The answer depends on your moped's engine size and your state
Whether you need a motorcycle license for a moped depends almost entirely on the engine size of the moped itself — not on what you call it. Most states draw a legal line at 50 cubic centimeters (cc). If your moped's engine is 50cc or smaller, you typically need only a regular driver's license and a moped endorsement or separate moped license. If it's larger than 50cc, you'll need a full motorcycle license in most states.
The reason for this split is that smaller mopeds are considered less powerful and therefore less risky than motorcycles. States treat them more like motorized bicycles than like motorcycles. But the exact rules vary by state, and some states have additional categories in between. Checking your specific state's motor vehicle department website is the only way to know for certain what you need.
Key Takeaways
- Mopeds with engines 50cc or smaller usually require only a regular driver's license plus a moped endorsement, not a full motorcycle license.
- Mopeds with engines larger than 50cc typically require a full motorcycle license in most states.
- Some states have a third category — sometimes called a motorized bicycle or limited-speed motorcycle — with its own separate license or endorsement.
- Your state's motor vehicle department website lists the exact engine size thresholds and what license type each requires.
- Even if you don't need a motorcycle license, you may still need to pass a written test or riding test for the moped endorsement.
How the 50cc threshold works in most states
The 50cc line exists because federal law treats mopeds and motorcycles differently for safety and emissions purposes. A moped at or below 50cc is legally defined as a moped in most states, while anything above that is a motorcycle. This isn't arbitrary — it's based on the power output and speed capability of the engine.
If your moped is 50cc or smaller, you can usually ride it with your regular driver's license, but you'll need to add a moped endorsement or obtain a separate moped license. Some states call this an "M" endorsement; others call it a "moped license" or "motorized bicycle license." The process to get this endorsement is usually simpler than getting a full motorcycle license — it may involve only a written test, or sometimes just a registration fee with no test at all.
If your moped is 51cc or larger, you'll need to take the full motorcycle licensing route in most states. This typically means passing both a written test and a riding skills test, or taking an approved motorcycle safety course that waives the riding test.
State-by-state variation in moped licensing
Not every state uses the exact same 50cc cutoff or the same license categories. Some states have created a middle tier for machines that are more powerful than a traditional moped but not quite a full motorcycle. These are sometimes called "limited-speed motorcycles" or "motorized bicycles," and they may have their own endorsement or license type.
For example, some states set the moped threshold at 50cc but then create a second category for 50cc to 150cc machines that requires a different endorsement than a full motorcycle license. Others may have different age requirements for moped riders versus motorcycle riders. A few states don't recognize mopeds as a separate category at all and require a motorcycle license for any motorized two-wheeler.
The only way to know what your state requires is to visit your state's Department of Motor Vehicles website or call their licensing division directly. They can tell you the exact engine size thresholds, what license or endorsement you need, and what tests or fees are involved.
What you'll need to bring when you get your moped endorsement
If you're getting a moped endorsement for a 50cc or smaller moped, you'll typically need your current driver's license, proof of residency (like a utility bill or lease), and proof of vehicle ownership or registration. Some states also require proof of insurance before they'll issue the endorsement, even though insurance requirements for small mopeds are often minimal or optional.
If you're upgrading to a full motorcycle license because your moped is over 50cc, the requirements are the same as for any motorcycle license in your state. You'll need your driver's license, proof of residency, and proof of ownership of the motorcycle or moped. You may also need to show proof of completing a motorcycle safety course if you're using that to waive the riding test.
Bring originals and copies of everything, because some offices will keep a copy on file. Call ahead to confirm exactly what your local office accepts as proof of residency and ownership — requirements can differ between counties.
Taking the written test for a moped endorsement
Most states that offer a moped endorsement require you to pass a written test covering basic moped operation, traffic laws, and safety. The test is usually shorter and less detailed than a full motorcycle license test. It covers things like how to brake on a moped, how to handle turns at low speed, and how to share the road with cars.
You can study using your state's motorcycle or moped handbook, which is free and available on the motor vehicle department website. Some states offer practice tests online as well. The written test typically takes 20 to 30 minutes and you need to score around 80 percent to pass.
A few states don't require any test for a moped endorsement — they only require registration and proof of ownership. Check your state's rules before you go to the office, so you know whether to study or not.
Whether you need a riding test for a moped
Most states do not require a riding skills test for a moped endorsement on a 50cc or smaller machine. They assume that if you already have a driver's license, you have enough vehicle control experience to handle a small moped safely. You'll pass the written test and pay the fee, and you're done.
However, if your moped is over 50cc and you need a full motorcycle license, you will need to pass a riding test in most states — unless you complete an approved motorcycle safety course, which typically waives the riding portion. The riding test is conducted by a motor vehicle examiner and usually takes 15 to 20 minutes. You ride a motorcycle or moped around a closed course and demonstrate basic skills like starting, stopping, turning, and swerving.
If you're nervous about the riding test, taking a motorcycle safety course is often worth it. These courses teach you proper technique, give you practice time on a real bike, and the certificate usually waives the state riding test. Many insurance companies also offer discounts for riders who complete an approved course.
Insurance and registration for mopeds versus motorcycles
Insurance and registration requirements also depend on engine size and your state. A 50cc or smaller moped may not require insurance in your state, or insurance may be optional. However, many states are moving toward requiring at least liability insurance for all motorized vehicles, including small mopeds. Check your state's rules before you ride.
Registration is almost always required, even for a 50cc moped. You'll register it at the same office where you get your moped endorsement, and you'll need proof of ownership (the title or bill of sale) and proof of residency. Registration fees for mopeds are usually lower than for motorcycles.
If your moped is over 50cc, insurance and registration requirements are the same as for any motorcycle in your state. You'll need liability insurance, and you'll register it as a motorcycle. Motorcycle insurance is typically more expensive than moped insurance because the machines are more powerful and statistically more likely to be in accidents.
Frequently Asked Questions
Can I ride a 50cc moped with just my regular driver's license?
No — you need to add a moped endorsement or get a separate moped license, even for a 50cc machine. Your regular driver's license alone does not cover moped riding. The endorsement process is usually quick and inexpensive, but it is a separate step from your driver's license.
What if I buy a moped and don't know the engine size?
Check the owner's manual or look at the vehicle's title or registration — both will list the engine displacement in cubic centimeters (cc). If you can't find either, the manufacturer's website or a local moped dealer can tell you the engine size based on the model and year.
Do I need a motorcycle license if I ride a moped in a different state?
Your moped endorsement from your home state is usually recognized in other states, but the rules for what you can ride may differ. If you're traveling with a 50cc moped, you should be fine in most states. If your moped is larger, check the destination state's rules before you go, because some states may not recognize your endorsement or may have different size categories.
Can I get a moped endorsement without taking a test?
It depends on your state. Some states require only a written test; others require only registration and proof of ownership with no test at all. A few states require both a written test and a riding test. Contact your state's motor vehicle department to find out what your state requires.
If I get a motorcycle license, can I ride any size moped?
Yes — a full motorcycle license covers all motorcycles and mopeds, regardless of engine size. However, a motorcycle license requires more testing and study than a moped endorsement, so if you only plan to ride a small moped, getting just the moped endorsement is simpler and cheaper.
