CDL Renewal Checklist — What to Do Before Your CDL Expires
CDL renewal requirements vary by state, but most require a current DOT medical certificate, a vision check, and payment of renewal fees. Some states require knowledge tests for endorsement renewal.
Important Notice
Renewal procedures and fees vary by state. Check with your state CDL agency for their specific requirements.

Plan ahead — don't let your CDL lapse
A lapsed CDL means you cannot legally operate a CMV until it is renewed. Many states allow early renewal starting 6 to 12 months before the expiration date — renewing early does not reset the clock. The new expiration is typically calculated from the original expiration, not from the renewal date. This means renewing six months early doesn't cost you six months of validity on the back end. Check your state DMV for their specific early renewal window and whether there are any restrictions on how far in advance you can renew.
Medical certificate and CDL renewal
Interstate CDL drivers certified as non-excepted interstate (NI) must maintain a valid DOT medical certificate. At renewal, most states require either electronic confirmation or a submitted copy of the current medical certificate on file with their licensing system — not just proof that you had a physical. If the medical certificate on file with the state has expired and a new one hasn't been submitted, the state may downgrade the CDL to a non-commercial license regardless of when the CDL card itself expires. This downgrade can happen without the driver receiving immediate notice, and it becomes visible to employers and enforcement through the MVR and CDLIS.
HazMat endorsement renewal — the timeline that trips up drivers
The HazMat (H) endorsement runs on a 5-year TSA background check cycle independent of the CDL card expiration. A driver whose CDL renewal is due in March and whose H endorsement expires in November needs to start the TSA application in August or September — not wait until CDL renewal time. TSA processing typically takes 5 to 10 weeks. If the endorsement lapses before CDL renewal, the H code is removed from the CDL immediately. Restoring it requires completing a new TSA assessment and knowledge test even if the CDL is current. Track the H endorsement expiration separately.
Knowledge retesting at renewal
Most states do not require full CDL knowledge test retesting at renewal — the standard renewal process is document verification, medical certificate confirmation, and fee payment. However, some states require a vision exam at renewal. A few require endorsement knowledge retesting (particularly hazmat) on a periodic basis or when the endorsement has lapsed. Check your specific state's renewal requirements before the appointment. Some states have moved to online or mail renewal for experienced CDL holders; others still require an in-person visit.
Renewing after moving to a different state
If you moved to a new state since your last renewal, you must transfer your CDL to your new state of domicile before renewing. The new state will pull your CDLIS record and issue a CDL reflecting your existing class, endorsements, and restrictions. If the CDL from the original state expires before the transfer is completed, the situation varies by state — some new states will process the transfer from an expired CDL; others treat it as a new application requiring retesting. Contact the new state's CDL agency before your expiration date to confirm their procedure. Some states require transfer within 30 to 90 days of establishing residency.
Frequently Asked Questions
What happens if my CDL expires?
Operating a CMV with an expired CDL is a federal violation. You cannot legally drive commercially until the CDL is renewed. Some states require retesting if the CDL has been expired for an extended period — typically 12 months or more. Don't let the CDL lapse; renew before the expiration date.
Can I renew my CDL at any state DMV, or only the one that issued it?
CDL renewal must be done with your state of domicile — the state where you currently live and maintain your primary residence. If that's still the same state that issued your CDL, renew there. If you've moved, you first need to transfer the CDL to the new state before renewing.
Does CDL renewal cost money, and how much?
Yes. CDL renewal fees are set by each state and vary from around $20 to over $100 depending on the state and CDL class. Some states charge additional fees for endorsements or vision testing. Check your state DMV's fee schedule before your renewal appointment.
Does my CDL renewal affect my self-certification status with the state?
At renewal, many states review the self-certification on file and may prompt drivers to confirm or update it. If your medical certificate has changed or your operating category has changed since the last certification, renewal is a natural time to update it. Verify with your state DMV whether self-certification is reviewed as part of the renewal process or requires a separate update.
