Most states require moped insurance, but the rules depend on engine size and where you live
Whether you need insurance on a moped comes down to your state's laws and your moped's engine size. Most states require insurance for any motorized two-wheeler, but some states exempt very small mopeds — usually those with engines under 50 cubic centimeters (cc). Even where insurance is not legally required, your lender or landlord may demand it, and riding without it when it is required carries real penalties: fines, license suspension, and liability for damages if you cause an accident.
The confusion happens because states use different terms. Some call them mopeds, some say motorized bicycles or motor scooters, and the engine size threshold changes from state to state. A 50cc moped might be uninsured in one state and require full coverage in another. The only way to know for certain is to check your specific state's motor vehicle code or call your state's Department of Motor Vehicles.
Key Takeaways
- Most states require insurance for mopeds over a certain engine size, commonly 50cc, though some states have no threshold at all.
- Even if your state does not legally require insurance, a lender, landlord, or employer may require you to carry it as a condition of the loan or lease.
- Riding without required insurance can result in fines, license suspension, and personal liability for any damages or injuries you cause.
- Your state's Department of Motor Vehicles can tell you the exact insurance requirement for your moped's engine size in minutes.
How states define mopeds and set insurance thresholds
States do not all use the same definition. Some states call anything under 50cc a motorized bicycle and do not require insurance. Others classify anything with an engine as a motor scooter and require insurance regardless of size. A few states have no engine-size threshold at all — if it has a motor, it needs insurance.
The 50cc threshold appears in many states because it is a common international standard, but it is not universal. Some states use 35cc, others use 49cc, and some do not use an engine-size rule at all. Your moped's registration paperwork will list its engine displacement. Take that number and your state name to your state's DMV website or call the office directly — they can tell you in one conversation whether insurance is required.
If you are buying a moped and the seller or dealer does not know the requirement, that is a red flag. A legitimate dealer should know their state's law and be able to tell you what you need before you hand over money.
What happens if you ride without required insurance
The penalties vary by state, but they are not small. Most states fine you between $100 and $500 for riding without insurance when it is required. Some states also suspend your driver's license for a set period — often 30 days to a year — which affects your ability to drive a car as well. A few states can impound your moped until you show proof of insurance.
The financial risk goes beyond the fine. If you cause an accident and do not have insurance, you are personally liable for all damages and medical bills. A single serious injury can result in a lawsuit that follows you for years. Insurance protects you from that exposure, which is why states require it in the first place.
When insurance is required even if your state does not mandate it
Even if your state does not legally require moped insurance, three situations can force you to carry it anyway. First, if you financed the moped through a loan, the lender almost always requires comprehensive and collision coverage as a condition of the loan. Second, if you rent an apartment or house, your landlord may require you to carry liability insurance before you can park a moped on the property. Third, some employers require employees who commute on mopeds to carry insurance.
Read any loan agreement, lease, or employment contract carefully before you buy. If insurance is required and you do not carry it, you are in breach of contract, which can result in the lender repossessing the moped or your landlord evicting you. It is easier to understand the requirement upfront than to discover it after you have already bought the moped.
What type of insurance you typically need
Moped insurance usually comes in two forms: liability only, or liability plus comprehensive and collision. Liability insurance covers damage or injuries you cause to someone else — their medical bills, their vehicle repair, their property. It is the minimum most states require. Comprehensive and collision cover damage to your own moped from accidents, theft, weather, or vandalism.
If you own the moped outright, you can choose liability only. If you financed it, the lender will require comprehensive and collision until the loan is paid off. Liability-only policies are cheaper, often $100 to $300 per year for a moped, while full coverage can run $300 to $600 or more depending on your age, location, and driving record. Get quotes from a few insurers — rates vary significantly, and some specialize in motorcycle and moped coverage.
How to find out your state's specific requirement
Start with your state's Department of Motor Vehicles website. Most states have a page about motorcycle or moped registration that lists insurance requirements. If the website is unclear, call the DMV directly — have your moped's engine size in cubic centimeters ready, and ask whether insurance is required for that size in your state.
If you are buying a moped and do not yet own one, ask the dealer or seller for the engine size before you commit. You can also search "[your state] moped insurance requirement" in a search engine and look for the official state DMV page in the results. Avoid relying on forums or social media — people often misremember or confuse their state's rules with another state's.
Registering a moped without insurance when it is not required
If your state does not require insurance for your moped's engine size, you can still register it without a policy. However, you will still need to register it with your state — registration and insurance are separate requirements. Registration typically costs $20 to $100 depending on your state and the moped's age, and you will need proof of ownership, a bill of sale, and a completed registration form.
Even if insurance is not legally required, consider carrying at least liability coverage. The cost is low, and the protection is real. One accident where you injure someone can cost you tens of thousands of dollars out of pocket if you are uninsured. Many people choose to carry insurance even when the law does not require it, straightforward because the risk is not worth the savings.
Frequently Asked Questions
Do I need insurance if my moped is under 50cc?
It depends on your state. Many states do not require insurance for mopeds under 50cc, but some require it regardless of engine size. Check your state's DMV website or call them directly with your moped's exact engine displacement to find out.
What if I ride without insurance and get pulled over?
If your state requires insurance and you do not have it, you can be fined $100 to $500 and may have your license suspended. The officer will likely issue a citation, and you may be required to show proof of insurance within a certain number of days to avoid additional penalties.
Can I get moped insurance if I do not own the moped yet?
Most insurers require you to own the moped or have a purchase agreement in place before they will issue a policy. Once you have decided on a specific moped, contact insurers for quotes — many can bind coverage within hours of purchase.
Is moped insurance cheaper than motorcycle insurance?
Yes, moped insurance is typically cheaper because mopeds are smaller, slower, and considered lower-risk. Liability-only moped policies often cost $100 to $300 per year, while motorcycle insurance can be $400 to $1,000 or more depending on the bike and rider age.
What if my state does not require insurance but my lender does?
You must carry the insurance your lender requires, even if your state does not mandate it. The lender's requirement is a condition of the loan agreement. If you do not carry it, the lender can repossess the moped or take legal action against you for breach of contract.
