The class on your driver’s license is printed on the front of the card, usually right next to the word “Class” or the abbreviation “CL,” and that single letter or number tells you which vehicles you’re legally allowed to drive. If you’re wondering what class driver’s license you have, most people carry a standard non-commercial license, labeled Class C, D, or E depending on the state, which covers regular passenger cars and light trucks. The letter itself matters less than the category of vehicle it authorizes and the endorsements or restrictions that sit alongside it.
Where to Find the Class on Your Card
Every U.S. driver’s license follows a standardized layout set by the American Association of Motor Vehicle Administrators. Your vehicle classification appears on the front of the card in what the standard calls “Zone II,” the same area that holds your endorsements and restrictions.1AAMVA. 2025 AAMVA DL/ID Card Design Standard On most cards it sits near the top-right, close to your photo or expiration date. The class is a single letter (C, D, M, and so on) or occasionally a number.
If letter codes you don’t recognize appear next to the class, flip the card over. The back (Zone IV) is required to include explanations of any codes used on the front, including endorsement and restriction abbreviations. That legend saves you a call to the DMV.
What a Standard Non-Commercial Class Covers
The license most drivers carry authorizes you to operate ordinary passenger vehicles: sedans, SUVs, minivans, and light pickup trucks. States assign different letters to this same basic privilege. Some call it Class D, others use Class C or Class E. The practical effect is identical. You can drive personal vehicles that don’t exceed the commercial weight threshold.
That threshold is where things get concrete. Federal regulations define a commercial motor vehicle as one with a gross vehicle weight rating of 26,001 pounds or more.2eCFR. 49 CFR 383.91 – Commercial Motor Vehicle Groups If the vehicle you’re driving stays below that line, and you’re not hauling hazardous materials or carrying 16 or more passengers, your standard license covers it. That includes towing a small trailer, as long as the combined weight stays under the commercial threshold.
So if your card shows Class C, D, or E and nothing says “commercial,” you have a standard non-commercial license. You passed a written knowledge test and a road skills test to get it, and you’re authorized for ordinary personal driving.
What Class A, B, or C Mean on a CDL
If your card shows Class A, Class B, or Class C with a “commercial” designation, you hold a commercial driver’s license, and the letter dictates the heaviest equipment you can operate. Federal regulations split commercial vehicles into three groups by weight and configuration.2eCFR. 49 CFR 383.91 – Commercial Motor Vehicle Groups
- Class A (Combination Vehicle): any combination of vehicles with a gross combination weight rating of 26,001 pounds or more, where the towed unit weighs more than 10,000 pounds. Tractor-trailers and most semi-truck setups sit here.
- Class B (Heavy Straight Vehicle): a single vehicle weighing 26,001 pounds or more, or one towing a unit that does not exceed 10,000 pounds. Large buses, dump trucks, and box trucks fall into this group.
- Class C (Small Commercial Vehicle): a vehicle that doesn’t meet the Class A or Class B weight definitions but is either designed to carry 16 or more passengers (including the driver) or used to transport placarded hazardous materials.
A Class A holder can generally drive Class B and Class C vehicles too. The reverse doesn’t apply. Driving a commercial vehicle without the correct class is treated as a serious traffic violation: a second conviction within three years brings a 60-day disqualification from operating any commercial vehicle, and a third within three years extends that to 120 days.3eCFR. 49 CFR 383.51 – Disqualification of Drivers
One point of confusion worth flagging: non-commercial Class C and commercial Class C are not the same thing. The commercial version is tied to passenger capacity or hazmat placards. The non-commercial version is just the everyday car license some states happen to label with that letter.
Endorsement Letters Next to Your Class
Your CDL class tells you the weight and type of vehicle you can drive. Endorsements unlock specific kinds of cargo or passenger operations and appear as additional letter codes on your card. Each requires a separate knowledge test, and some add a skills test.4eCFR. 49 CFR 383.93 – Endorsements
- H (Hazardous Materials): required to haul loads that need hazmat placards. Involves a knowledge test and a TSA security threat assessment.
- N (Tank Vehicle): required for operating tank vehicles. Knowledge test only.
- P (Passenger): required when driving a vehicle designed to carry 16 or more passengers. Knowledge and skills test.
- S (School Bus): required specifically for school bus operation. Knowledge and skills test.
- T (Double/Triple Trailers): required for pulling double or triple trailer combinations. Knowledge test only.
- X (Hazmat + Tank): a combined endorsement for drivers who haul hazardous materials in tank vehicles.
Driving without the correct endorsement carries the same disqualification penalties as driving the wrong class, and employers are prohibited from knowingly letting a driver operate a commercial vehicle without the right endorsements.3eCFR. 49 CFR 383.51 – Disqualification of Drivers
Restriction Codes on Your License
Alongside your class and endorsements, your card may show restriction codes that limit how or when you can drive. These come from your skills test, a medical evaluation, or the type of vehicle you tested in. Common ones include:
- Corrective lenses: you must wear glasses or contacts while driving. Often coded “B” or a numeric code depending on the state.
- Automatic transmission only: if you tested in an automatic, some states bar you from driving a manual.
- No air brakes: CDL holders who didn’t test on air brake-equipped vehicles get a restriction barring them from operating vehicles with air brakes.
- Daylight driving only: applied when a medical evaluation shows impaired night vision.
Violating a restriction carries the same weight as driving outside your license class. If your card says corrective lenses and you’re pulled over without them, expect a citation. The legend on the back of the card spells out what each code means.
Class M and Other Two- and Three-Wheel Designations
Two-wheeled vehicles need separate authorization because they handle differently from cars. Most states use Class M or add an “M” endorsement to your existing license. Earning it requires a motorcycle-specific knowledge test and a riding skills test, or completion of an approved rider safety course that waives the skills test. Costs vary widely by state, running from around $10 to $300 once you factor in testing and course fees.
Mopeds sit in a narrower category. States generally restrict moped-class vehicles to lower maximum speeds (often around 30 mph) and smaller engines (typically 50cc or less). Some states let you ride a moped on a standard license; others require a separate moped permit. Riding a motorcycle without the proper endorsement can bring a citation and possible vehicle impoundment.
Autocycles are three-wheeled enclosed vehicles with a steering wheel and pedals rather than handlebars. Most states that have addressed them allow operation on a standard non-commercial license without a motorcycle endorsement, though you’ll want to confirm your state’s specific classification.
How to Check Your Class if You Don’t Have the Card
If your physical card is lost, damaged, or you just want to confirm what’s on your record, most states offer an online portal through their Department of Motor Vehicles. You’ll generally need your license number, date of birth, and sometimes your Social Security number to pull up your record.
Once logged in, look for a section labeled “driving record” or “license status.” It will show your current class, active endorsements, any restrictions, and whether your license is in good standing. Fees for pulling your own record vary by state, and some states let you view basic status information at no charge. Many portals also let you download or print your driving record, which works as documentation if you need to prove your class to an employer or insurer while a replacement card is in the mail.
