Maine requires 50/100/25 liability plus $2,000 med-pay and uninsured-motorist coverage on every motorcycle policy — the heaviest minimum package in the country, at a below-average price.

Maine requires more insurance on a motorcycle than any other state: liability of 50/100/25 — $50,000 per injured person, $100,000 per accident, $25,000 in property damage — plus $2,000 of medical-payments coverage [29-A M.R.S. § 1605, 2026], with uninsured-motorist coverage written into every policy by the state’s insurance code [24-A M.R.S. § 2902, 2026]. The odd part is the bill: Maine premiums average below the national number anyway.
How to shop for coverage in Maine
A Maine minimum policy already contains what careful riders elsewhere buy deliberately, so shopping here is about administration, not acquisition. Two things the quote engine will not surface are worth interrogating. First, the winter arrangement: what happens to the policy from November to April, whether comprehensive stays live on the stored bike, and how the seasonal billing works. Second, where your uninsured-motorist limits land relative to your liability limits, since that ratio decides how well the policy handles the other driver’s thin coverage.
Carriers confirmed to write motorcycle coverage in Maine include Allstate, GEICO, Harley-Davidson, Liberty Mutual, Markel, Nationwide, Progressive, State Farm, and USAA. That list is alphabetical, not a ranking — availability is a fact, not an endorsement, and several regional insurers write here too; confirm a carrier serves your ZIP when you quote.
Maine coverage requirements
The package has four mandatory parts. Liability of 50/100/25 is the spine: $50,000 for one person’s injuries, $100,000 for everyone injured in one crash, $25,000 for property [29-A M.R.S. § 1605, 2026]. Onto that, the same statute bolts $2,000 of medical-payments coverage, and Maine’s insurance code adds uninsured and underinsured-motorist protection to every policy sold in the state, at limits equal to the liability limits you selected unless you turn the match down in a signed writing [24-A M.R.S. § 2902, 2026]. Nationally this is the top tier, and it has grown by one: Alaska has long required the same 50/100/25 [Insurance Information Institute, 2026], and Virginia moved to those limits for policies effective January 1, 2025 [Virginia Department of Motor Vehicles, 2026]. Neither pairs the floor with mandatory med-pay; that piece is Maine’s alone.
What the package still is not is coverage for your own machine. Every dollar above describes other people’s bodies, other people’s fenders, and your medical bills only to $2,000. Collision and comprehensive remain a choice, though a lender takes the choice away on a financed bike, and the requirements guide sorts out which layer answers which crash.
One comparison worth a minute: next door, New Hampshire mandates no insurance at all for most riders, and the state directory lines Maine’s floor up against the rest. Cross the Piscataqua and the legal floor drops from the nation’s highest to zero.
Maine helmet law
Maine keys its helmet requirement to experience as much as age. Four groups must wear protective headgear: riders under 18, anyone operating on a learner’s permit, any operator within one year of passing the motorcycle driving test, and every passenger of an operator who is required to wear one [29-A M.R.S. § 2083, 2026]. The headgear itself must meet ANSI Z90.1 or the federal FMVSS 218 standard; a DOT-labeled lid clears it.
The one-year clock is the piece riders overlook. A 45-year-old who passes the road test in June is a mandatory-helmet rider until the following June, and so is anyone on the seat behind them. After that, Maine leaves the decision to the adult on the bike. The policy implication cuts one way: the mandatory med-pay layer is $2,000, and that does not go far in a trauma bay.
Lane-splitting legality in Maine
The prohibition is written in plain words: a person may not operate a motorcycle between lanes of traffic or between adjacent lines or rows of vehicles [29-A M.R.S. § 2062, 2026]. The same section is generous inside the lane. A motorcycle is entitled to a lane’s full width, and two may ride abreast, which covers most of what Maine group riding actually involves. But the gap between a stopped log truck and the centerline is not a lane, and filtering through it is a citable moving violation. Maine has adopted no low-speed filtering exception.
All that mandated coverage costs less than the national average buys elsewhere: a standard Maine rider prices out around $320 a year for full coverage and $120 for minimum limits, versus $364 nationally (MoneyGeek, 2026). They rank states by running one rider profile everywhere, so read them as Maine’s placement, not a forecast of your bill. Two Maine-specific notes on reading them: the “minimum” here buys far more protection than a minimum policy in a 25/50 state, and an annual figure spreads oddly across a season that realistically runs May to October. The cost guide covers the levers that move an individual quote.
Maine-specific considerations
Winter is the underwriting event. A Maine bike spends roughly half the year parked, and the difference between a policy that handles that well and one that does not is worth real money. The arrangement to ask for keeps comprehensive alive on the stored machine — theft and fire ignore the calendar — while suspending the collision coverage you cannot use. Get the mechanics in writing, and do not solve winter by cancelling: a lapse reads as a lapse when you reinsure in April, and the surcharge can outlive the savings.
The mandatory uninsured-motorist coverage earns its keep for a structural reason: Maine’s floor is high, but nothing forces the out-of-state driver who hits you to carry Maine-sized limits. UM at 50/100 or better makes the other driver’s thin policy your insurer’s problem instead of your own. Riders with real assets often step liability up to 100/300, because $100,000 per accident is still exhaustible by one serious multi-party crash.
