  • Renewing Your CDL in Colorado

    Compare Commercial Vehicle Insurance Rates in 3 Steps

    1. Enter Your Zip:

    In the state of Colorado, a commercial driver license (CDL) must be renewed every four years. The process is not available online, via mail or over the phone, so you must make a trip to a driver license office to renew in person.

    The requirements are a breath of fresh air when compared to the actual acquiring of a CDL, but there is still plenty to bring along to ensure everything goes smoothly. Of course, if you are a CDL veteran this just might be old hat for you.

    Make sure to bring your expiring CDL license and a current DOT medical certificate. You will also need to bring a check or money order to cover the renewal fee of $35.

    Hazardous Material Endorsement Renewal

    Renewing a new hazmat endorsement, which according to the Federal Motor Carrier Safety Administration (FMCSA) must be renewed, is a bit more complicated. It's the same procedure as getting your first background check.

    Requirements

    • Passing of a Transportation Security Administration background check. E-mail them at patriotact@dhs.gov.
    • Retake the written hazmat test. This is done at the licensing office.

    For fingerprinting, you will need to go to a certified hazmat fingerprinting facility.

    New Federal Requirements

    You must self-certify your type of vehicle operation with the Colorado DMV. This means you must self-certify one of the following driving categories:

    • Non-Excepted Interstate
    • Excepted Interstate
    • Non-Excepted Intrastate
    • Excepted Intrastate

    If you choose Non-Excepted Interstate, you must provide the DMV with a federal medical certificate.
