Most states require a license or endorsement to ride a moped, but the rules depend on engine size and where you live
Whether you need a license for a moped comes down to two things: your state's definition of a moped, and the engine size of the machine you want to ride. In most states, anything with an engine larger than 50 cubic centimeters (cc) requires at least a regular driver's license. Smaller mopeds — typically 50cc or under — may only need a moped-specific endorsement or permit, or in a few states, no license at all. But "moped" means different things in different places, so you cannot assume your state treats it the way the one next to it does.
The reason this matters: riding without the right license can result in a ticket, a fine, and sometimes a misdemeanor charge. Your insurance may also refuse to cover an accident if you were not properly licensed. Before you buy or ride, check your state's motor vehicle department website or call their licensing division to confirm what your state requires for the specific machine you are considering.
Key Takeaways
- Most states require a regular driver's license or a separate moped endorsement to ride anything with an engine larger than 50cc.
- Mopeds with 50cc engines or smaller may only need a moped-specific permit or endorsement, which usually requires a written test but not a road test.
- A few states allow riders to operate 50cc mopeds with only a regular driver's license and no additional endorsement.
- Your state's motor vehicle department website lists the exact engine size threshold and what license type you need for each category.
- Riding without the correct license can result in a ticket, fine, or misdemeanor charge, and your insurance may not cover accidents.
How states define mopeds and set engine size thresholds
Each state draws the line between a moped and a motorcycle at a different engine size. Most commonly, the threshold is 50cc — anything at or below that size is treated as a moped, and anything above it is a motorcycle. However, some states use 49cc as the cutoff, and a few use different thresholds entirely. This matters because the license requirement jumps at that line: a 50cc moped may only need a permit, while a 51cc machine requires a full motorcycle endorsement.
Some states also consider other factors beyond engine size, such as top speed or whether the machine has pedals. A few states still recognize the old definition of a moped as a motorized bicycle with pedals, which can affect what license you need. Because these definitions vary, a moped that is legal to ride without a motorcycle endorsement in one state might require a full motorcycle license in another.
Your state's motor vehicle handbook — available free on your state's DMV website — lists the exact definition and the engine size threshold. If you are unsure whether a specific machine counts as a moped in your state, contact your state's motor vehicle department directly and describe the machine by its engine size in cubic centimeters.
License and endorsement options for mopeds under 50cc
If your state allows you to ride a moped under 50cc with only a moped endorsement or permit, you typically do not need to take a road test. Instead, you will study a short section of your state's driver's manual focused on moped operation and pass a written test at your local DMV office. The test usually covers basic safety, right-of-way rules, and moped-specific handling. Some states also require a vision test and a background check, but the process is faster and less involved than getting a full driver's license.
The moped endorsement or permit is usually valid for the same period as your driver's license — often four to eight years depending on your state. You will renew it at the same time you renew your license. The cost varies by state but is typically between $10 and $50, much less than a full motorcycle endorsement.
A few states do not require any endorsement at all for mopeds under 50cc if you already hold a valid driver's license. In those states, your regular license is sufficient. However, you should still read the moped section of your state's driver's manual to understand the rules specific to moped operation, even if no test is required.
When you need a full motorcycle endorsement
If your moped has an engine larger than your state's threshold — usually 50cc — you will need a full motorcycle endorsement on your driver's license. This is the same endorsement required for any motorcycle, and it requires both a written test and a riding skills test. The written test covers motorcycle-specific rules, hazard awareness, and emergency maneuvers. The riding test takes place on a closed course and evaluates your ability to control the machine, brake, turn, and handle obstacles.
Some states allow you to waive the riding test if you complete an approved motorcycle safety course, such as one offered by the Motorcycle Safety Foundation. These courses typically take one or two days and teach basic operation and safety. Completing the course often costs $100 to $300, but it can save you the time and stress of the DMV riding test and may lower your insurance premium.
A motorcycle endorsement is more expensive than a moped endorsement — usually $15 to $100 depending on your state — and the process takes longer because of the riding test. However, once you have it, you can legally ride any motorcycle in your state, not just mopeds.
What happens if you ride without the correct license
Riding a moped or motorcycle without the required license or endorsement is a traffic violation in every state. The penalty varies, but typically includes a fine ranging from $100 to $500, and in some states a misdemeanor charge that can result in jail time. A conviction also goes on your driving record and can affect your insurance rates for years.
Beyond legal consequences, riding without the correct license creates a serious insurance problem. If you are in an accident and your insurance company discovers you were not properly licensed, they may refuse to pay for damages or medical bills. This means you could be personally liable for all costs, including damage to the other person's vehicle or injuries they sustained.
Additionally, if you are stopped by police and cannot show proof of the correct license or endorsement, your moped may be impounded, and you may face additional fines for operating an unregistered or unlicensed vehicle.
How to check your state's specific requirements
The fastest way to find out what your state requires is to visit your state's motor vehicle department website and search for "moped" or "motorized bicycle." Most states have a dedicated page that lists the engine size threshold, the type of license needed, and the steps to get it. You can also call your state's motor vehicle department directly — the phone number is on the website — and ask a representative what license you need for a specific machine.
If you are buying a moped from a dealer, ask them what license your state requires for that model. They deal with this question regularly and can usually tell you when ready. If you are buying from a private seller, look up the machine's engine size in the owner's manual or on the manufacturer's website, then check your state's requirements based on that number.
Some states also have a moped registration process separate from licensing. Even if your state does not require a license for a 50cc moped, you may still need to register it with the DMV and carry proof of registration when you ride. Check your state's website to confirm whether registration is required in addition to licensing.
Frequently Asked Questions
Can I ride a moped with just a regular driver's license?
It depends on your state and the moped's engine size. In most states, a regular driver's license is enough for mopeds 50cc or smaller. For anything larger, you need a motorcycle endorsement. Check your state's motor vehicle website to confirm what your license covers.
Do I need to take a road test to get a moped endorsement?
Most states do not require a road test for a moped endorsement — only a written test. However, if your moped is large enough to require a full motorcycle endorsement, you will need to pass both a written test and a riding skills test, unless you complete an approved motorcycle safety course.
What if I already have a motorcycle license — can I ride any moped?
Yes. A motorcycle endorsement covers all motorcycles and mopeds, regardless of engine size. If you already have a motorcycle license, you can legally ride any moped in your state without any additional steps.
How much does a moped endorsement cost?
Moped endorsement fees vary by state but typically range from $10 to $50. A full motorcycle endorsement costs more, usually $15 to $100. Check your state's motor vehicle department website for the exact fee in your state.
What do I need to bring to the DMV to get a moped endorsement?
You will need a valid ID, proof of residency, and your Social Security number. Some states also require a vision test. Bring your current driver's license if you already have one. Check your state's motor vehicle website for a complete list of required documents before you go.
