Many traffic accidents are caused by drunk drivers. To prevent traffic fatalities caused by intoxicated individuals, most jurisdictions around the world have laws that forbid individuals to drive a vehicle after consuming alcohol. Some states also put minor charges on drivers whose BAC by volume is 0.05% or higher. For commercial drivers in the United States, the legal BAC by volume limit is 0.04%.
