What you need to do to renew a CDL
Renewing a Commercial Driver's License (CDL) means passing a medical examination, submitting paperwork to your state's DMV, and paying a renewal fee. The process differs from renewing a regular driver's license because the federal government sets minimum standards for CDL holders, even though each state runs its own program. You cannot renew by mail or online in most states — you must appear in person at a DMV office.
The timeline matters: your CDL renewal window typically opens 120 days before expiration and closes on your expiration date. If you let it lapse, you may have to retake the written and skills tests instead of straightforward renewing. Some states allow a grace period of a few days, but do not count on it.
Key Takeaways
- You must pass a Department of Transportation (DOT) medical examination from a certified medical examiner before you can renew, and this exam is separate from the DMV renewal itself.
- Your state's DMV will require proof of citizenship or legal residency, your current CDL, and the completed renewal process form specific to your state.
- Most states charge between $50 and $150 for a CDL renewal, though the fee varies by state and whether you are renewing a single or double endorsement.
- You must renew in person at a DMV office in the state that issued your CDL; you cannot renew in another state even if you live there now.
- If your CDL has expired, you will likely need to retake the written test and pass a skills test with an examiner, not just renew it.
Getting the DOT medical examination
Before you walk into the DMV, you need a DOT medical certificate from a certified medical examiner. This is not your regular doctor — it must be someone on the National Registry of Certified Medical Examiners, which you can search on the Federal Motor Carrier Safety Administration (FMCSA) website. The examiner checks your vision, hearing, blood pressure, and medical history to confirm you can safely operate a commercial vehicle.
The exam costs between $100 and $200 depending on your location and the examiner. You will receive a paper certificate valid for 24 months (or 12 months if you have certain medical conditions). Bring this certificate to the DMV when you renew. If you do not have a valid medical certificate, the DMV will not process your renewal, even if everything else is in order.
Schedule the medical exam at least two weeks before your planned DMV visit. Some examiners book up quickly, especially near the end of renewal windows. If your medical certificate expires before your CDL does, you can renew the certificate without renewing the CDL itself — they operate on separate timelines.
Documents to bring to the DMV
Each state's DMV has a slightly different checklist, but the core documents are the same. Bring your current CDL, your valid DOT medical certificate, proof of citizenship or legal residency (passport, birth certificate, or naturalization papers), and proof of your current address (utility bill or lease dated within the last 60 days). Some states also require your Social Security number or an Individual Taxpayer Identification Number (ITIN).
Fill out your state's CDL renewal process before you go — most states post the form on their DMV website. Arriving with a completed form speeds up the process. If you are renewing a CDL with hazmat endorsement, you will need to pass a background check through the Transportation Security Administration (TSA), which adds time and may require additional documents like fingerprints.
Bring payment in the form your state accepts. Most DMV offices take cash, check, debit card, and credit card, but some accept only certain methods. Check your state's DMV website for the exact renewal fee and accepted payment types.
What happens at the DMV office
When you arrive, you will check in and wait for a clerk to call you. The clerk will review your documents, verify your medical certificate is valid, and process your process. This part usually takes 15 to 30 minutes if your paperwork is complete and correct. The clerk will take a new photo for your license and confirm your address and endorsements.
In most states, you will not retake the written or skills test during a standard renewal — the DMV assumes you remain may have access to if your CDL has not expired. However, if you have certain violations on your record (like a major traffic offense), your state may require you to retake the written test. Ask the clerk before you leave whether any retesting is needed.
You will receive your new CDL on the spot in some states, or by mail within 7 to 14 days in others. Ask which applies to you. If you need to drive commercially before the new card arrives, ask whether you can get a temporary paper permit.
Renewing with a hazmat endorsement
If your CDL includes a hazmat endorsement, the renewal process has an extra step. You must pass a TSA background check, which involves fingerprinting and a records review. This check takes 4 to 6 weeks in most cases, so start the renewal process earlier if you have hazmat.
You will need to visit a fingerprinting location approved by your state — often a local police department or a private fingerprinting service — and submit the results to the TSA. Some DMV offices can fingerprint you on site, but not all. Ask your DMV which route to take. The TSA will notify you and the DMV when the background check is complete, and only then can the DMV issue your renewed CDL with hazmat.
The hazmat endorsement itself does not expire on the same schedule as your CDL. If your hazmat approval expires before your CDL does, you can renew just the hazmat endorsement without renewing the entire license. The TSA charges a fee for hazmat renewal separate from the state CDL renewal fee.
If your CDL has already expired
Once your CDL expires, you cannot legally drive a commercial vehicle, and the renewal process becomes more complicated. You will have to retake the written test covering your state's CDL manual and federal regulations. You will also need to pass a skills test with a state-certified examiner, who will watch you perform a pre-trip inspection, basic vehicle control, and an on-road driving test.
The skills test typically takes 45 minutes to an hour and costs between $100 and $300 depending on your state. You must bring a commercial vehicle that matches your endorsement class (Class A, B, or C) and meets inspection standards. Some testing facilities provide vehicles for a fee, but most require you to bring your own.
If your CDL has been expired for more than a year, some states treat it as a new process rather than a renewal, which may require additional steps like a vision and hearing test at the DMV. Check with your state's DMV about how long you have before the license is considered permanently expired.
State-by-state renewal fees and timelines
| State | Renewal Fee | Validity Period | In-Person Required |
|---|---|---|---|
| California | $100 | 5 years | Yes |
| Texas | $97 | 5 years | Yes |
| Florida | $75 | 8 years | Yes |
| New York | $120 | 5 years | Yes |
| Illinois | $95 | 4 years | Yes |
Renewal fees and validity periods vary by state. The table above shows examples from five large states, but your state may differ. Check your state's DMV website for the exact fee and how long your renewed CDL will be valid. Some states charge extra if you are renewing multiple endorsements or if you need to add a new endorsement during renewal.
The renewal window and grace periods also differ. Most states open the renewal window 120 days before expiration, but some open it earlier or later. A few states offer a short grace period after expiration — typically 30 days — during which you can still renew without retesting, but this is not may provide in your state.
Frequently Asked Questions
Can I renew my CDL in a different state than the one that issued it?
No. You must renew your CDL in the state that issued it, even if you have moved. If you have relocated permanently, you will need to transfer your CDL to your new state, which involves surrendering your old license and taking the written and skills tests in the new state. Contact your new state's DMV for transfer procedures.
What if my medical certificate expires before my CDL does?
You can renew your medical certificate without renewing your CDL. Visit a certified medical examiner, pay the exam fee, and receive a new certificate. Your CDL remains valid as long as you have a current medical certificate on file with your state's DMV. Some states require you to notify the DMV when you renew your medical certificate separately.
Do I have to retake the written test when I renew?
Not during a standard renewal if your CDL has not expired. However, if you have certain violations or your state has updated its CDL manual, the DMV may require a written test. Ask the clerk when you arrive whether retesting applies to you.
How long does the entire renewal process take?
If you have all documents ready and no hazmat endorsement, the DMV visit takes 30 minutes to an hour. You will receive your new CDL when ready or by mail within two weeks. With hazmat, add 4 to 6 weeks for the TSA background check. If your CDL has expired, add time for scheduling and taking the written and skills tests.
What happens if I drive with an expired CDL?
Driving commercially with an expired CDL is illegal and can result in fines, points on your record, and potential suspension of your driving privileges. If you are stopped, you may be cited for operating without a valid license. Renew before your expiration date to avoid these penalties.
