Colorado DUI and CDL information
Colorado DUI and Commercial Driver's Licenses
A Colorado DUI or DWAI matter involving a commercial driver can extend beyond the criminal court. The same event may create a court case, a separate DMV record, and questions under state and federal commercial-driver rules.
A charge, arrest, test result, refusal allegation, administrative finding, conviction, and commercial disqualification are not interchangeable records or events.
Consultations and office visits are by appointment only.
General public information

One event can involve separate legal systems
The court addresses the filed Colorado DUI or DWAI charge. Colorado DMV separately administers driving records and administrative licensing action. Commercial driving privileges are also governed by Colorado's commercial-driver statutes and federal CDL regulations.
Those systems use different records and legal standards. A court disposition does not by itself describe every DMV or commercial-license consequence, and an administrative action does not decide the criminal case.
The federal major-offense framework
Federal regulation 49 C.F.R. section 383.51 contains separate tables for major offenses, serious traffic violations, railroad-highway grade-crossing offenses, and out-of-service-order violations. The major-offense table includes specified alcohol-related, controlled-substance, testing-refusal, accident-scene, felony, disqualified-driving, and fatality-related convictions.
The regulation uses different columns according to the offense and whether the driver was operating a commercial or noncommercial vehicle. The precise conviction, vehicle classification, administrative record, and prior qualifying incidents matter more than a generic label such as DUI case.
Personal and commercial vehicles are not the same analysis
Some federal major-offense categories can apply to a CDL holder after a qualifying conviction involving a noncommercial vehicle. Other provisions are tied specifically to operation of a commercial motor vehicle. FMCSA separately identifies an alcohol standard for commercial-motor-vehicle operation.
A personal-vehicle incident is therefore not automatically outside the commercial-license system, but it also does not follow every commercial-vehicle-specific rule. The governing federal table and final record control the classification.
Colorado adds a commercial-driver layer
Colorado's commercial-driver statutes operate alongside other state driver-license laws. For commercial-license purposes, state law addresses identified DUI, DUI per se, and DWAI convictions, substantially similar out-of-state convictions, and specified administrative determinations.
Colorado DMV also describes the criminal court case and the DMV administrative process as separate matters. A commercial-driver question can therefore involve the filed charge, the DMV record, and the federal disqualification framework at the same time.
Interstate records and employment are separate subjects
FMCSA explains that states use the Commercial Driver's License Information System and the National Driver Register to exchange information about CDL holders, traffic convictions, and disqualifications. The home licensing state maintains the commercial credential, while the state where a conviction occurs has federal reporting responsibilities.
A 2026 federal final rule removed a separate federal self-reporting requirement for certain out-of-state convictions because state agencies use electronic exchange. Separate employer-notification provisions and employment policies can remain relevant. This page does not determine a duty under federal law, state law, an employer policy, or a collective-bargaining agreement.
