Car Insurance in Maine: Broad Minimums, the Nation's Lowest Bill

$1,262 a Year. Lowest in the Country.

That's the average Maine driver's bill for state-minimum coverage, and per the 2026 NAIC report, no other state in the country averages less for auto insurance. Full coverage runs $1,704 a year — still near the bottom nationally, even though Maine's minimum requirements are broader than most states demand.

That combination — broad mandates, low prices — doesn't match how insurance pricing usually works, and it's worth understanding why before you assume your quote will land near the state average.

What 50/100/25 Actually Requires

Maine's floor is 50/100/25 liability: $50,000 per person in bodily injury coverage, $100,000 per accident, $25,000 for property damage. That alone is higher than what states like Connecticut or Texas require. Then Maine adds two more mandates most states leave optional — at least $2,000 per person in medical payments coverage, and uninsured/underinsured motorist coverage matched to the full 50/100 liability limits.

Put together, a Maine minimum policy already covers ground that drivers in plenty of other states have to buy as add-ons. It's closer to a mid-tier policy elsewhere than a bare-bones one.

Why the Price Doesn't Match the Coverage

Insurers price a policy against the risk of paying out, not just the size of the mandate. Maine's uninsured-driver rate sits at roughly 5.7%, the lowest of any state and well under half the national average near 14%. Fewer uninsured drivers means fewer unpaid UM/UIM claims eating into that broader required coverage.

Add lower population density outside cities like Portland and Bangor, less of the bumper-to-bumper congestion that drives claim frequency in bigger metros, and comparatively modest catastrophic weather losses next to hurricane-exposed Gulf and Atlantic states, and the math starts to make sense. Broad coverage, but a smaller pool of expensive claims to spread it across.

When the Maine Minimum Isn't Enough

The $25,000 property damage limit is the weak point. A single newer vehicle can exceed that on its own, and Maine's minimum doesn't raise that number even though it strengthens injury and uninsured-motorist protection. If you're driving anything late-model, or driving one, raising liability past the floor is the one place worth spending above Maine's already-low average.

• Raise property damage liability: $25,000 doesn't stretch far against a modern vehicle repair bill.
• Keep UM/UIM at full limits: it's already required at 50/100 — don't let an agent talk you down from it.
• Confirm your med-pay limit: $2,000 is the floor; bumping it costs little and pays first, regardless of fault.
• Re-shop at renewal anyway: a low state average doesn't mean every carrier prices your ZIP the same way.

Broad mandates and the lowest average bill in the country shouldn't coexist. In Maine, they do — and that's less a fluke than a state with fewer uninsured drivers and less claim pressure finally showing up in the price.
