Maine Car Insurance Requirements: Complete Guide

Maine car insurance requirements are among the most comprehensive in the nation, with higher minimum liability limits than most states and three mandatory coverage types. As an at-fault state requiring liability, medical payments, and uninsured/underinsured motorist coverage, Maine gives drivers strong baseline protection, but also more rules to understand. Knowing how these requirements work matters for every Maine driver.

This guide explains Maine’s car insurance requirements, including the minimum liability limits, the mandatory medical payments and uninsured motorist coverage, how the at-fault system works, optional coverages, and the penalties for driving uninsured. Understanding these rules helps you stay legal and protected on Maine roads.

Maine Is an At-Fault State

Maine operates under an at-fault (tort) system, meaning the driver who causes an accident is financially responsible for the resulting damages and injuries. The at-fault driver’s liability insurance pays for the other party’s medical bills, lost wages, pain and suffering, and property damage, up to the policy limits.

What sets Maine apart is that it requires more than just liability coverage, and its minimum liability limits are notably higher than most states. Drivers must carry three types of coverage: liability, medical payments (MedPay), and uninsured/underinsured motorist coverage. You must provide proof of insurance before registering your vehicle. Understanding all three requirements is essential to staying compliant in Maine.

Minimum Liability Requirements

Maine law requires every driver to carry minimum liability coverage of 50/100/25. The table below breaks down what those numbers mean.

Maine’s 50/100 bodily injury limits are double the 25/50 many states require, and a combined single limit of $125,000 also satisfies the requirement. Use our car insurance calculator to estimate appropriate coverage levels.

Medical Payments Coverage (MedPay)

Maine requires medical payments coverage (MedPay) of at least $2,000 per person. This coverage pays for medical and funeral expenses for you and your passengers after an accident, regardless of who was at fault, providing prompt first-party coverage without waiting for a fault determination.

The $2,000 minimum is modest, easily exhausted by even a minor injury requiring an emergency room visit. Fortunately, higher MedPay limits are relatively inexpensive, and many drivers carry $5,000 to $10,000 for more meaningful protection. Because MedPay pays regardless of fault and covers everyone in your vehicle, it’s a valuable supplement to your health insurance, especially useful for deductibles and copays after a crash. Given how low the minimum is, increasing it is worth considering.

Uninsured and Underinsured Motorist Coverage

Maine requires uninsured and underinsured motorist (UM/UIM) coverage at a minimum of $50,000 per person and $100,000 per accident (50/100), matching the liability minimum. If you choose higher liability limits, your UM/UIM coverage generally must match them unless you reject the higher amount in writing.

This coverage protects you and your passengers if a driver who causes an accident has no insurance, including in hit-and-runs, or has insurance but not enough to cover your injuries. UM/UIM acts as the insurance the at-fault driver should have carried. One important detail: Maine’s UM/UIM coverage applies to bodily injury only, it won’t pay for damage to your vehicle, which requires collision coverage. Maine’s relatively high required UM/UIM limits give drivers strong protection against uninsured and underinsured drivers.

Optional Coverages Worth Considering

Beyond the three required coverages, optional protections round out your policy. Collision coverage pays to repair or replace your own vehicle after a crash regardless of fault, and it’s the only way to cover your vehicle when an uninsured driver damages it, since UM/UIM covers bodily injury only. Comprehensive coverage protects against non-collision losses like theft, vandalism, fire, weather, and animal strikes (including deer and moose collisions, a real risk in Maine).

If you finance or lease your vehicle, your lender will require both collision and comprehensive. Other useful options include higher MedPay and liability limits, rental reimbursement, and roadside assistance. While Maine’s 50/100/25 minimums are higher than most states, they can still be exhausted by a serious accident, so raising your liability limits toward benchmarks like 100/300/100 remains a worthwhile upgrade for stronger asset protection.

