is intoxicated?

The legal Blood Alcohol Concentration (BAC) limit that indicates a person is considered intoxicated is 0.08. This is the standard threshold used in many states, including Indiana, for determining legal impairment while operating a vehicle, including motorcycles. At or above this level, an individual's ability to operate a vehicle safely is significantly compromised due to the effects of alcohol on judgment, coordination, and reaction times. This standard helps law enforcement and the legal system assess impairment and promote road safety by discouraging drunk driving. Lower BAC levels, while still potentially impairing an individual’s driving ability, have not been established as the legal limit for intoxication in the context of operating a vehicle.
