Colorado DUI law & commercial drivers licenses
Drivers of commercial vehicles are subject to Colorado's regular rules pertaining to DUI, DUI per se, and DWAI. But they are also subject to a “legal limit” of .04% blood alcohol concentration (“BAC”).
Driving a commercial vehicle with a BAC of .04% or higher is known as “Excess BAC CDL.” It is prohibited by both federal and Colorado law -- 49 CFR 383.51 and 42-2-126(2)(c) C.R.S., respectively.

Offenses leading to the revocation of your Colorado CDL include (but are not limited to):
- DUI per se
- DUI of drugs
- Excess BAC CDL (.04% or higher)
- Refusing a DUI chemical test
- Leaving the scene of an accident
- Driving without a current valid CDL.1
A first offense carries a minimum revocation of your Colorado CDL for one year.
This increases to 3 years, however, if you were transporting hazardous materials at the time of the violation.2
You have just seven days from being cited for a drunk or drugged driving offense to request a CDL revocation hearing from the Colorado DMV. In addition, you may be charged with applicable criminal penalties for an underlying DUI, chemical test refusal, or other violation.
A second or subsequent DUI and/or chemical test refusal will result in the lifetime loss of your Colorado CDL. You can, however, apply for reinstatement after 10 years (see below).
If you are over 21, you may apply for a driver's license of another class or type if you are otherwise eligible. Such license may be probationary or subject to restrictions (such as completion of an alcohol or drug treatment program or installation of an ignition interlock device).
However, you cannot be granted a probationary or restricted commercial license while your Colorado CDL is revoked or suspended.
If your Colorado CDL is revoked for life, it may nevertheless be reinstated after 10 years if you have voluntarily entered and successfully completed a state-approved alcohol or drug rehabilitation program.
However, if you subsequently commit another disqualifying offense, your CDL may not be reinstated a second time.
Colorado allows drivers under the age of 21 to hold a commercial driver's license. Federal law does not. This means that underage Colorado drivers may drive commercially solely within the state.
Underage commercial drivers are subject to the same laws regarding commercial driver's licenses as adult drivers. In addition, however, they are subject to Colorado's Excess BAC underage CDL law, 42-2-126(2)(e), C.R.S.
Colorado's Excess BAC underage CDL law is the commercial counterpart to Colorado UDD (underage drinking and driving). It is Colorado's “zero tolerance” law for underage commercial drivers.
You violate Colorado's Excess BAC underage CDL law when:
- you are under 21, and
- you drive a commercial motor vehicle with a BAC in excess of .02% (but less than .04%).
Consequences of Colorado Excess BAC underage CDL include revocation of your commercial driving privilege for:
- 3 months for a first violation,
- 6 months for a second violation, and
- 1 year for a third or subsequent violation.
