Endorsements Don't Expire — They Stay Until You Remove Them
An endorsement on your commercial driver's license stays there for the life of that license unless you actively remove it or your license is suspended, revoked, or not renewed. Unlike the license itself, which expires every few years, an endorsement is permanent once you pass the test and pay the fee. If you earned an air brake restriction waiver in 2015, it will still be there in 2025 unless you take a step to get rid of it.
The confusion usually comes from mixing up two different things: the license expiration date and the endorsement status. Your CDL expires (typically every four or eight years, depending on your state), but when you renew it, your endorsements renew with it automatically. You do not have to retake endorsement tests or pay endorsement fees again just because your license came up for renewal.
The only time an endorsement disappears is if you lose your license entirely — through suspension, revocation, or straightforward letting it lapse by not renewing — or if you formally request its removal from your state's Department of Motor Vehicles (DMV).
Key Takeaways
- Endorsements remain on your CDL for as long as you hold that license; they do not expire on a separate schedule.
- When you renew your CDL, all existing endorsements carry over automatically without retesting or additional fees.
- An endorsement is removed only if your license is suspended or revoked, or if you request removal from your state's DMV.
- If you fail to renew your CDL before it expires, you lose all endorsements and must retake the endorsement tests to restore them.
- Some endorsements (like hazmat) require periodic background checks or medical clearances that happen independently of the endorsement itself.
What Happens When Your CDL Expires and You Renew
When your commercial driver's license comes up for renewal, you return to your state's DMV with proof of identity, residency, and medical certification (if required). You pay the renewal fee and pass a vision test. Your endorsements do not require a separate renewal process — they straightforward transfer to your new license.
You will not retake the endorsement written test or the skills test for air brakes, doubles/triples, tanker, or any other endorsement you already hold. The DMV records show you passed those tests, and that record does not expire. The only exception is if your state has changed its endorsement requirements or testing procedures since you last tested, but even then, most states grandfather in existing endorsements.
If you let your CDL expire without renewing it, however, the situation changes. Once your license lapses, you lose all endorsements. To get them back, you will have to retake the written tests and skills tests for each endorsement you want to restore.
Hazmat Endorsements and Background Checks
The hazmat endorsement is the main exception to the "endorsements never expire" rule, though technically the endorsement itself does not expire — the security clearance behind it does. If you hold a hazmat endorsement, the Transportation Security Administration (TSA) conducts a background check as part of your initial process. That clearance is valid for five years.
When your five-year hazmat clearance expires, you must reapply for the endorsement. This means returning to your state's DMV, paying the hazmat endorsement fee again, and undergoing a new TSA background check. You will not retake the hazmat written test if you pass the background check — the test itself does not expire, only the security clearance does.
If your CDL expires before your hazmat clearance expires, your hazmat endorsement transfers to your renewed license. But if your hazmat clearance expires before your CDL expires, you lose the hazmat endorsement until you complete the reapplication and background check process.
Suspension, Revocation, and Loss of Endorsements
If your CDL is suspended or revoked, all endorsements are suspended or revoked along with it. You cannot drive under any endorsement during a suspension. Once the suspension is lifted and your license is restored, your endorsements return automatically — you do not have to retest or reapply.
Revocation is permanent loss. If your license is revoked, you lose all endorsements and must reapply for your CDL from the beginning, including retaking all endorsement tests, if you want to restore them. Revocation typically follows serious violations like driving under the influence or causing a fatal accident.
Some states also have rules about medical certification. If you fail to maintain the required medical certificate (which is separate from your license), your CDL may be downgraded or suspended, and your endorsements go with it. Renewing your medical certificate restores your endorsements.
Removing an Endorsement Voluntarily
You can ask your state's DMV to remove an endorsement from your license at any time. This is uncommon but happens when a driver no longer needs a particular endorsement or wants to simplify their license. To remove an endorsement, contact your state's DMV, provide your license number, and specify which endorsement you want removed. Most states allow this through a straightforward form or in-person request.
Removing an endorsement is different from letting it lapse. If you remove it voluntarily and later want it back, you will have to retake the written test and skills test for that endorsement, just as if you were earning it for the first time. There is no "grace period" to restore a voluntarily removed endorsement.
Restrictions and Waivers Are Also Permanent
Restrictions (like the air brake restriction, which limits you to vehicles without air brakes) and waivers (like an air brake waiver, which removes that restriction) follow the same rule as endorsements: they stay on your license until you remove them or your license is suspended or revoked.
If you have an air brake restriction and later pass the air brake test, you earn a waiver that removes the restriction. That waiver is permanent. If you have a waiver and want the restriction back (which is rare), you would have to request it from your DMV, and most states do not allow this — once you pass the test, the restriction is gone for good.
What to Do If You Are Unsure About Your Endorsements
If you are not certain which endorsements you hold or when they expire, check your physical license first — endorsements are printed on the back or in a designated section. You can also contact your state's DMV and provide your license number; they can tell you exactly which endorsements are active and when any clearances (like hazmat) are set to expire.
If you are planning to renew your CDL soon, start the process at least a month before your expiration date. Bring all required documents, including your medical certificate if your state requires one. Your endorsements will transfer automatically, and you will receive your renewed license with all endorsements intact.
Frequently Asked Questions
Do I have to retake endorsement tests when I renew my CDL?
No. Endorsement tests do not expire. When you renew your CDL, your endorsements transfer to your new license automatically. You only retake an endorsement test if you let your CDL lapse entirely, or if you voluntarily remove an endorsement and later want it back.
What happens to my hazmat endorsement when my CDL expires?
Your hazmat endorsement transfers to your renewed CDL automatically, as long as your TSA security clearance is still valid. The clearance lasts five years from the date you received it. If the clearance expires before your CDL does, you must reapply for the hazmat endorsement and pass a new background check.
Can I remove an endorsement and add it back later?
Yes, but you will have to retake the written test and skills test for that endorsement. Removing an endorsement is permanent until you retest. There is no way to straightforward restore a removed endorsement without passing the tests again.
If my CDL is suspended, do I lose my endorsements?
Your endorsements are suspended along with your license. You cannot use them while the suspension is in effect. Once your suspension is lifted and your license is restored, your endorsements return automatically — no retesting required.
What if I let my CDL expire without renewing it?
Once your CDL expires, you lose all endorsements. To restore them, you must renew your CDL and retake the endorsement tests for each endorsement you want back. The longer you wait to renew, the more you may have to study, since you will not have been driving under those endorsements.
