D.U.I. is an American reality television series series featuring police officers. The show premiered on on December 1, 2011 on TLC, and is a similar format to COPS, but focuses exclusively on suspects arrested for driving under the influence of alcohol or drugs. However, unlike COPS, the show will also follow the suspects through the legal system, and will show the personal consequences of their decision to drink and drive for each individual. The first six episodes of the series aired in 2011, with the next six following in 2012.

The series was shot in Oklahoma in Pontotoc, Cleveland, Sequoyah, Tulsa and Oklahoma counties, and features local sheriff's deputies from those counties, as well as Oklahoma Highway Patrol troopers. The show's producers said that Oklahoma was chosen for a shooting location because the state has one of the fastest DUI turnarounds in court, as well as some of the strictest DUI laws in the United States.
