Renewing a Missouri Commercial License

Renewing your Commercial Driver License (CDL) in Missouri involves more steps than a standard driver’s license renewal. Commercial drivers must comply with both state and federal requirements to ensure their CDL remains valid and active.

When to Renew Your Missouri CDL

Missouri CDLs must be renewed every 5 years. It’s important to start the renewal process early to avoid a lapse in driving privileges. You can renew up to 6 months before the license expiration date. If your CDL expires, you may be subject to retesting and penalties.

Required Documents for CDL Renewal

To renew your Missouri CDL, you must visit a local Missouri Department of Revenue (DOR) office in person and provide the following:

• Your current Missouri CDL
• Proof of identity, such as a birth certificate or U.S. passport
• Proof of Missouri residency (e.g., utility bill, lease agreement)
• Proof of Social Security number (e.g., Social Security card, W-2)
• A valid Medical Examiner’s Certificate (if required for your CDL class)
• Any applicable renewal fees

For medical documentation specifics, visit the Missouri CDL Medical Certificate Guide.

Medical Certification Requirements

If you drive a commercial vehicle that requires a medical certification, you must have an up-to-date Medical Examiner’s Certificate (Form MCSA-5876) on file. Drivers must submit this to the Missouri DOR and keep a copy with them while operating a commercial vehicle.

Failure to maintain or update this certificate can result in CDL disqualification. Learn more at the Missouri CDL Medical Certificate Guide.

CDL Renewal Process

1. Schedule an Appointment: While walk-ins are accepted, appointments help reduce wait times. You can book an appointment online.
2. Visit a DMV Office: Go to your local DOR office. For help locating one, use the Missouri DMV Office Locations Guide.
3. Present Required Documents: Submit all necessary documentation and complete any applicable tests.
4. Pay the Renewal Fee: Fees vary based on the class and endorsements on your license. Refer to the Fees for Missouri Driver’s License for exact amounts.
5. Receive Your Temporary License: You’ll get a temporary paper license valid until your new CDL arrives by mail.

Updating Information During Renewal

If you’ve changed your name or moved recently, update your records during the renewal process. Learn how to do this through the Updating Your Name or Address on Missouri License resource.

Additional Endorsements and Hazmat Background Check

Certain endorsements, like HAZMAT (Hazardous Materials), require additional testing and a federal background check. Be sure to begin this process well in advance of your renewal date if applicable.

Lapsed or Expired CDLs

If your CDL has been expired for over 6 months, you may be required to retake the written and/or skills test. It’s critical to renew on time to avoid additional testing or disqualification.
