- Maine's low rates make minimum coverage less of a compromise than in high-cost states — but full coverage is still worth considering
Maine is one of the best states in the country for auto insurance affordability. The state average is $1,468 per year for full coverage — nearly $1,000 below the national average of roughly $2,500. Maine has consistently ranked in the bottom five states for insurance costs for years, and the structural reasons for that are unlikely to change anytime soon.
The primary driver of Maine's low rates is simple: the state has one of the lowest population densities east of the Mississippi. With fewer than 1.4 million residents spread across a large geography, traffic volumes on most Maine roads are modest. Lower traffic means fewer accidents, fewer claims, and lower carrier losses — savings that flow back to policyholders in the form of lower premiums. Maine also has one of the lowest rates of uninsured drivers in the country, which keeps uninsured motorist coverage costs down for everyone.
What does add cost in Maine
Maine's main insurance cost drivers are weather-related. Harsh winters mean more collision claims from ice and snow — vehicles slide, cars hit guardrails, and fender-benders multiply during freeze-thaw cycles. The state also has significant deer-vehicle collision exposure, particularly in rural areas, making comprehensive coverage a practical necessity rather than an optional add-on. Portland, the state's largest city, has somewhat higher rates than the statewide average, but it remains affordable by any national comparison.
Even in a cheap market, switching carriers at renewal can save Maine drivers $300–$500 per year. The best carrier for your neighbor isn't necessarily the best for you — credit score, age, vehicle type, and annual mileage all factor into individual pricing in ways that vary significantly by carrier.
Maine average: $1,468/year full coverage. National average: ~$2,500. Maine drivers pay roughly 41% less than the typical American driver — one of the best rates in the nation.
If you've moved to Maine from a higher-cost state, your current carrier may not be repricing your policy to reflect your new low-risk environment. Shopping at your next renewal is the simplest way to capture the benefit of living in one of the cheapest insurance markets in the country.

The high mandatory coverage minimums are somewhat offset by the low claims frequency.
