Drunk Driving Driving Laws by State

DWI Blood Alcohol Limits across the country
Lower BAC
Higher BAC

Updated: July, 2017

Drunk Driving laws exist in every state and are mandated by the federal government. States without laws against drunk driving receive less federal funding for roads.

In all states the legal limit for driving is below 0.08% Blood Alcohol Content (BAC). Driving above this limit is known as Driving under the Influence (DUI) in most states. In all but 2 states (Vermont and Mississippi) there is a second higher BAC limit above which you are considered Driving While Intoxicated (DWI). Driving While Intoxicated carries stricter mandatory sentences including increased fines, loss of license, forfeiture of car, and even jail time for a first offence in some states.

The map above shows the BAC limit for Driving While Intoxicated in each state.
