The Basics

A Connecticut commercial driver's license (CDL) is good for four years. Within 60 days of your renewal date you should receive a renewal application from the Department of Motor Vehicles through the U.S. Mail. You need to renew your CDL in person at any Connecticut DMV full-service office. Bring the following items with you in order to complete the renewal process:

• Your current CDL (If you do not have your current CDL, you must present two acceptable forms of identification.

• Original U.S. Department of Transportation Medical Certificate (completed and dated within two years of renewal).

• The renewal application form that you received in the mail.

• $60 ($108 if you have a public passenger endorsement or restriction).

Hazmat Endorsement

If you have a hazmat endorsement, it's time to get a new background check. Allow at least 30 days to complete this. The procedure is not so much as a renewal as it is a whole new check; see Applying for a New CDL for full details. The cost is $89.25.
