Ignition Interlock Laws

In Colorado, there are two different classifications of impaired driving under the DUI laws, which are determined by the BAC of the driver.

  • A driver with a BAC between .05% and .08% is considered to be Driving While Ability is Impaired (DWAI).
  • A driver with a BAC greater than .08% is considered to be Driving Under the Influence (DUI).
    Colorado drivers with licenses suspended because of DUI or DWAI may apply to have their licenses reinstated after 1-2 months of suspension. The reinstatement is contingent upon the driver’s agreement to install ignition interlock devices in all vehicles that he or she owns, co-owns, or operates.

License Suspension

Administrative Suspension

Drivers charged with DUI face an automatic and immediate suspension of their license. The automatic suspension is administered by the Colorado Department of Revenue. Repeat DWAI offenders also face automatic suspension.

Judicial Suspension

In most cases, Colorado ignition interlock laws state that convicted drivers will be subject to a period of license suspension after which they may apply for a restricted license which allows them to drive under the control of an ignition interlock device. The length of both the suspension and restriction periods depends on the conviction history of the driver.

First-time offenders face a six-month suspension and a five-month restriction period.

Four-time offenders are subject to a four-year suspension and may apply for a restricted license after 18 months.

Some DUI offenses, especially those involving an accident or injury to another person, may be charged as a felony rather than a misdemeanor. In these cases, suspension and restriction penalties are more severe.
