Renewing Your CDL in Missouri

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 License Bureau. 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 plus a $2.50 processing fee for a license valid for 3 years
  • $45 plus $5 processing fee or a license valid for up to 6 years

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.

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 newMedical Examination Report (Form 649-F)

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
