Maine Minimum Car Insurance Requirements (2026 Guide)
In Maine, the minimum car insurance you must carry is 50/100/25 liability coverage: $50,000 per person and $100,000 per accident for bodily injury, plus $25,000 for property damage. On top of that, Maine law also requires $2,000 in medical payments (MedPay) coverage and uninsured/underinsured motorist coverage at 50/100, making Maine one of the more protective minimum-coverage states in the country.
Maine's minimum car insurance requirements at a glance
Every owner or operator of a vehicle registered in Maine must maintain motor vehicle liability coverage before registering and driving that vehicle. Maine's minimums are higher than many states and include coverages that most states leave optional. To be legal on Maine roads, a personal auto policy must include:
- Bodily injury liability: $50,000 per person and $100,000 per accident
- Property damage liability: $25,000 per accident
- Medical payments (MedPay): at least $2,000 per person
- Uninsured/underinsured motorist (UM/UIM): $50,000 per person and $100,000 per accident
The shorthand 50/100/25 refers only to the liability portion. Maine also allows the liability requirement to be met with a single combined limit of $125,000. Because MedPay and UM/UIM are built into the mandatory minimum, a Maine policy at the legal floor already covers more situations than a bare-bones policy in most other states.
Maine is an at-fault (tort) state
Maine follows a traditional at-fault, or tort, system. When a crash happens, the driver who is legally responsible for causing it is liable for the resulting injuries and property damage, and that driver's liability insurance pays the people they harmed. An injured party can pursue the at-fault driver directly for medical bills, lost wages, vehicle repairs, and pain and suffering.
This is different from a no-fault system. Maine does not require personal injury protection (PIP); instead, it mandates a modest amount of medical payments coverage that pays medical costs for you and your passengers regardless of fault. Maine does require drivers to carry insurance. That contrasts with New Hampshire, the only state that does not have a compulsory auto-insurance mandate at all, though New Hampshire drivers still must be able to cover damages they cause. Neither Maine nor New Hampshire requires PIP.

Required coverages: liability, MedPay, and uninsured motorist
Liability coverage is the core of the requirement. Bodily injury liability pays for injuries you cause to others; property damage liability pays to repair or replace what you damage, such as another vehicle, a guardrail, or a fence. Liability does not pay for your own injuries or your own vehicle.
Medical payments (MedPay) of at least $2,000 per person covers reasonable medical expenses for you and your passengers after a crash, no matter who was at fault. It is a small but useful first layer of medical protection.
Uninsured/underinsured motorist (UM/UIM) coverage at 50/100 protects you when the at-fault driver has no insurance or not enough to cover your injuries. Given that some drivers still operate without coverage, this protection can be the difference between full recovery and being left with unpaid bills. In Maine, UM/UIM is not optional, which meaningfully raises the baseline level of protection for responsible drivers.
Optional coverages worth considering
Meeting the legal minimum keeps you street-legal, but it does not protect your own car or guarantee that a serious claim is fully covered. Common optional coverages include:
- Collision: pays to repair or replace your vehicle after a crash, regardless of fault.
- Comprehensive: covers non-collision losses such as theft, fire, vandalism, storm damage, and hitting an animal, which is a real risk on Maine's rural roads.
- Higher liability limits: raising limits well above 50/100/25 protects your savings if you cause a serious crash.
- Gap coverage: pays the difference between what you owe on a financed or leased vehicle and its actual cash value if it is totaled.
- Roadside assistance and rental reimbursement: convenience coverages that reduce out-of-pocket costs after a breakdown or claim.
If you finance or lease your vehicle, your lender will almost always require collision and comprehensive until the loan is paid off.
Penalties for driving without insurance in Maine
Because Maine ties insurance to registration, driving or registering a vehicle without the required coverage can carry real consequences. Drivers who operate uninsured may face fines, suspension of their driver's license and vehicle registration, and reinstatement fees to restore those privileges. A lapse discovered at a traffic stop or after a crash can quickly become expensive.
The financial exposure of being uninsured goes far beyond any fine. If you cause a crash while uninsured, you are personally responsible for the other party's medical bills and property damage out of your own pocket. A single serious injury claim can reach tens or hundreds of thousands of dollars, which can lead to wage garnishment or liens. Maintaining at least the required coverage is almost always far cheaper than the risk of going without it, especially given that Maine's average premiums are among the lowest in the nation.
