What Each Driver's License Type Covers

Every state issues multiple classes of driver's licenses, and the class you hold determines what vehicles you can legally operate. The main types are Class D (standard passenger vehicle), Class C (commercial vehicles), and Class M (motorcycles), though some states use different letters or names. Within each class, you may also hold endorsements — special permissions added to your license — and restrictions — limitations on when or how you can drive.

The specific class names and what they cover vary by state. A Class D license in New York is not identical to a Class D in California. This guide explains the main categories used across most states, the vehicles each permits, and how to know which type you need. Your state's DMV website will have the exact definitions for your location.

Key Takeaways

  • Class D (or equivalent) is the standard license for driving passenger cars, vans, and light trucks under a certain weight threshold.
  • Class C (or equivalent) is required to operate commercial vehicles over a certain weight, including semi-trucks and large buses.
  • Class M (or equivalent) is required to operate any motorcycle, moped, or motorized two-wheeled vehicle.
  • Endorsements are added permissions — such as the air brake endorsement or hazmat endorsement — that expand what you can drive with your base license class.
  • Restrictions limit your driving — such as corrective lenses required, no night driving, or automatic transmission only — and appear on your license card.

Class D: Standard Passenger Vehicle License

A Class D license (sometimes called Class 5 in some states, or straightforward a "regular" or "passenger" license) is the most common type. It permits you to drive passenger cars, vans, pickup trucks, and small utility vehicles up to a certain weight limit. The weight threshold varies by state — typically between 10,000 and 26,000 pounds Gross Vehicle Weight Rating (GVWR). Anything heavier requires a commercial license.

Class D is what most people obtain at age 16 or 17 when they first learn to drive. It is the default license for everyday driving: commuting, errands, family trips. You do not need any special training or endorsement to hold a Class D license, though you must pass a written knowledge test and a driving skills test. Most states require you to hold a learner's permit for a set period (often 6 months to 1 year) before you can test for a full Class D license.

A Class D license does not permit you to drive a school bus, a vehicle carrying hazardous materials, or any commercial vehicle — even if you own it. If you want to drive a vehicle heavier than the Class D threshold, you must obtain a commercial license.

Class C: Commercial Vehicle License

A Class C license (called a Commercial Driver's License or CDL in most states) is required to operate any vehicle over the GVWR threshold set by your state, or any vehicle designed to carry 16 or more passengers (including the driver). This includes semi-trucks, large buses, dump trucks, tanker trucks, and tractor-trailers. Some states also require a CDL to drive certain smaller commercial vehicles, depending on the vehicle's design and intended use.

Obtaining a Class C license is more involved than a Class D. You must be at least 18 years old (21 in some states for interstate driving), pass a medical examination, hold a valid Class D license, and pass both a written knowledge test and a skills test specific to commercial vehicles. Many states require you to hold a Commercial Learner's Permit (CLP) for at least 7 days before you can test for the full CDL. You may also need to complete a training course at a truck driving school, though this is not always mandatory.

A Class C license comes with endorsements you must earn separately. The most common are the air brake endorsement (required if the vehicle has air brakes), the hazmat endorsement (required to carry hazardous materials), and the tanker endorsement (required to carry liquids in bulk). Each endorsement requires an additional written test. You may also have restrictions placed on your CDL — for example, "no hazmat" if you did not pass the hazmat test, or "automatic transmission only" if you took your skills test in an automatic truck.

Class M: Motorcycle License

A Class M license (sometimes called a motorcycle endorsement or motorcycle license) is required to operate any motorcycle, motorized scooter, or moped. The exact definition of what counts as a motorcycle varies by state — some states set a minimum engine size (often 50cc) below which you do not need a Class M, while others require it for any two-wheeled motorized vehicle.

To obtain a Class M license, you must be at least 16 or 17 years old (age varies by state) and pass a motorcycle-specific knowledge test and skills test. Many states offer a Motorcycle Safety Course that, if completed, waives the riding skills test and sometimes the knowledge test. These courses typically run 4 to 8 hours and teach basic motorcycle operation, safety, and road awareness. Taking the course is not mandatory in most states, but it is the fastest and safest route to a Class M license.

You can hold a Class M license alongside a Class D license — they are separate credentials. Some states issue a Class M as an endorsement on your Class D license (printed as "M" on the card), while others issue it as a separate card. Either way, you can legally ride a motorcycle and drive a car with the same license document or pair of documents.

Endorsements: Additional Permissions on Your License

An endorsement is a special permission added to your license that expands what you are allowed to drive. Endorsements appear as letters or codes on your license card. You do not automatically receive endorsements — you must request them, meet any age or training requirements, and pass the required test.

