Driving under the influence of alcohol or other impairing drugs is a crime in all 50 states including the District of Columbia. Whether your state calls it “driving under the influence (DUI),” “driving while intoxicated (DWI),” There is no difference. The laws governing impaired driving are also enforceable when operating boats, bicycles or other types of machinery.
After a person is arrested on suspicion of a DUI, it’s up to the district attorney’s office to file charges against the defendant. The exact nature of criminal charges be they a felony or misdemeanor depends on a number of factors, including the defendant’s prior convictions, the severity of the offense, the level of intoxication, and whether the offense caused injury or death.
