All states have laws prohibiting driving under the influence (DUI) of drugs or alcohol. However, some states call the offense by different names, such as “driving while intoxicated” (DWI) and “operating under the influence” (OUI). State laws also differ on how DUI is defined and the consequences of a conviction.
