Why Maine is the cheapest state in the country
Maine's structural cost advantages are unusual. The state has the lowest uninsured-driver rate in the US (4.9% vs. ~13% national average), which means UM/UIM claim costs are minimal. Litigation expenses are low; jury awards run well below national averages. Theft and vandalism rates are among the lowest in any state. Population density outside Portland and Lewiston is very low, reducing accident frequency.
Maine also has unusual policy structure mandates that, paradoxically, keep average premiums low: every Maine auto policy must include $2,000 in MedPay coverage and uninsured/underinsured motorist coverage at the same limits as liability. This sounds expensive, but it lets the entire market price more efficiently because UM/UIM penetration is universal.
Even the high minimum liability requirement (50/100/25) doesn't push Maine premiums up significantly — the underlying loss costs are simply that low.
Cheapest carriers by Maine region
Maine has a healthy mix of regional New England carriers and national insurers. Based on rate comparisons we run for ME residents:
- Portland / Cumberland County: GEICO and Progressive are most often cheapest for clean records; Concord Group competes hard. State Farm runs 15–22% higher for the same profile.
- Lewiston / Auburn: Patriot Insurance (a Maine-domiciled regional) often beats nationals by 10–18%. Always quote.
- Bangor / Penobscot County: Concord Group and Patriot Insurance trade the top spot; GEICO competes well.
- Coastal York County (Kennebunk, Wells, Kittery): Progressive and GEICO dominate; rates run slightly higher than inland due to commuter mileage to MA.
- Aroostook County and rural northern ME: Patriot Insurance and MMG Insurance (another regional mutual) are typically cheapest; national carriers don't price these markets aggressively.
Maine's 50/100/25 + mandatory UM/UIM + $2,000 MedPay
Maine requires 50/100/25 minimum liability — $50,000 bodily injury per person, $100,000 per accident, $25,000 property damage — plus mandatory uninsured/underinsured motorist coverage at matching 50/100 limits, plus a $2,000 MedPay coverage minimum. Every Maine auto policy includes all of these by law.
These minimums are surprisingly adequate for most claim scenarios — the 50/100 floor is double what most states require. But upgrading to 100/300/100 with matching UM/UIM is still smart for anyone with assets and typically costs only $180–$320/year extra in Maine because base loss costs are so low.
Maine does not require PIP (it's a tort state). The mandatory $2,000 MedPay handles small medical bills regardless of fault. Optional MedPay upgrades to $5,000 or $10,000 cost $30–$80/year and are worth considering.
Discounts Maine drivers consistently miss
Maine's low base rates make percentage-based discounts especially valuable. Pull your declarations page and confirm:
- Pay-in-full: 4–10% off across most ME carriers.
- Paperless billing + autopay: another 2–5%.
- Continuous insurance credit: typically applies after 3+ years lapse-free; 10–15% off.
- Defensive driving course (ME-approved AAA or NSC): up to 10% off for 3 years.
- Telematics (Progressive Snapshot, State Farm Drive Safe & Save): 5–25% off after 90-day monitoring. Strong wins for low-mileage drivers.
- Homeowner discount even without bundling: 3–8% off — many ME drivers don't realize this applies without full bundle.
- Low annual mileage (under 7,500 mi/year): 5–12% off — easy to claim for retirees and remote workers.
- Vehicle anti-theft and safety features: most newer vehicles qualify; check the line items.
When to re-shop your Maine auto policy
Even in the cheapest state in the country, policy tenure matters. Carriers reward new business and drift renewal rates upward 3–7% per year. Maine drivers who've been with the same carrier 5+ years are typically $150–$400/year above market — a smaller absolute dollar amount than other states, but a meaningful percentage of a $1,000 baseline.
Re-shop triggers in Maine: any move (even within the same county), turning 25 or 65, paying off a financed vehicle, adding or removing a driver, a clean 36-month period after a previous ticket or accident, or any renewal increase over 6% with no claim activity.
There's no penalty for mid-term switches in Maine. Your old carrier owes you a prorated refund of unearned premium. With base premiums this low, even a 15% savings translates to $150/year — a couple of phone quotes is well worth the effort.