Proof of financial responsibility and reinstatement
After certain serious violations, Maine drivers must file proof of financial responsibility before their driving and registration privileges are restored. Situations that commonly trigger this requirement include an OUI/DUI conviction or causing an accident while uninsured.
This proof is a certificate that a licensed insurance company files on your behalf, confirming that a policy meeting Maine's minimum limits is in force. Not every insurer offers this filing, and adding it can raise your premium, so it helps to ask before you buy. Once your privileges are reinstated, you generally must keep the proof active for about three years. If the underlying policy lapses or is canceled during that window, the state can suspend your license and registration again. Because the exact obligation depends on the specific violation, confirm your requirement directly with the state motor vehicle agency and your insurer rather than assuming a general rule applies to your case.
How much car insurance do you really need?
The 50/100/25 minimum is a legal floor, not a recommendation. Medical costs and vehicle values have risen sharply, and a single hospital stay after a multi-car crash can exhaust $50,000 or $100,000 quickly. If a claim exceeds your limits, you are personally liable for the difference.
Many advisors suggest carrying higher liability limits, such as 100/300/100, and matching UM/UIM limits to your liability so your own protection keeps pace with the coverage you extend to others. Drivers with meaningful assets, such as home equity or savings, often add an umbrella policy for an extra layer above their auto limits. If you own your vehicle outright and it is older, you might drop collision and comprehensive; if your car is newer, financed, or leased, keeping full coverage usually makes sense. The right amount balances your assets, your vehicle's value, and how much risk you are comfortable carrying yourself.
How to compare Maine car insurance quotes
Premiums for the exact same coverage can vary widely between insurers, so comparison shopping is the single most effective way to control cost. When you compare, hold the coverage constant so you are comparing like for like:
- Use identical liability, MedPay, and UM/UIM limits across every quote.
- Match your deductibles for collision and comprehensive.
- Ask about discounts for bundling home and auto, safe driving, low mileage, paperless billing, and good student status.
- Confirm whether a quoted policy includes any add-ons you did not request, which can distort the price.
- Check the insurer's complaint and claims-service record, not just the premium.
Get several quotes at your target coverage level and re-shop periodically, since rates change and loyalty does not always pay. Because Maine's average premiums are already low by national standards, a careful comparison can produce genuinely affordable protection well above the bare minimum.
Frequently asked questions
What is the minimum car insurance required in Maine?
Maine requires liability coverage of 50/100/25: $50,000 per person and $100,000 per accident for bodily injury, and $25,000 for property damage. In addition, Maine law requires at least $2,000 in medical payments (MedPay) coverage and uninsured/underinsured motorist coverage at $50,000 per person and $100,000 per accident.
Does Maine require uninsured motorist coverage?
Yes. Unlike many states where it is optional, Maine mandates uninsured/underinsured motorist (UM/UIM) coverage at a minimum of $50,000 per person and $100,000 per accident. It protects you if the driver who causes your crash has no insurance or not enough coverage to pay for your injuries.
Is Maine a no-fault state?
No. Maine is an at-fault (tort) state, meaning the driver responsible for a crash is liable for the resulting injuries and damage, and their liability insurance pays the other party. Maine does not require personal injury protection (PIP); it requires a small amount of medical payments coverage instead.
What happens if I drive without insurance in Maine?
Driving or registering a vehicle without the required coverage can lead to fines, suspension of your license and vehicle registration, and reinstatement fees. Beyond penalties, if you cause a crash while uninsured you are personally responsible for the other party's medical bills and property damage, which can be financially devastating.
Do I need to file proof of financial responsibility in Maine?
After serious violations such as an OUI/DUI conviction or causing a crash while uninsured, Maine can require you to file proof of financial responsibility before reinstatement. This is a certificate an insurer files confirming you carry at least the minimum coverage, and you generally must keep it active for about three years. Confirm your specific requirement with the state motor vehicle agency and your insurer.
Is 50/100/25 enough coverage in Maine?
It meets the law, but it may not be enough for a serious crash. Medical and repair costs can exceed those limits quickly, leaving you personally responsible for the difference. Many drivers choose higher limits, such as 100/300/100, and add collision, comprehensive, or an umbrella policy for stronger protection, especially since Maine's average premiums are among the lowest in the nation.
