The Grace Period Reality
You can keep your out-of-state auto insurance policy active after moving to Maine, but only until your next vehicle registration renewal with the Maine Bureau of Motor Vehicles. At that point, the state requires proof of a policy that meets Maine's mandatory minimums: $50,000 bodily injury per person, $100,000 per accident, $25,000 property damage, plus Personal Injury Protection and Uninsured Motorist coverage. If your current policy does not carry those minimums or those coverages, you will face a gap at registration time.
The confusion arises because many states allow lower liability limits than Maine, and some do not mandate PIP or UM coverage at all. A policy that satisfied your prior state's requirements may fall short of Maine's, and the BMV will not renew your registration without proof of compliant coverage. This article clarifies what Maine actually requires, when the deadline hits, and how to structure your coverage across the transition without a lapse.

$50,000/$100,000/$25,000
Maine requires $50,000 bodily injury coverage per person, $100,000 per accident, and $25,000 property damage. PIP and Uninsured Motorist coverage are also mandatory. Your out-of-state policy must meet or exceed these limits to satisfy registration requirements.

What Maine Requires From Every Policy
Maine law mandates five coverage components on every registered vehicle: bodily injury liability at $50,000 per person and $100,000 per accident, property damage liability at $25,000, Personal Injury Protection, and Uninsured Motorist coverage. These are not optional. The BMV will not issue or renew a registration without proof that all five are active on the vehicle.
Many states require lower liability limits. If your prior state's minimum was $25,000/$50,000/$25,000, your current policy may not meet Maine's bodily injury threshold. Similarly, if your prior state did not mandate PIP or UM, your policy may lack those coverages entirely. The out-of-state carrier can often add the missing coverages or raise the limits, but you must request the change before your Maine registration renewal date.
The BMV does not automatically notify you of the coverage gap. You discover it when you attempt to renew registration and the system rejects your proof of insurance. At that point, you cannot legally drive the vehicle until you secure compliant coverage and re-submit proof to the BMV.
Your registration renewal is the hard deadline. The BMV will not renew without proof of a policy meeting all five Maine coverage mandates.
How to Transition Your Policy

Contact your current carrier and request a policy review against Maine's minimums. Ask specifically whether your policy includes PIP and UM coverage, and whether your bodily injury limits meet $50,000/$100,000. If the carrier writes policies in Maine, they can typically add the missing coverages and raise the limits with a mid-term endorsement. The premium will adjust to reflect Maine's higher requirements and your new garaging address. Request a revised declarations page showing the updated limits and coverages, and confirm the carrier will file proof of insurance electronically with the Maine BMV.
If your carrier does not write in Maine or cannot modify the policy to meet the state's requirements, you must switch carriers before your registration renewal. Compare carriers licensed in Maine that write policies meeting the mandatory minimums. Request quotes that include PIP and UM coverage at the required levels, and confirm the new carrier will file proof of insurance with the BMV upon binding.
Registration Renewal and the Coverage Deadline
Maine vehicle registrations renew on a cycle set by the BMV, typically annually or biennially depending on the vehicle type and registration class. Your renewal notice will arrive by mail approximately 30 days before the expiration date. The notice does not include a coverage compliance check; that happens when you submit payment and proof of insurance to renew.
If your out-of-state policy does not meet Maine's requirements at the time of renewal, the BMV system will reject the proof of insurance and decline the renewal. You cannot drive the vehicle legally once the registration expires. To avoid this, review your policy against Maine's minimums at least 60 days before your first Maine registration renewal, and make any necessary changes or carrier switches with time to spare.
New residents often assume they have 30 or 60 days after moving to update their insurance. Maine law does not specify a grace period by calendar days; the deadline is your registration renewal. If you moved to Maine one month before your registration expires, you have one month. If you moved six months before, you have six months. The registration renewal is the trigger, not the move date.
Carriers Writing in Maine
16 carriers
At least 16 major carriers write auto insurance policies in Maine, including Allstate, Geico, Progressive, State Farm, and USAA. Compare carriers that offer policies meeting Maine's mandatory PIP and UM requirements if your current carrier does not write in the state.
What Happens If Your Policy Falls Short
If the BMV rejects your proof of insurance at registration renewal because your policy does not meet Maine's minimums, your registration expires and you cannot legally drive the vehicle. Driving with an expired registration is a traffic violation subject to fines and potential vehicle impoundment.
To resolve the situation, you must secure a compliant policy, obtain a declarations page or electronic proof of insurance showing all five required coverages at the mandatory limits, and submit that proof to the BMV along with the registration renewal fee and any applicable late fees or reinstatement fees. The process can take several business days, during which the vehicle remains unregistered and undrivable.
Compare Carriers Before Your Deadline
Do not wait until your registration renewal notice arrives to address your coverage. Review your current policy's declarations page now. Check whether it lists Personal Injury Protection and Uninsured Motorist coverage, and whether the bodily injury limits meet $50,000 per person and $100,000 per accident. If any component is missing or falls short, contact your carrier immediately to request the necessary changes.
If your carrier cannot modify the policy or does not write in Maine, compare carriers licensed in the state that offer policies meeting the mandatory requirements. Request quotes that explicitly include PIP and UM coverage, and confirm the carrier will file proof of insurance electronically with the Maine BMV. Bind the new policy with an effective date that ensures no gap between your out-of-state policy's cancellation and the new policy's start, and request confirmation of the BMV filing within 24 hours of binding. That confirmation is your proof that the state has received your insurance information and will accept it at registration renewal.
