The main license classes and what they let you drive
Every state issues driver's licenses in different classes, and each class permits you to operate a specific category of vehicle. The class printed on your license determines what you're legally allowed to drive — driving something outside your class can result in a ticket, even if you know how to operate it. Most people hold a Class D (or Class C in some states), which covers standard passenger cars, pickup trucks, and small vans. Heavier vehicles, motorcycles, and commercial trucks require different classes.
The exact names and rules vary by state. A Class D in New York is not identical to a Class D in Texas. What matters is understanding what your state's system means and whether the class you hold matches what you actually drive.
Key Takeaways
- Class D (or C) is the standard license for cars, pickup trucks, and small vans — the one most people hold.
- Class M is required to operate any motorcycle, including mopeds and scooters, and usually requires a separate test.
- Commercial Driver's License (CDL) classes — A, B, and C — are needed for trucks over a certain weight and are issued only after medical certification and a written and skills test.
- Passenger vehicle endorsements like P (passenger van) or S (school bus) add permissions to your base class but require additional testing.
- Your state's DMV website lists the exact weight thresholds and vehicle types for each class, since these differ across states.
Class D: The standard passenger vehicle license
Class D (called Class C in some states) is the most common license and covers what most people drive every day. It permits you to operate passenger cars, pickup trucks up to a certain weight, vans designed to carry up to 15 passengers, and small utility vehicles. The weight limit varies — typically between 10,000 and 26,000 pounds depending on your state — so check your state's DMV handbook to know the exact threshold.
You obtain a Class D by passing a written test on traffic laws and road signs, a vision test, and a behind-the-wheel driving test. Most people get this license as teenagers or young adults. Renewal is straightforward: you renew by mail or online in most states, though some require an in-person visit every few years.
Class M: Motorcycle and motorized two-wheeler license
Class M is required to legally operate a motorcycle, motorized scooter, or moped on public roads. Some states include three-wheeled motorcycles (trikes) under Class M; others have a separate class for them. The rules are strict: you cannot legally ride a motorcycle with only a Class D license, even if you own the bike.
Getting a Class M usually requires passing a separate written test focused on motorcycle-specific hazards and handling, a vision test, and a skills test on an actual motorcycle. Many states offer a Motorcycle Safety Foundation (MSF) course that, if completed, waives the skills test. The course typically takes one or two days and covers basic operation, braking, turning, and emergency maneuvers. Some states also allow you to add a motorcycle endorsement (usually marked "M") to an existing Class D license instead of obtaining a separate license.
Commercial Driver's License (CDL) classes A, B, and C
A Commercial Driver's License is required if you operate a truck or bus for work and the vehicle exceeds a certain weight threshold. Most states use 26,001 pounds as the cutoff — any vehicle heavier than that requires a CDL. The three CDL classes determine what size and type of commercial vehicle you can drive.
Class A CDL covers the largest trucks, including tractor-trailers (semi-trucks) and any combination of vehicles totaling more than 26,001 pounds where the towed unit weighs more than 10,000 pounds. Class B CDL covers single commercial vehicles over 26,001 pounds that are not tractor-trailers — typically straight trucks like dump trucks, cement mixers, or delivery trucks. Class C CDL covers smaller commercial vehicles or any vehicle carrying hazardous materials or 16 or more passengers, even if the vehicle weighs less than 26,001 pounds.
Obtaining a CDL is more involved than a standard license. You must pass a medical examination (DOT physical), a written test specific to your class, and a skills test that includes a pre-trip vehicle inspection, a backing maneuver, and an on-road driving test. The process typically takes several weeks. You also must hold a valid Class D license before you can get a CDL.
Endorsements and restrictions that modify your license
An endorsement is a notation on your license that adds a specific permission to your base class. For example, a P endorsement allows you to drive a passenger van; an S endorsement allows you to drive a school bus; an H endorsement allows you to haul hazardous materials. Each endorsement requires passing an additional written test and sometimes a skills test. You do not receive a separate license card — the endorsement is printed on your existing license.
A restriction is the opposite: it limits what you can do with your license. Common restrictions include corrective lenses (you must wear glasses or contacts), automatic transmission only (you cannot drive a manual), or daylight driving only (you cannot drive at night). Restrictions are also printed on your license card and are legally binding.
How to find your state's specific license classes
Because each state designs its own system, the exact classes, weight thresholds, and endorsement codes differ. Your state's Department of Motor Vehicles website publishes a driver's handbook that lists every class and what it covers. Most DMV sites have a searchable PDF or online version you can read for free.
If you are unsure whether your current license covers a vehicle you want to drive, look up your state's DMV handbook and find the section on license classes. Match the vehicle's type and weight to the class descriptions. If you are still uncertain, call your state DMV — they can tell you in one call whether you need a different class or endorsement.
When you need to upgrade or change your license class
You may need to change your license class if you buy a vehicle outside your current class, take a job that requires commercial driving, or move to a state with a different system. If you move to a new state, you typically must obtain that state's license within 30 to 60 days. Some states allow you to transfer your old license; others require you to take the written and skills tests again.
If you want to add a motorcycle endorsement or upgrade to a CDL, you do not lose your current license — you take the additional test and the new class or endorsement is added. The process is the same whether you are 18 or 65.
Frequently Asked Questions
Can I drive a pickup truck with a Class D license?
Yes, as long as the truck's gross vehicle weight rating (GVWR) is below your state's threshold — usually between 10,000 and 26,000 pounds. Check your state's DMV handbook for the exact limit. If the truck is heavier, you need a CDL.
Do I need a separate license for a motorcycle or just an endorsement?
It depends on your state. Some states issue a separate Class M license; others allow you to add an M endorsement to your Class D. Check your state's DMV website to see which system applies where you live.
What happens if I drive a vehicle I'm not licensed for?
You can be cited for driving with an improper license class, which is a traffic violation. The fine and consequences vary by state, but it can result in points on your record and increased insurance rates.
Do I have to retake the test if I move to a new state?
Most states require you to obtain a new license within 30 to 60 days of moving. Some allow you to transfer your old license without retesting; others require you to pass the written and skills tests again. Contact your new state's DMV to find out their specific rules.
How long does it take to get a CDL?
The timeline varies, but most people spend two to four weeks from the medical exam to the skills test. You must schedule the medical exam first, then the written test, then the skills test — each step depends on passing the previous one.
