driving under the influence (DUI)
n. commonly called "drunk driving," it refers to operating a motor vehicle while one's blood alcohol content is above the legal limit set by statute, which supposedly is the level at which a person cannot drive safely. State statutes vary as to what that level is, but it ranges from .08 to .10. Driving on private property such as a parking lot is no defense, but sitting in a non-moving vehicle without the ignition on probably is (sometimes resulting in a charge of "drunk in and about a vehicle"). This is a misdemeanor and is variously referred to as DUI, driving while intoxicated (DWI), drunk driving, or a "deuce".
n. short for driving under the influence of alcohol. (See: driving under the influence)
