The laws relating to drunk driving differ from one state to another, and even vary in terminology ("drunk driving", "DUI" or "driving under the influence", "DWI" or "driving while intoxicated", "OWI" or "Operating While Intoxicated", "impaired driving", etc.). These differences can involve the legal definitions of the offense ("operating" and "driving", for example, can involve significantly different conduct, as can what constitutes "impaired"), effects on license suspensions and/or restrictions, the nature of court and administrative procedures, nature and severity of penalties, what conduct constitutes a felony, and so on. Although this is changing with the increasing presence of the federal government's "carrot-and-stick" approach to uniformity, primarily through the acitvities of the Department of Transportation's National Highway Traffic Safety Administration ("NHTSA", pronounced "nitsuh"), the differences are still substantial and are likely to remain so for some time.
