driving under the influence

Driving under the influence (DUI) or Driving while intoxicated (DWI) is the crime of driving a motor vehicle while impaired by alcohol or other drugs (including those prescribed by physicians), to a level that renders the driver incapable of operating a motor vehicle safely. The name of the offense varies from jurisdiction to jurisdiction and from legal to colloquial terminology. Other terms include: drink-driving, drunk driving, drunken driving, impaired driving, operating under the influence, drinking and driving, over the prescribed limit (OPL). People who receive multiple DUIs are often struggling with alcoholism or alcohol dependence.
