A Class M license is for motorcycles and motorized bicycles
A Class M driver license is the license you need to legally ride a motorcycle on public roads. Some states also use it for motorized bicycles or mopeds, depending on the engine size and top speed. The exact rules about what vehicles fall under Class M vary by state — a 50cc moped might need a Class M in one state and not in another.
You cannot legally ride a motorcycle without one, even if you own the bike outright. Riding without the proper license can result in a fine, points on your driving record, or both. If you cause an accident while unlicensed, your insurance may not cover the damage.
Key Takeaways
- A Class M license is required to ride a motorcycle on public roads in all 50 states, though the exact vehicles covered vary by state.
- You must pass a written test on motorcycle safety and traffic laws, and a riding skills test on an actual motorcycle.
- Most states require you to complete a motorcycle safety course to waive the riding test, and some offer the course for free or low cost.
- The cost ranges from about $20 to $100 depending on your state and whether you take a safety course.
- You can add a Class M endorsement to an existing driver license rather than getting a separate license.
What vehicles require a Class M license
A Class M license covers motorcycles — two-wheeled vehicles with an engine of any size. It also typically covers three-wheeled motorcycles (trikes) and motorized bicycles or mopeds, though the engine size threshold for mopeds varies. In some states, a moped with an engine under 50cc does not require a Class M; in others, any motorized two-wheeler needs one.
Check your state's Department of Motor Vehicles website to see the exact definitions. The distinction matters because riding a moped without the proper license carries the same penalties as riding a motorcycle without one. If you are unsure whether your vehicle requires a Class M, the DMV can tell you based on the engine size and design.
How to get a Class M license or endorsement
You have two main paths: take a motorcycle safety course, or study on your own and pass the written and riding tests at the DMV.
The safety course route is faster and easier. You attend a classroom session (usually 4 to 8 hours) and a riding session (usually 4 to 8 hours, spread over one or two days). The course covers motorcycle handling, road positioning, hazard awareness, and state traffic laws. If you pass, you get a certificate that you bring to the DMV, and in most states this waives the riding test. You still take the written test, but many states waive that too. The course costs $100 to $300 depending on your state, though some states offer it free through community colleges or nonprofits.
The self-study route means you study the motorcycle manual on your own, take the written test at the DMV, and then take the riding test on a motorcycle you provide (or sometimes the DMV provides one). You must pass both to get the license. This route is cheaper upfront but requires you to already know how to ride or be willing to learn on your own before the test.
Most states let you add a Class M endorsement to your existing driver license rather than getting a separate license. You pay a smaller fee (usually $15 to $50) and follow the same test or course path. Your license will show the M endorsement, and you keep all your other driving privileges.
What the written test covers
The written test asks about motorcycle-specific safety and handling. You will see questions about braking distance, how to lean in a turn, what to do if your brakes fail, how to position yourself in a lane to be seen by other drivers, and how to handle road hazards like gravel or potholes. The test also covers state traffic laws as they explore to motorcycles — speed limits, helmet laws, and right-of-way rules.
Most states let you take the test on a computer at the DMV. You usually need to pass with a score of 80 percent or higher. If you fail, you can retake it after a waiting period (often a few days to a week). The motorcycle manual your state publishes covers everything on the test, and you can read it free from the DMV website.
What the riding test covers
The riding test takes place in a closed course or parking lot, not on public roads. An examiner watches you perform a series of maneuvers: starting the bike, riding in a straight line, making sharp turns, braking hard, and swerving to avoid an obstacle. The test usually lasts 10 to 15 minutes. You must wear a helmet and protective gear, and the bike must be street-legal and in working order.
The examiner is looking for smooth control, proper use of the clutch and brakes, awareness of your surroundings, and the ability to handle the bike at low and high speeds. If you take a safety course, you usually do not have to take this test — the course instructors sign off that you can ride safely. If you fail the riding test, you can retake it after a waiting period, usually a week or two.
Helmet laws and safety gear requirements
All 50 states require motorcycle riders to wear a helmet that meets Department of Transportation (DOT) standards. Some states require helmets only for riders under a certain age (often 18 or 21), but most require them for all riders. Violating the helmet law can result in a fine of $50 to $200 or more, depending on the state.
Beyond helmets, most states do not legally require protective gear like jackets, gloves, or boots, though they are strongly recommended. A safety course will teach you why protective gear matters and what to look for. If you are in an accident and were not wearing a helmet, your insurance may deny your claim or reduce your payout.
Renewing or upgrading your Class M license
A Class M license or endorsement renews on the same schedule as your regular driver license — usually every 4 to 8 years, depending on your state. You renew by mail, online, or in person at the DMV. Most states do not require you to retake the test when you renew; you just pay the renewal fee.
If you let your license expire, you will have to retake the written test and possibly the riding test to restore it, depending on how long it has been expired. Some states give you a grace period (often 30 days) to renew without penalty.
Frequently Asked Questions
Do I need a Class M license to ride a motorized bicycle or moped?
It depends on your state and the engine size. Most states require a Class M for any motorized two-wheeler with an engine over 50cc. Some states have a separate moped or motorized bicycle license for smaller engines. Check your state DMV website or call to confirm what your vehicle needs.
Can I take the motorcycle safety course online?
The classroom portion can sometimes be done online, but the riding portion must be in person. You need to practice on an actual motorcycle with an instructor watching. Some courses are hybrid, with online classroom and in-person riding.
What if I fail the riding test?
You can retake it after a waiting period, usually one to two weeks. You pay the test fee again. If you keep failing, consider taking a safety course — the instructors can identify what you are struggling with and help you improve before the test.
Do I need a Class M license if I only ride on private property?
No. A Class M license is only required for riding on public roads. If you ride only on your own land or a private track, you do not need one. However, once you ride on any public road, including a parking lot open to the public, you need the license.
Can I get a Class M license if I have had a DUI or other traffic violation?
Most states do not disqualify you from getting a Class M based on past violations. However, if your driver license is suspended or revoked, you cannot get a Class M until it is restored. Some states may require you to complete additional safety training if you have had serious violations.
