A standard driver license is Class D in most states, and it covers cars, small trucks, and motorcycles under 50cc

The class of driver license you receive depends on what you applied for and what vehicle you want to drive. In most states, a regular passenger vehicle license is called Class D (sometimes Class C). This is the license most people get when they pass their driving test, and it covers sedans, SUVs, pickup trucks up to a certain weight, and in some states, motorcycles under 50 cubic centimeters.

The class system exists because different vehicles require different skills and training. A heavy truck needs more braking distance and different handling than a car. A motorcycle has no protective frame. States use license classes to make sure drivers have trained for the specific vehicle they operate. When you take your test, you choose which class you want — the examiner tests you on that vehicle type.

Your license paperwork will show your class clearly. It is usually printed as "Class D" or "Class C" near the top or bottom of the card. Some states also list restrictions or endorsements on the same line — for example, "Class D, no motorcycle" or "Class D with air brake restriction." These notes tell you exactly what you can and cannot drive legally.

Key Takeaways

  • Class D (or Class C in some states) is the standard license for cars, SUVs, and light trucks, and it is what most people receive after passing a driving test.
  • Motorcycles, commercial trucks, and buses require different license classes — usually Class M for motorcycles and Class A or B for commercial vehicles.
  • Your license card shows your class and any restrictions, so you can check what you are legally permitted to drive.
  • If you want to drive a vehicle outside your license class, you must take a separate test and pay a fee to upgrade or add an endorsement.
  • Driving a vehicle you are not licensed for is illegal and can result in fines, points on your record, and vehicle impoundment.

How license classes differ by vehicle type

Most states use a letter system to sort licenses by what the driver can operate. Class D covers standard passenger cars and light trucks — typically vehicles under 26,000 pounds gross vehicle weight rating (GVWR). This is the broadest and most common class.

Class M or Motorcycle is separate and requires its own test. You cannot legally ride a motorcycle on a Class D license, even if you have driven cars for decades. The test covers balance, braking, and handling unique to two wheels. Some states allow you to add a motorcycle endorsement to your Class D instead of getting a separate card.

Class A and Class B are commercial licenses for trucks, buses, and vehicles carrying hazardous materials. Class A covers the heaviest vehicles (over 26,000 pounds) and is required to drive semi-trucks or large buses. Class B covers medium trucks. Both require a commercial driving record check, medical certification, and a written and practical test more rigorous than the Class D exam. You must be at least 18 or 21 depending on the state and the type of cargo.

Some states have additional classes — Class E for vehicles towing trailers over a certain weight, or Class F for farm vehicles. Check your state's motor vehicle handbook to see the full list.

What you can and cannot drive on a Class D license

On a Class D license, you can drive any passenger car, station wagon, SUV, or pickup truck under the weight limit set by your state. You can also tow a trailer, but usually only up to a certain combined weight — often 10,000 pounds or less. Your license card or the state handbook will specify the exact limit.

You cannot drive a motorcycle, even a small one, unless your license explicitly says you can. You cannot drive a commercial truck, a bus carrying passengers for hire, or any vehicle requiring hazmat placards. You cannot drive a vehicle over the weight limit for your class. Doing any of these is illegal, and police can cite you, impound the vehicle, and add points to your driving record.

Some Class D licenses come with restrictions noted on the card — for example, "corrective lenses required" or "automatic transmission only." These restrictions are tied to your medical exam or test performance. You must follow them. Driving without the required glasses or in a manual transmission car when your license says automatic only is a violation.

How to upgrade or add a license class

If you want to drive a vehicle outside your current class, you must take a test for that class. For a motorcycle endorsement, you typically take a written test on motorcycle safety and a practical riding test. The fee is usually $10 to $50. Some states offer a waiver of the practical test if you complete an approved motorcycle safety course.

