Quick Summary

Drunk driving, also known as driving under the influence (DUI) or driving while intoxicated (DWI), refers to the act of operating a vehicle while impaired by alcohol or drugs. This is a serious offense with significant legal consequences.123

In the United States, laws are in place to penalize drunk driving. These laws often set a legal limit for blood alcohol content (BAC) for drivers. Exceeding this limit or driving while impaired can lead to arrest, convictions, and penalties such as license revocation. Many states have lowered the legal BAC limit and increased penalties due to the high percentage of traffic fatalities involving alcohol.234
