Ignition Interlock Laws in Colorado

Colorado State SealThere are two types of suspensions that can result from a DUI or DWAI in Colorado:

  1. Administrative – This is an automatic suspension, imposed by the Colorado Department of Revenue upon arrest if your blood alcohol concentration (BAC) is .08 or higher
  2. From the criminal court. This occurs when you are sentenced by a court after a trial or plea agreement

Colorado has two designations for impaired driving: DUI (Driving Under the Influence) and DWAI (Driving While Ability is Impaired). DWAI is the designation for drivers whose BAC is between .05 and .08.
