DUI is a common term used for driving under the influence of alcohol or drugs, although there are a variety of other terms used throughout the United States including OWI, OUI, OVI, DMAW, OMVI and DUII.

Driving under the influence means that "your mental and/or physical faculties are impaired to such a degree that you no longer have the ability to drive with the caution characteristic of a sober person." Under DUI laws, drivers may be arrested if they are under the influence of any intoxicating substances (illegal, prescription, or even over-the-counter) and they are not able to safely operate their motorized vehicle. Their blood alcohol concentration (BAC), if they have consumed alcohol, does not have to be above the illegal limit to be convicted of DUI.
