Driving under the influence (DUI) is the offense of driving, operating, or being in control of a vehicle while impaired by alcohol or drugs (including recreational drugs and those prescribed by physicians), to a level that renders the driver incapable of operating a motor vehicle safely.[1] Multiple other terms are used for the offense in various jurisdictions.
