Driving Under the Influence/Driving While Ability Impaired

The two primary alcohol‑ and drug‑related driving offenses in Colorado are driving while under the influence (DUI) or driving while ability impaired (DWAI).  Except in certain circumstances, both of these offenses are misdemeanors.  In 2015, Colorado enacted House Bill 15‑1043 which establishes a felony offense for the fourth and subsequent offense of DUI, DUI per se, DWAI, or other serious vehicular crimes involving drugs and alcohol.  For more information, please reference Legislative Council Staff's Driving Under the Influence of Drugs or Alcohol Issue Brief, the Department of Revenue's website on Alcohol DUI, or the Department of Transportation's website on Alcohol and Impaired Driving.

To report a DUI Driver, dial *277 (*CSP).  For more information on this program, visit the Colorado State Patrol's website.
