Read the class code on the front of your license

Your driver's license lists a class code — usually a single letter or number — that tells you what vehicles you're legally permitted to drive. In most states, this appears in the upper right corner or along the left edge of the card. The code itself is small, but it's the clearest way to know exactly what you hold.

The class code is not the same as your license number. It's a separate designation that changes based on the vehicle type and weight. If you can't find it on your card, check your state's DMV website — they can tell you where it appears on licenses issued in your state, since placement varies.

Key Takeaways

  • Your license class code appears on the physical card itself and tells you which vehicle types you can legally drive.
  • Class D or C licenses cover standard passenger cars and light trucks, while Class B covers larger vehicles like delivery trucks or small buses.
  • Class A licenses are for tractor-trailers and require a separate commercial endorsement test.
  • Restrictions printed on your license — such as corrective lenses or automatic transmission only — limit how you can drive even within your class.

Standard passenger vehicle licenses (Class D or C)

Most people hold a Class D license in states that use that designation, or a Class C license in others. Both cover the same vehicles: standard passenger cars, pickup trucks under a certain weight, and small SUVs. The weight threshold varies by state — typically between 10,000 and 26,000 pounds gross vehicle weight rating (GVWR).

If your license shows Class D or C with no additional codes or endorsements, you can drive any passenger vehicle that falls within that weight limit. You cannot legally drive a full-size moving truck, a school bus, or a vehicle designed to carry more than a certain number of passengers, even if you feel capable of doing so.

Commercial licenses for larger vehicles (Class A and B)

A Class B license allows you to drive larger vehicles that exceed the weight limit for Class D or C — typically delivery trucks, small buses, or RVs above a certain size. You still cannot drive a tractor-trailer combination. Class B requires a written test beyond the standard license exam, and some states require a brief driving test as well.

A Class A license is required to drive tractor-trailers and other heavy combination vehicles. This is a commercial driver's license (CDL), and it requires passing a written knowledge test, a skills test, and a medical examination. You cannot hold a Class A license without also passing a CDL-specific exam — it's not an upgrade you can add to a regular license.

Endorsements and restrictions that modify your license

Beyond the class code, your license may show endorsements — additional permissions — or restrictions — limitations on how you can drive. Endorsements appear as letter codes (such as "H" for hazardous materials or "P" for passenger vehicles) and mean you've passed an extra test for that privilege. Restrictions appear as codes or written notes (such as "corrective lenses required" or "automatic transmission only") and are mandatory conditions of your license.

A restriction means you cannot legally drive without meeting that condition. If your license says "corrective lenses," you must wear glasses or contacts every time you drive. If it says "automatic transmission only," you cannot drive a manual transmission vehicle, even if you know how. Violating a restriction can result in a ticket and points on your record.

How to find your specific state's class codes

Class codes are not standardized across states. A Class D in one state may not exist in another, and the vehicles covered by each class vary slightly. The most reliable way to understand your specific license is to visit your state's DMV website and search for "driver's license classes" or "license classifications."

Your state's DMV site will show a chart listing each class code, the vehicles it covers, the weight limits, and what tests are required. You can also call your state's DMV directly — they can tell you over the phone what your class code permits. Keep this information handy if you ever need to rent a vehicle or explain your license to an employer.

What happens if you drive a vehicle your license doesn't cover

Driving a vehicle outside your license class is illegal, even if you own it or have permission from the owner. If you're stopped while driving a vehicle your license doesn't permit, you can be cited for driving without proper credentials. This is different from driving without a license — it's a separate violation that can result in fines and points on your record.

If you need to drive a vehicle outside your current class, you must first obtain the appropriate license class. This typically requires passing a written test and sometimes a driving test. The process takes a few weeks in most states, so plan ahead if you know you'll need a different class for work or personal reasons.

Frequently Asked Questions

What does it mean if my license says "CDL" on it?

CDL stands for commercial driver's license, which is a Class A or sometimes Class B license. It means you've passed the commercial licensing tests and can legally drive heavy trucks or buses for work. A CDL comes with additional medical certification requirements and stricter rules about violations.

Can I drive a rental truck with my regular Class D license?

It depends on the truck's weight. If the rental truck's gross vehicle weight rating is under your state's threshold for Class D (usually 10,000 to 26,000 pounds), you can drive it. If it's heavier, you cannot legally drive it without a Class B license. Call the rental company and ask the GVWR before you reserve.

What if I have a restriction I don't think I need anymore?

You can request a restriction be removed by visiting your state's DMV office. Some restrictions, like corrective lenses, can only be removed if you pass a vision test. Others may require a medical exam or a driving test. Contact your DMV to learn what's required for your specific restriction.

Does my license class change when I renew?

Not automatically. Your class stays the same unless you request a change or fail to meet the requirements (such as a medical certification for a CDL). When you renew, your new card will show the same class unless you've taken additional tests or your state has changed its classification system.
