Some states refers to it as Driving Under the Influence (DUI), others refer to it as Driving While Intoxicated (DWI) and a small group of states called it Operating Under the Influence (OUI). (We generally refer to it as "DUI" at this site.) This criminal offense generally includes either driving under the influence of alcohol to the extent it impairs your physical and mental faculties, or driving while you have a blood alcohol content of .08 or greater regardless of whether the alcohol has had any effect on you. The offense is also mistakenly known as “drunk driving” although that term has no official meaning and is a misnomer because you don’t have to be drunk (or driving) in order to be arrested and convicted of a DUI. We've provided state specific information as well as some general information to help you, your friends, or your family, plot a course for the individual arrested for a DUI.
