If you hold a commercial driver's license — or you're working toward one — your endorsements are just as important as the license class itself. They determine what you're legally permitted to haul, tow, or operate. Knowing exactly which endorsements are currently on your license, and how to verify them, is a practical necessity for staying compliant on the road.
An endorsement is an authorization added to a driver's license that permits the holder to operate a specific type of vehicle or transport a specific type of cargo beyond what the base license class allows.
For commercial drivers, endorsements are federally defined categories — though testing and issuance are handled at the state level. The most common CDL endorsements include:
| Endorsement Code | What It Covers |
|---|---|
| H | Hazardous materials (HazMat) |
| N | Tank vehicles |
| P | Passenger vehicles (buses) |
| S | School buses |
| T | Double/triple trailers |
| X | Combination of tank + HazMat |
Non-commercial licenses can carry endorsements too — motorcycle operation is the most common example — but the CDL endorsement system is the most structured and most consequential. Operating a vehicle that requires an endorsement without holding one is a federal violation.
Your endorsements are printed directly on your physical driver's license, typically on the front. Look for a field labeled "Endorsements" or "Endors." It will display the corresponding letter codes. If that field reads "NONE" or is blank, no endorsements are currently active on your license.
Your endorsements are also recorded in your driving record — the official document maintained by your state's motor vehicle agency. This is the authoritative source, and it's what employers, carriers, and law enforcement reference. The physical card reflects what's in the record, but the record itself is the legal document.
There are several ways to verify which endorsements are currently on your license:
1. Look at your physical license The fastest check. Find the endorsement field and note the codes. Keep in mind that a license can expire or endorsements can lapse — the physical card shows what was issued, not necessarily what's currently valid.
2. Request your driving record Your state's motor vehicle agency maintains your full driving record, which includes your current license class, active endorsements, any restrictions, and your driving history. Most states allow you to request this:
There is typically a fee for obtaining an official record, though the amount varies by state and record type.
3. Use the CDLIS (for CDL holders) The Commercial Driver's License Information System (CDLIS) is a federally maintained database administered by the American Association of Motor Vehicle Administrators (AAMVA). It consolidates CDL records across all states, which matters because commercial drivers are prohibited from holding licenses in more than one state. Your employer or a background screening company may access CDLIS directly, but individual drivers generally access their CDL record through their state DMV.
4. Check through your employer or carrier Many trucking companies and fleet operators run Motor Vehicle Reports (MVRs) on drivers periodically. If you're currently employed, your employer may already have a recent record on file. This isn't a substitute for your own copy, but it's another data point.
An endorsement doesn't necessarily stay active for the life of your license. Several situations can affect endorsement validity:
🔍 Endorsements that appear on an expired license are not valid. The expiration date on your license applies to the entire credential, endorsements included.
The process of checking your endorsements — and what you'll find — depends on factors specific to your situation:
Your physical license is a snapshot. It reflects what was issued at the time of printing — not what may have changed since. Endorsements can be added, removed, or lapsed between renewal cycles without any visible change to the card in your wallet.
Your official driving record is the only real-time source of truth. How current that record is, how you access it, and what it costs to obtain depends entirely on your state — and that's the piece only your state's motor vehicle agency can answer.
