Car Insurance in Maine: What You Need to Know

Maine drivers pay an estimated $97 per month ($1,161 per year) for auto insurance on average, about 36% below the national average of $150 per month ($1,803 per year) [1] [2]. Maine consistently ranks among the least expensive states for auto insurance in the country, a distinction driven by its low population density, sparse urban traffic, and relatively low rates of vehicle theft. What makes Maine stand out further is that it achieves these low rates while imposing some of the highest mandatory minimum coverage limits in the United States, giving drivers more baseline protection than most states require.

Coverage Requirements

Maine requires all registered vehicles to carry three types of coverage meeting these minimums [3]:

Liability coverage:

• $50,000 bodily injury liability per person
• $100,000 bodily injury liability per accident
• $25,000 property damage liability

Medical payments coverage:

• $2,000 per person for medical expenses

Uninsured/underinsured motorist (UM/UIM) coverage:

• $50,000 per person / $100,000 per accident

Maine's 50/100/25 liability minimums are notably higher than the national baseline. Many states still use 25/50/25 or lower limits from decades-old statutes, meaning Maine drivers start with more financial protection by default. The mandatory UM/UIM coverage also sets Maine apart. Most states only require liability coverage, leaving drivers to opt into uninsured motorist protection at their own discretion. In Maine, that protection is built into the baseline policy requirement, with your UM limit automatically matching your liability limit unless you reject the higher amount in writing [3].

Driving uninsured in Maine is a traffic infraction carrying a fine of $100 to $500, plus suspension of your license and vehicle registration until you provide proof of financial responsibility [4].

What Insurance Costs in Maine

At $97 per month, Maine is one of the most affordable states in the country for auto insurance. Several factors specific to the state explain why premiums stay this low despite the higher coverage minimums:

• Very low population density. Maine is the least densely populated state east of the Mississippi. Fewer vehicles on the road means fewer collisions per driver, which directly reduces claim frequency for liability and collision coverage.
• Low vehicle theft rates. Maine consistently posts some of the lowest auto theft rates nationally. Lower theft exposure holds down comprehensive coverage costs, which feed into overall premium calculations.
• Minimal urban congestion. Portland, Maine's largest city, has a small metro footprint compared to cities in neighboring Massachusetts or New York. Urban stop-and-go driving generates far more fender-bender claims than rural or small-city driving patterns.
• Winter weather exposure. Maine's harsh winters create genuine risk: black ice, multi-car chain accidents, and freeze-thaw road damage. Collision and comprehensive claims spike in winter months, which prevents Maine premiums from dropping even further than they already have.
• High minimums do not raise premiums significantly here. Maine's generous minimums come at relatively low additional cost because the underlying claim environment is so benign. Insurers price risk, not coverage limits in isolation, so a 50/100 limit in a low-claim state can still price out cheaper than a 25/50 limit in a high-congestion state.

How to Save on Coverage

• Use the Maine Bureau of Insurance policy comparison resource. The Maine Bureau of Insurance publishes policy forms from the state's 10 largest private passenger auto groups, allowing consumers to compare policy terms and conditions side by side. This is a useful starting point before contacting carriers for quotes [5].
• Understand available discounts before renewing. Maine insurers offer a range of discounts tied to driver behavior, vehicle safety features, bundling home and auto policies, and maintaining continuous coverage. The Maine Bureau of Insurance maintains a guide to common auto insurance discounts worth reviewing at each renewal [3].
• Compare quotes across multiple carriers at every renewal. Even in a low-cost state, pricing varies meaningfully between carriers for the same driver profile. Getting at least three quotes at renewal is the most reliable way to verify you are on a competitive rate rather than simply renewing a policy that may have drifted above market.
• Review collision and comprehensive on older vehicles. Maine's low theft rate and rural environment reduce the risk events that trigger comprehensive claims. On an older vehicle with a low market value, the annual cost of comprehensive and collision coverage may approach or exceed what you would collect after a total loss. Dropping those coverages on vehicles worth less than $4,000 to $5,000 is worth calculating.
• Maintain a clean driving record. A single at-fault accident typically adds 40% or more to your premium at renewal, and the surcharge typically stays on your record for three to five years. Maine's low base rates make maintaining them with a clean record especially worthwhile, since the gap between clean and surcharged rates is measured in years of savings.

Frequently Asked Questions

Is Maine a no-fault state?

No. Maine is an at-fault (tort) state. The driver responsible for causing a crash is financially liable for the other party's injuries and property damage through their liability insurance. Maine does require medical payments coverage of at least $2,000 per person, which covers your own medical expenses regardless of fault. However, this is not the same as the personal injury protection (PIP) system used in true no-fault states, which replaces the right to sue for most injury claims. In Maine, injured parties retain the right to pursue the at-fault driver for full compensation [3].

Why does Maine require uninsured motorist coverage?

Maine mandates uninsured and underinsured motorist coverage to protect drivers from financial loss when the at-fault party in a crash either has no insurance or carries insufficient limits to cover the damage they caused. Maine law requires your UM/UIM limit to match your liability limit unless you reject the higher amount in writing, meaning most Maine drivers automatically carry at least $50,000/$100,000 in UM/UIM protection. This is one of the stronger baseline consumer protections built into Maine's insurance code [3].

Is Maine actually one of the cheapest states for car insurance?

Yes. At roughly $97 per month, Maine consistently ranks among the five least expensive states for auto insurance nationally, well below the $150 per month national average [1]. The combination of low population density, minimal urban congestion, and low theft rates keeps claim frequency and severity down across the state. That said, individual rates vary significantly based on driving record, vehicle type, age, and credit history in states where credit scoring is permitted. Shopping across multiple carriers remains important even in a low-cost state.
