When to Renew

Missouri will send you a postcard reminder before your CDL expires. The postcard will be mailed to the address on your driving record, so be sure to keep your address current with the Department of Revenue's Driver Licensing Division. It is still your responsibility to renew your license on time, even if you don't receive the postcard.

The front of the postcard will explain your renewal fees, which are the same as getting a new license:

• $22.50 for a 3-year license

• $45 for a 6-year license

You can renew your license no earlier than six months before your license expires. You'll be required to take a vision test and a highway sign recognition test when you renew.

If you fail to renew your license before it expires, you must not drive. If you do not renew your license within six months (or 184 days) after its expiration date, you will have to re-take the written and road tests.

How to Renew

If you're ready to renew your CDL, the state of Missouri requires a background check into your driving status. Before issuing a renewal the state will request information from the National Driver Register and the Commercial Driver License Information System (CDLIS). You may also be asked to have a new physical exam.

When you renew your Missouri CDL, you'll be required to provide proof of your identity, residency, and legal presence in the United States. This is necessary to comply with Missouri's "Show Me Proof" legislation.

Adding a Hazardous Materials Endorsement

If you're wanting to add or renew a hazardous materials (hazmat) endorsement you must submit an application and fingerprints to the Transportation Security Administration (TSA). This costs $89.25.
