To renew a CDL-A, you go through your state licensing agency (DMV, DPS or similar) before the expiration date on your license, re-certify the type of driving you do, show proof of citizenship or lawful status and state of domicile if the state asks, and keep your DOT medical certification current on your record. Federal rules cap a CDL at 8 years per renewal, the state must check the Drug and Alcohol Clearinghouse first, and if you want to keep a hazmat endorsement you must retake the hazmat knowledge test and pass a TSA security threat assessment (as of November 2026). The exact renewal cycle, fee and whether you can renew online are set by your state.
This guide is for working CDL-A drivers who already hold the license and want the CDL renewal to go through without a gap in driving time, a lost endorsement or a surprise at the counter.
How often do you have to renew a CDL-A?
It depends on your state, but there is a federal ceiling. Under 49 CFR 383.73(d), a state must make a renewed CDL valid for no more than 8 years from the date of issuance. Many states use shorter cycles, and some tie the expiration to your birthday. Check the date printed on your license and your state agency's CDL page rather than assuming your cycle matches a friend's in another state.
Your DOT medical card runs on its own clock (up to 24 months, often less), so most drivers re-certify medically several times between license renewals. We cover that side in our DOT medical card renewal guide.
What do you need to renew a CDL-A?
Federal rule 49 CFR 383.71(d) lists what every renewal applicant must give the state. As of November 2026, you must:
- Make the self-certifications again: the type of operation you drive (non-excepted interstate, excepted interstate, non-excepted intrastate or excepted intrastate) and that you are not disqualified and hold only one license.
- Update your license information (name, address and other details required on the CDL).
- List every state where you held any driver's license in the past 10 years.
- Provide proof of citizenship or lawful permanent residency (or non-domiciled registration) and proof of state of domicile, such as a government-issued tax form with your name and home address.
- Keep your hazmat endorsement qualified if you want to keep it (see below).
Most OTR and regional CDL-A drivers certify as non-excepted interstate, which means the state must see a "certified" medical status on your driver record. If your medical certificate has lapsed on file, fix that first.
States also commonly ask for a vision screening, a renewal fee and a new photo. Those details vary, so pull your state's checklist before you go.
What does the state check before it renews your CDL?
Before renewing, 49 CFR 383.73(d) requires the state to:
- Run a check of your driving record through the national systems (CDLIS and the National Driver Register).
- Verify your Social Security Number if that hasn't been done before.
- Verify proof of citizenship or lawful status and domicile, where required.
- Query the Drug and Alcohol Clearinghouse. Since November 18, 2024, the state must request your Clearinghouse record (49 CFR 382.725). If it shows you are prohibited from operating a CMV, the state must not issue, renew or upgrade your CDL.
If you have an unresolved violation from years back, the renewal is where it surfaces. Log in to the FMCSA Clearinghouse before your renewal window and check your status. Our Clearinghouse guide for CDL-A drivers walks through how.
Do you have to retest to renew a CDL-A?
For a standard on-time renewal of a Class A CDL, federal rules do not require you to retake the general knowledge or skills test. The big exception is hazmat: under 383.71(d)(3), to keep the H endorsement you must pass the hazmat knowledge test again (49 CFR 383.121) and meet the TSA threat assessment standard.
Some states add their own retest rules, especially if your license has been expired for a long time. If you let a CDL lapse past your state's limit, you may be treated like a new applicant, so don't let it get that far.
How do you renew a hazmat endorsement?
The TSA's HME page says you generally must renew the security threat assessment every five years, and some states require it more often to match shorter license cycles. As of November 2026:
- The fee for new and renewing applicants is $88.25 (after an FBI fee increase effective October 1, 2026), or $41 if you already hold a valid TWIC.
- You submit new fingerprints at renewal.
- TSA recommends enrolling at least 60 days before you need the determination, and notes some processing times may exceed 45 days.
If hazmat freight is part of your pay, start the TSA process first, then the state renewal. For more on the endorsement itself, see our guide to adding hazmat, tanker and doubles endorsements.
Worked example: planning a CDL-A renewal (hypothetical)
This is a hypothetical example to show the timing, not a real driver.
A CDL-A driver's license expires on March 31. They haul tanker and hazmat loads, and their medical card expires June 15 of the same year.
- Mid-December (about 105 days out): enroll for the TSA HME renewal. Adding TSA's recommended 60-day minimum plus a 45-day cushion for slow processing gives 105 days.
- January: log in to the Clearinghouse and confirm there are no open violations; request a copy of the state driving record to spot errors.
- Early March: book the state renewal visit with documents ready, retake the hazmat knowledge test, and pay the state fee.
- May: schedule the DOT physical so the new medical certificate is on file before June 15.
Planned this way, the license, endorsement and medical status never lapse at the same time, and no loads are lost waiting on paperwork.
What happens if your CDL expires?
An expired CDL means you can't legally drive a CMV until it is renewed, and your carrier has to pull you off the board. States set their own grace periods (if any) and late-renewal rules, and a long lapse can mean retesting. Separately, if your medical status lapses on your record, your state can downgrade your CDL even if the license itself hasn't expired. A clean, current license also matters when you look at new CDL-A jobs, because carriers check your MVR and license status during hiring.
Common mistakes
- Waiting until the last week. Appointment backlogs and document problems can push you past expiration.
- Forgetting the TSA step for hazmat. The state can't keep your H endorsement without a current threat assessment.
- Assuming the medical card renews with the license. It doesn't; they are separate deadlines.
- Not updating your address. Renewal notices go to the address on file, and many states treat a move to a new state as a transfer, not a renewal.
- Ignoring old tickets or Clearinghouse issues. The state checks both. See how violations affect your CDL-A.
- Bringing the wrong documents. Use your state's checklist for proof of citizenship or status and domicile.

Frequently asked questions
Can I renew my CDL-A online?
Some states allow online or mail CDL renewal for certain drivers, while others require an in-person visit, especially for hazmat or when proof of citizenship has not been checked before. Check your state agency's site.
How early can I renew my CDL?
Each state sets its own early renewal window. Federal rules only cap the validity at 8 years.
Do I need a new DOT physical to renew my CDL?
Not automatically, but if you certify as non-excepted interstate the state must see a current "certified" medical status on your record. If your medical card is close to expiring, get the physical done first.
How much does it cost to renew a hazmat endorsement?
As of November 2026, TSA's fee is $88.25 for new and renewing applicants, or $41 with a valid TWIC, plus whatever fee your state charges for the license and endorsement.
Can a Clearinghouse violation stop my CDL renewal?
Yes. If the Clearinghouse shows you are prohibited from operating a CMV, the state must not renew or upgrade your CDL until the return-to-duty process is complete.
