Maine Auto Insurance: Average Cost & Requirements (2025)

Why Maine Rates Are Low

Maine's average full-coverage auto insurance rate of $1,080/year is 38% below the $1,750 national average. Rates are driven by population density, uninsured driver rates, local litigation costs, weather events, and state-mandated coverage requirements. Lower population density, fewer severe weather events, and competitive local insurance markets keep rates down.

How to Lower Your Rate in Maine

• Bundle home and auto with the same insurer — average saving: 15–20%
• Raise your deductible from $500 to $1,000 — saves $200–400/year on average
• Ask about low-mileage discounts if you drive under 7,500 miles/year
• Take a defensive driving course — qualifies for 5–15% discount with most carriers
• Pay annually instead of monthly — eliminates installment fees ($50–120/year)
• Compare at least 3 quotes — rates for the same driver can vary 40–60% across insurers
