State Requirements
Maine operates as a traditional tort state where the at-fault driver is financially responsible for injuries and damage. All drivers must carry proof of insurance and file it with the Bureau of Motor Vehicles. Maine is one of few states requiring both medical payments coverage and uninsured/underinsured motorist protection at minimum liability limits, adding approximately $15–$25/month to the base premium compared to liability-only states.
Cost Overview
Maine's mandatory medical payments and uninsured motorist requirements push minimum coverage costs 15–20% higher than neighboring New Hampshire, which has no mandatory insurance. Portland and Bangor metro drivers pay 25–35% more than rural areas due to higher collision frequency and theft rates.
What Affects Your Rate
- Portland drivers pay $140–$190/month for minimum coverage compared to $85–$115/month in rural Aroostook County due to 40% higher accident frequency in the metro area.
- Drivers over 55 with clean records save 12–18% compared to under-25 drivers, with minimum coverage dropping to $75–$105/month for seniors in low-density areas.
- A single at-fault accident raises premiums by 30–45% for three years, increasing minimum coverage costs by approximately $25–$45/month.
- Comprehensive claims for animal strikes — Maine averages over 3,000 reported deer collisions annually — don't typically raise rates but require carrying optional comprehensive coverage at $15–$25/month.
- Vehicles over 10 years old see collision premium reductions of 50–60% compared to new cars, but the coverage still costs $30–$50/month even on a $3,000 vehicle, often exceeding its replacement value within 2–3 years.
- Credit-based insurance scores impact rates by 25–40% in Maine, with drivers in the lowest tier paying $115–$165/month for minimum coverage versus $75–$95/month for excellent-credit drivers with identical records.

Liability Insurance
Maine's 50/100/25 minimum is higher than most states, but a serious injury crash can generate medical bills exceeding $100,000. Increasing to 100/300/50 costs $15–$25/month and protects your savings and wages from lawsuit judgments.
Full Coverage
Combines liability, medical payments, uninsured motorist, collision, and comprehensive. Only financially rational if your vehicle is worth more than $6,000 or a lender requires it — otherwise annual premiums can exceed your car's replacement value.
Collision Coverage
Repairs your vehicle after an accident regardless of fault, minus your deductible. For a $3,500 car with $500 deductible, you pay $400–$650/year to protect a maximum $3,000 claim — break-even occurs in 5–8 years if you never file a claim.
Comprehensive Coverage
Covers theft, vandalism, weather damage, and animal strikes. Maine records over 3,000 deer collisions per year, concentrated in rural areas during fall mating season, but comprehensive costs $180–$280/year even with a $500 deductible.
Uninsured Motorist Coverage
Mandatory in Maine at 50/100/25 limits unless rejected in writing. Covers your injuries and damage when hit by an uninsured driver or in hit-and-run crashes where the at-fault party is never identified.
SR-22 Insurance
Not a coverage type but a state filing proving you carry minimum insurance after DUI, suspended license, or multiple violations. Maine requires SR-22 for 3 years, and the filing fee is $25–$50, though your underlying premium may increase 50–80% due to high-risk classification.
