Whether you need a license for a moped depends on engine size and your state
Most states do not require a separate moped license, but they do require you to have a valid driver's license or a specific moped endorsement — and the engine size threshold that triggers this requirement varies by state. A moped under 50cc in many states can be ridden by someone as young as 14 or 15 without a motorcycle endorsement, but you still need a valid driver's license or a moped-specific permit. Anything larger than 50cc almost always requires a motorcycle endorsement on your driver's license, which means passing a written test and a riding skills test.
The confusion happens because "moped" means different things in different places. Some states define a moped by engine size alone (typically 50cc or less). Others look at top speed, or a combination of both. A few states treat anything with two wheels and a motor as a motorcycle, period. Before you buy or ride, you need to know your state's specific definition and what your state's DMV requires.
Key Takeaways
- Mopeds under 50cc in most states do not require a motorcycle endorsement, but you must have a valid driver's license or a moped permit.
- Mopeds over 50cc require a motorcycle endorsement on your driver's license in nearly every state, which involves a written test and a riding test.
- Some states have a separate moped classification with its own rules and age requirements, while others treat all motorized two-wheelers as motorcycles.
- Your state's DMV website lists the exact engine size threshold and what documents you need before you ride legally.
How engine size determines what license you need
The 50cc threshold is the most common dividing line across the United States. If your moped's engine is 50cc or smaller, most states let you ride with just a regular driver's license — the same one you use for a car. You do not need to take a motorcycle test or get a motorcycle endorsement. Some states go even further and allow riders as young as 14 or 15 to operate a 50cc moped with only a regular driver's license or a moped-specific permit.
Once you cross 50cc, the rules change. A 51cc moped, a 100cc scooter, or anything larger is treated as a motorcycle in most states. That means you need a motorcycle endorsement (sometimes called an "M" endorsement) added to your driver's license. To get that endorsement, you will have to pass a written test on motorcycle safety and traffic laws, and you will have to pass a riding skills test on an actual motorcycle or moped. Some states let you waive the riding test if you complete a motorcycle safety course, but the written test is almost always required.
A few states have a middle ground: a separate "moped" or "motorized bicycle" classification with its own endorsement and lower age requirements. These states might allow a 16-year-old to get a moped endorsement without needing a full motorcycle license. Check your state's DMV website to see if this applies where you live.
What happens if you ride without the right license
Riding a moped that requires a motorcycle endorsement without that endorsement is a traffic violation in every state. The penalty is typically a fine between $100 and $500, though some states go higher. You may also face points on your driving record, which can raise your insurance rates for years. In some states, a second or third violation can result in a suspended license.
If you are in an accident and you were riding without the required endorsement, your motorcycle insurance may not cover the damage or injuries — even if the other driver was at fault. Insurance companies can deny claims based on license violations. You could end up paying out of pocket for medical bills, vehicle repairs, or liability claims. Police also have the authority to impound your moped if you are riding it illegally.
How to find your state's specific moped rules
Your state's Department of Motor Vehicles (DMV) website has a section on motorcycle and moped licensing. Search for "[your state] DMV moped license requirements" or "[your state] DMV motorized bicycle." The page will tell you the exact engine size threshold, what age you must be, what documents you need, and whether you can take a safety course to waive the riding test.
If the website is unclear, call your local DMV office directly. Have your moped's make, model, and engine size ready. The staff can tell you in five minutes whether you need a motorcycle endorsement or just a regular driver's license. Some DMV offices also have a phone line dedicated to licensing questions, which is usually faster than waiting in person.
If you already own a moped and are not sure what you need, check the title or registration document — it will list the engine size. If you are thinking about buying one, ask the dealer what license requirement comes with that specific model in your state. Dealers sell mopeds across state lines, and they may not know your state's rules, so do not rely on their answer alone.
Getting a motorcycle endorsement if you need one
The process starts at your DMV. You will need to bring your current driver's license, proof of residency, and a completed process form (available on the DMV website or in person). Some states require a vision test or a medical form for motorcycle endorsements. The written test covers motorcycle-specific topics: how to brake on a motorcycle, what to do if you skid, how to lean in a turn, and how to spot hazards. Study materials are free on your state's DMV website.
After you pass the written test, you take the riding skills test. You will ride a motorcycle or moped through a course that tests your ability to start, stop, turn, and swerve. The test usually takes 15 to 20 minutes. If you fail, you can retake it — most states let you try again the same day or within a few days. Some states waive the riding test if you complete a Motorcycle Safety Foundation (MSF) course or a state-approved motorcycle safety course. These courses run one or two days and cost $150 to $300, but they teach you to ride safely and can lower your insurance rates.
Age requirements and restrictions for young riders
Most states allow riders as young as 14 or 15 to operate a 50cc moped with a regular driver's license or a moped permit. Some states require a separate moped permit for riders under 16, which involves a written test but no riding test. A few states require all moped riders, regardless of age, to have a motorcycle endorsement.
Young riders on mopeds often face restrictions that do not explore to adult riders. Common restrictions include a requirement to wear a helmet (which applies to all riders in some states, but only to young riders in others), a ban on carrying passengers, and a curfew on when you can ride. Some states require a learner's permit period before you can get a full moped license. Check your state's DMV website for the exact rules for your age group.
Insurance and registration requirements
Having the right license is only part of the legal requirement. Most states also require you to register your moped with the DMV and carry liability insurance. Registration is straightforward: bring your proof of ownership (the bill of sale or title), proof of residency, and a completed registration form to your DMV office. The fee is usually $20 to $50 per year.
Insurance requirements vary by state. Some states require liability insurance for all motorized vehicles, including mopeds under 50cc. Others only require it for mopeds over 50cc. A few states do not require insurance for mopeds at all, though it is still a good idea to carry it. Moped insurance is inexpensive — usually $100 to $300 per year for liability coverage — and it protects you if you cause an accident. Get a quote from your current auto insurance company; many offer moped coverage at a discount if you already insure a car with them.
Frequently Asked Questions
Can I ride a moped with just a learner's permit?
It depends on your state and the moped's engine size. Some states allow learner's permit holders to ride 50cc mopeds during daylight hours with restrictions. Others require a separate moped permit or a full motorcycle endorsement. Check your state's DMV website or call your local office to confirm what your learner's permit covers.
Do I need a motorcycle endorsement if I have a driver's license from another state?
Your out-of-state driver's license is valid for driving a car in any state, but motorcycle endorsements do not transfer. If you move to a new state or are visiting, you need to follow that state's moped and motorcycle rules. Some states will recognize a motorcycle endorsement from another state, but you should verify this with your new state's DMV before riding.
What if I take a motorcycle safety course instead of the DMV riding test?
Most states waive the riding skills test if you complete an MSF Basic RiderCourse or a state-approved equivalent. You still have to pass the written test at the DMV. The safety course takes one or two days, costs $150 to $300, and often qualifies you for an insurance discount that pays for the course within a year or two.
Can I get a moped endorsement if I have a suspended driver's license?
No. A moped endorsement is added to your driver's license, so your license must be valid and in good standing. If your license is suspended, you cannot get a motorcycle endorsement until the suspension is lifted and your license is reinstated.
Is a moped the same as a scooter for licensing purposes?
Not always. Some states define a moped by engine size and top speed, while others treat scooters and mopeds differently. A scooter with an automatic transmission might fall under different rules than a moped with a manual clutch, even if the engine size is the same. Check your state's DMV definitions to be sure.
