Endorsements appear as letters or codes printed on the front or back of your CDL card, depending on your state
When you earn a CDL endorsement, your state's licensing agency prints it directly onto your physical license card. Most states put endorsement codes on the back of the card in a section labeled "Endorsements" or "Restrictions," though some print them on the front. The exact location varies by state — there is no national standard for where endorsements live on the card itself.
Endorsements show up as single letters or short codes. For example, H means you can haul hazardous materials, T means you can operate double or triple trailers, and P means you can carry passengers. When you pass the endorsement test at your DMV or licensing office, the examiner updates your record, and your new card is printed with those letters added.
You cannot add endorsements to a card you already have — you have to request a replacement card from your state's licensing agency. This usually costs a small fee (typically $10 to $30, though amounts vary by state) and takes one to two weeks to arrive by mail.
Key Takeaways
- Endorsement codes appear as letters printed on your CDL card, most commonly on the back in a dedicated endorsements section.
- Each endorsement letter represents a specific privilege: H for hazmat, T for doubles/triples, P for passengers, and others depending on your state.
- You must pass a written test and sometimes a skills test at your DMV to earn an endorsement before it appears on your card.
- Getting an endorsement added to your card requires ordering a replacement card from your state licensing agency, which costs a fee and takes one to two weeks.
- Your current CDL card cannot be updated in place — the new card with endorsements printed on it replaces the old one entirely.
How endorsement codes are organized on the card
States organize endorsement codes in a standard section, though the layout differs slightly. Most cards have a line or box labeled "Endorsements" where all your earned codes appear together. If you have multiple endorsements — say, both H (hazmat) and T (doubles/triples) — they will all print on that same line or in that same box.
Some states also print restrictions near the endorsements. A restriction is the opposite: it is something you cannot do. For example, if you passed the air brake test but your truck has air brakes, you might have no restriction. But if you did not pass the air brake test, your card might show an "L" restriction, meaning you cannot operate vehicles with air brakes. Restrictions and endorsements live in the same area of the card so an officer or employer can see your full privileges and limitations at a glance.
The back of your CDL card is where most of this information lives. The front typically shows your photo, name, address, and license number. The back shows your class (A, B, or C), endorsements, restrictions, and other details like medical certification status.
Common CDL endorsement codes and what they mean
Here are the endorsements you are most likely to see on a CDL card:
- H — Hazardous Materials. You can transport hazmat cargo after passing a background check and the hazmat written test.
- T — Doubles/Triples. You can operate double or triple trailers after passing the doubles/triples written test.
- P — Passenger. You can transport passengers for hire after passing the passenger endorsement test.
- S — School Bus. You can drive a school bus after passing the school bus test and a background check.
- N — Tank Vehicle. You can haul liquids or gases in a tank trailer after passing the tank vehicle test.
- X — Combination of Hazmat and Tank. You have both H and N endorsements.
Some states add their own codes for endorsements not on this federal list. For example, a few states have endorsements for tow trucks, motorcycles, or other specialty vehicles. Your state's DMV handbook will list all available endorsements and what each one allows you to do.
What happens when you pass an endorsement test
When you pass an endorsement test at your DMV or licensing office, the examiner records the result in your driving record when ready. However, that does not mean the endorsement appears on your physical card right away. Your state's licensing agency has to print a new card with the endorsement code added, which takes time.
Most states mail your new card within one to two weeks. During that time, you may have a temporary paper permit or a notation in the system showing you have passed the test, but you should not rely on that as proof. Employers and law enforcement want to see the endorsement printed on your actual card. If you need to drive with that endorsement before your new card arrives, ask your DMV whether they issue a temporary document or whether you can use a printed confirmation of your test results.
Once your new card arrives, your old card is no longer valid for that endorsement. You should destroy the old card or return it to your DMV if they request it. Carrying both cards can cause confusion during a traffic stop or inspection.
Checking your endorsements before you receive your new card
If you want to verify that your endorsement was recorded before your new card arrives, you can check your driving record through your state's DMV website or by visiting a local office in person. Many states allow you to view your record online for free or a small fee. Your record will show all endorsements you have earned, even if your physical card has not been printed yet.
This is useful if you are starting a new job and your employer needs proof that you have the endorsement. You can print your driving record from the DMV website or request an official copy at a licensing office. Some employers will accept a printed record as temporary proof while they wait for your new card to arrive.
Replacing a lost or damaged CDL card with endorsements
If your CDL card is lost, stolen, or damaged, you need to order a replacement from your state's licensing agency. The replacement card will include all endorsements that were on your original card — you do not have to retake the endorsement tests. The DMV pulls your record and prints a new card with everything you had before.
Replacement cards usually cost the same as a new endorsement card (typically $10 to $30) and take one to two weeks to arrive. Some states offer expedited printing for an extra fee if you need the card sooner. Contact your state's DMV to find out whether expedited service is available and what it costs.
How to read your endorsements during a traffic stop or inspection
If you are pulled over or stopped for a roadside inspection, an officer or inspector will look at the endorsements section on the back of your card to see what you are authorized to haul or do. They are checking that your cargo or operation matches your endorsements. For example, if you are carrying hazmat but your card does not show an H endorsement, that is a violation.
Make sure you know what endorsements are on your card before you start a job. If your employer asks you to haul something that requires an endorsement you do not have, you cannot legally do it — even if your employer says it is okay. The endorsement must be printed on your card.
Frequently Asked Questions
Can I drive with an endorsement before my new card arrives?
That depends on your state. Some states issue a temporary paper permit or letter confirming you passed the test. Others do not. Contact your DMV to ask whether you can drive with the endorsement while waiting for your new card, or whether you need to wait until the card arrives. Do not assume — an officer may not accept a temporary document as proof.
What if I see an endorsement on my card that I did not earn?
Contact your state's DMV when ready. Errors on your license are rare but do happen. Bring your card and any test records you have. The DMV can investigate and issue a corrected card if the endorsement was added by mistake.
Do I need to renew my endorsements when I renew my CDL?
No. Endorsements do not expire separately from your CDL. When you renew your license, all your endorsements renew with it. However, some endorsements like hazmat require a background check every time you renew, so you may need to pass a background check again even if you do not retake the written test.
Can I have endorsements from different states on one card?
No. Your CDL is issued by one state only, and endorsements appear only on that state's card. If you move to a new state, you will need to transfer your CDL to that state's licensing agency. The new state will recognize your endorsements from your old card and print them on your new one.
What if my job requires an endorsement I do not have yet?
You will need to study for and pass the written test for that endorsement at your state's DMV. Some endorsements also require a skills test or background check. Once you pass, order your replacement card. Plan for one to two weeks for the card to arrive before you can legally use that endorsement on the job.