For a commercial license upgrade (Class A or B), the process is longer. You must pass a written exam on commercial vehicle operation, air brakes, and hazmat rules (if applicable). You must also pass a practical driving test in a vehicle of that class. You will need a medical certificate from a Department of Transportation–approved doctor. The whole process can take several weeks and cost $100 to $300 depending on the state.

You do not need to retake your Class D test to add a motorcycle endorsement or upgrade to a commercial class. The new test is separate and only covers the new vehicle type. However, if you let your license expire, you may have to retake the Class D test as well when you renew.

Restrictions and endorsements on your license

Beyond the main class, your license may carry restrictions or endorsements. A restriction is something you must do or must not do — corrective lenses, hearing aid, automatic transmission only, or no motorcycle. An endorsement is permission to do something beyond your base class — a motorcycle endorsement, a hazmat endorsement, or a passenger endorsement for buses.

Restrictions are usually added because of your medical exam or test performance. If you failed the practical test in a manual transmission car but passed in an automatic, the examiner may restrict you to automatic only. If you wear glasses, the examiner will note that you must wear them while driving.

Endorsements are added when you pass an additional test. A hazmat endorsement, for example, requires a separate written test and a background check. A passenger endorsement (for driving a bus with more than 15 passengers) requires a practical test in a bus. You can have multiple endorsements on one license.

What happens if you drive without the right license class

Driving a vehicle you are not licensed for is a traffic violation in every state. The penalty varies but typically includes a fine of $100 to $500, points added to your driving record, and possible vehicle impoundment. If you cause an accident while driving without the proper license, your insurance may deny the claim, leaving you liable for all damages.

A second or third violation can lead to license suspension. Driving with a suspended license is a criminal offense in most states and can result in jail time, a larger fine, and a longer suspension. It also makes it harder to get hired for jobs that require a clean driving record.

If you are unsure whether your license covers a vehicle you want to drive, check your state's motor vehicle handbook or call your local DMV. It is faster and cheaper to ask than to risk a citation.

How to check your license class

Your license class is printed on the front or back of your driver license card. Look for a line that says "Class" followed by a letter (D, M, A, B, etc.). Below or next to it, you will see any restrictions or endorsements listed as codes or full words.

If you cannot read your card clearly or you are not sure what a code means, your state's motor vehicle handbook has a key. You can also visit your state's DMV website or call the local office. Many states now let you check your license status and restrictions online through a portal.

If your license is damaged or you believe the class is wrong, you can request a replacement card at your local DMV. There is usually a small fee ($5 to $15), and the new card arrives in one to two weeks.

Frequently Asked Questions

Can I drive a motorcycle with a Class D license?

No. A motorcycle requires a separate Class M license or a motorcycle endorsement added to your Class D. Riding a motorcycle on a Class D license is illegal, even if you are an experienced car driver. You must pass a written and practical test on a motorcycle to get the endorsement.

What is the weight limit for a Class D license?

Most states set the limit at 26,000 pounds gross vehicle weight rating (GVWR). This covers nearly all passenger cars, SUVs, and pickup trucks. Your state's motor vehicle handbook lists the exact limit. If you are unsure whether a specific truck falls under the limit, check the vehicle's door jamb or owner manual for the GVWR.

Do I need a different license to tow a trailer?

Not usually. A Class D license covers towing a trailer up to a certain combined weight — often 10,000 pounds or less. If you want to tow heavier trailers, you may need a Class E license or a special endorsement. Check your state's rules or ask at the DMV.

What if my license says Class D with restrictions?

Restrictions are conditions you must follow while driving. Common ones are corrective lenses (you must wear glasses), automatic transmission only, or no motorcycle. Violating a restriction is a traffic violation. If your restriction no longer applies (for example, you had eye surgery), you can request a new license without the restriction at your local DMV.

How do I upgrade from Class D to Class A?

You must pass a written exam on commercial vehicle operation and a practical driving test in a Class A truck. You will also need a Department of Transportation medical certificate. The process takes several weeks and costs $100 to $300. Some states require you to hold a Class D license for a minimum time before upgrading.
