Renewing Your CDL in Connecticut

The Connecticut Department of Motor Vehicles (DMV) has a specific process in place for renewing a commercial driver’s license (CDL).

If it’s time for you to complete the CDL renewal process, or if you are just trying to prepare in advance, keep reading to see what steps you will need to follow in order to do so.

Renewing a CT Commercial Driver’s License

In Connecticut, your CDL will need to be renewed every 4 years, at least 1 week before your birthday. You should expect to receive a renewal form in the mail to the address* you have on file at the DMV.

You will ALSO need an up-to-date medical certificate done by a certified medical examiner on record with the DMV office BEFORE you renew. See our section about the medical certificate below for details.

When you head to your local DMV office to renew your CDL, bring your:

  • Completed renewal application form.
  • Printed receipt of confirmation that you are self-certified with the DMV. You can self certify on the DMV self-certification page.
  • Current commercial driver’s license.
    • If you don’t have your current license, you will need to bring 2 documents proving your ID.

If you would like to get a license that is federally compliant with the REAL ID Act, you should also be prepared to show documents proving your:

  • Identity.
  • Social Security number.
  • Legal U.S. presence.
  • CT residence (2 documents).
  • Name change (if applicable).

The Connecticut DMV website has a REAL ID document checklist with a full list of acceptable documents.

Once you complete the renewal process at the DMV, you will be given a temporary paper card to hold on to, along with your expiring license, while you wait for your new license to come in the mail.

*By law, you have 48 hours to inform the DMV if you are to change addresses. If you don’t receive your notice in the mail, please contact the DMV at (800) 842-8222.