Penalties for Driving Uninsured

Driving without insurance in Maine carries real consequences. Failing to maintain the required coverage can result in fines up to $500, suspension of your driver’s license, and suspension of your vehicle registration. You must carry proof of insurance and provide it when registering your vehicle and when requested by law enforcement.

Reinstating your license and registration after a lapse typically requires proof of insurance and payment of reinstatement fees, and you may face a requirement to file an SR-22 form proving financial responsibility. Beyond the legal penalties, driving uninsured leaves you personally liable for any accident you cause, with damages that could far exceed years of premiums, and without the MedPay cushion for your own injuries. Maintaining continuous coverage is essential.

Frequently Asked Questions

What are Maine’s minimum car insurance requirements?

Maine requires three coverages: liability of 50/100/25 ($50,000 bodily injury per person, $100,000 per accident, $25,000 property damage), medical payments (MedPay) of at least $2,000 per person, and uninsured/underinsured motorist coverage of at least 50/100 for bodily injury.

Is Maine an at-fault state?

Yes. Maine uses an at-fault (tort) system, so the driver who causes an accident is financially responsible for the resulting damages. The accident victim can file a claim with the at-fault driver’s insurer or pursue a personal injury lawsuit against the at-fault driver.

Does Maine require medical payments coverage?

Yes. Maine requires medical payments (MedPay) coverage of at least $2,000 per person, which pays medical and funeral expenses for you and your passengers regardless of fault. The minimum is modest, so increasing it to $5,000 to $10,000 for better protection is relatively inexpensive.

Does Maine require uninsured motorist coverage?

Yes. Maine requires uninsured/underinsured motorist coverage at a minimum of 50/100 for bodily injury, matching the liability minimum. If you carry higher liability limits, your UM/UIM generally must match unless you reject the higher amount in writing. It covers bodily injury only, not your vehicle.

Why are Maine’s minimum limits higher than other states?

Maine sets its minimum liability at 50/100/25, double the 25/50 bodily injury limits many states require. These higher minimums provide stronger baseline protection for accident victims and the at-fault driver, though they can still be exhausted by a serious accident.

Is the Maine minimum coverage enough?

Maine’s minimums are higher than most states, but a serious accident can still exceed them, leaving you personally responsible for the excess. Raising your liability limits toward 100/300/100 and increasing your low $2,000 MedPay are affordable ways to strengthen your protection.

What happens if I drive without insurance in Maine?

Penalties can include fines up to $500, license suspension, and registration suspension, plus reinstatement fees and a possible SR-22 requirement. You must show proof of insurance to register your vehicle. Driving uninsured also leaves you personally liable for any accident you cause.

What optional coverages should Maine drivers consider?

Consider collision and comprehensive (required if you finance or lease, with comprehensive valuable for deer and moose collisions), higher MedPay limits, and higher liability limits. Since UM/UIM covers bodily injury only, collision coverage is important to protect your own vehicle.

The Bottom Line

Maine requires three types of car insurance with higher minimums than most states: liability of 50/100/25, medical payments of at least $2,000, and uninsured/underinsured motorist coverage of 50/100. Under the at-fault system, the driver who causes an accident is responsible for the resulting damages, which is why liability protects others you harm but nothing of your own.

The required MedPay provides quick first-party medical coverage regardless of fault, while the relatively high mandatory UM/UIM limits protect you against uninsured and underinsured drivers, protection many states leave optional or set lower. Remember that UM/UIM covers bodily injury only, so collision coverage matters for your own vehicle, especially given Maine’s deer and moose collision risk.

Driving uninsured risks fines up to $500, license and registration suspension, and a possible SR-22 requirement, plus personal liability for any accident. Even though Maine’s minimums are higher than most states, a serious accident can exceed them, so carrying higher liability limits toward benchmarks like 100/300/100, increasing your low MedPay, and adding collision and comprehensive coverage protects you far better. Understanding these layered requirements helps you drive legally and confidently on Maine roads.