Common endorsements include:

  • Air Brake (A) — Required in most states to operate a vehicle with air brakes. You must pass a written test on air brake systems.
  • Hazmat (H) — Required to transport hazardous materials. You must pass a written test and pass a federal background check.
  • Tanker (N) — Required to transport liquids or gases in bulk. You must pass a written test on tanker-specific safety rules.
  • Passenger (P) — Required in some states to operate a vehicle designed to carry 16 or more passengers. You must pass a written test.
  • School Bus (S) — Required to drive a school bus. You must pass a written test and a skills test, and meet background check requirements.
  • Motorcycle (M) — Permits you to ride a motorcycle. You must pass a motorcycle knowledge test and skills test, or complete a safety course.

You can hold multiple endorsements on a single license. For example, a truck driver might hold a Class C license with air brake, hazmat, and tanker endorsements. Each endorsement requires a separate test, and you must renew them when your license renews.

Restrictions: Limitations on Your Driving Privileges

A restriction is a limitation placed on your license that specifies when, where, or how you can drive. Restrictions appear as codes on your license card and are legally binding — driving in violation of a restriction can result in a ticket. Unlike endorsements, you do not request restrictions; they are imposed by the DMV based on your test results, medical condition, or age.

Common restrictions include:

  • Corrective Lenses (1) — You must wear glasses or contact lenses whenever you drive. This is the most common restriction.
  • Automatic Transmission Only (10) — You may only drive vehicles with automatic transmissions. This is often placed on drivers who took their skills test in an automatic vehicle.
  • No Night Driving (11) — You may not drive between sunset and sunrise. This is sometimes placed on very young drivers or drivers with vision problems.
  • No Freeway Driving (12) — You may not drive on interstate highways. This is sometimes placed on young drivers during a learner's permit phase.
  • Hearing Aid Required (13) — You must wear a hearing aid while driving if you have significant hearing loss.
  • Daylight Only (14) — You may only drive during daylight hours.

Restrictions are not permanent. As you age or if your medical condition improves, you can request that a restriction be removed. You must contact your state DMV and may need to pass a new test or provide medical documentation to have the restriction lifted.

Learner's Permits and Provisional Licenses

Before you can obtain a full Class D or Class M license, most states require you to hold a learner's permit (sometimes called a learner's license or instruction permit) for a set period. A learner's permit allows you to drive under supervision — usually with a licensed adult in the vehicle — so you can practice before taking your skills test.

To obtain a learner's permit, you must be at least 15 or 16 years old (age varies by state), pass a written knowledge test, and pass a vision and hearing screening. You do not need to pass a driving skills test. A learner's permit is typically valid for 6 months to 1 year, and you must renew it if you do not pass your skills test before it expires.

Some states also issue provisional licenses (sometimes called intermediate licenses) to young drivers who have passed their skills test but are under 18. A provisional license has more restrictions than a full license — for example, no driving between 11 p.m. and 5 a.m., or no passengers under 20 years old. These restrictions are designed to reduce accidents among young drivers. Provisional licenses typically convert to full licenses when you turn 18.

Frequently Asked Questions

Can I drive a pickup truck with a Class D license?

Yes, if the truck's GVWR is below your state's threshold — usually 10,000 to 26,000 pounds. Most personal pickup trucks fall below this limit. Check your truck's registration or owner's manual for the GVWR. If it exceeds your state's limit, you need a Class C license.

Do I need a separate license for a motorcycle, or is it an endorsement?

It depends on your state. Some states issue a Class M as a separate license card, while others print it as an endorsement (M) on your Class D license. Either way, you can legally ride a motorcycle. Check your state DMV website to see which format your state uses.

What is the difference between an endorsement and a restriction?

An endorsement is a permission you request that expands what you can drive — like a hazmat endorsement. A restriction is a limitation placed on your license that limits when or how you can drive — like corrective lenses required. Endorsements are optional; restrictions are mandatory.

Can I get a Class C license without attending truck driving school?

Yes, in most states. You do not need to attend a truck driving school to obtain a CDL, though you must pass a written knowledge test and a skills test. Many people attend school because it improves their chances of passing the skills test and makes them more employable, but it is not a legal requirement.

What happens if I drive a vehicle I am not licensed for?

You can be cited for driving without the proper license class. The penalty varies by state but typically includes a fine, points on your driving record, and possible license suspension. For example, driving a semi-truck with only a Class D license is a serious violation.
