The Registration Blocker
You purchased a vehicle in New Hampshire, Massachusetts, or another state, and now you need Maine plates. The Bureau of Motor Vehicles will not register the car until you present proof of insurance that meets Maine's mandatory coverage structure: $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 covers only the minimum liability required in the state where you bought the car, Maine will reject the registration application.
This article walks the specific steps to add Maine-compliant coverage to an out-of-state vehicle, the documentation the BMV requires, and the timing windows that determine whether you can drive the car legally while you complete the process.

$50,000/$100,000/$25,000
Maine requires $50,000 bodily injury per person, $100,000 per accident, and $25,000 property damage on every registered vehicle. These limits apply whether the car was purchased in-state or out of state.

What Maine Requires That Other States Do Not
Maine mandates personal injury protection and uninsured motorist coverage on every auto policy. Many states do not require PIP, and some allow drivers to reject UM coverage in writing. A policy written in a state without these mandates will not satisfy Maine's registration requirements, even if the liability limits meet or exceed Maine's minimums.
The BMV verifies coverage electronically through the Maine Insurance Verification System. When you submit a registration application, the system checks that your policy includes the required coverages. A liability-only policy triggers an immediate rejection, and the BMV will not issue plates until the deficiency is corrected.
If you already insure other vehicles in Maine, adding the out-of-state car to your existing policy automatically applies Maine's mandatory coverage structure. If you do not currently have a Maine policy, you must purchase one that includes PIP and UM before the BMV will register the vehicle.
A policy that meets another state's requirements does not automatically meet Maine's. The BMV rejects registrations when PIP or UM coverage is absent, regardless of liability limits.
Adding the Vehicle to Your Existing Maine Policy
Contact your carrier as soon as you complete the purchase. Provide the vehicle identification number, the bill of sale, and the odometer reading. The carrier will add the vehicle to your policy effective immediately and issue an updated declarations page showing the new car with Maine-compliant coverage. Most carriers process the addition within one business day; some offer same-day amendments if you call during business hours.
The BMV requires the updated declarations page at registration. Bring the original or a printed copy showing the vehicle, the policy number, the effective date, and the coverage limits. The electronic verification system cross-references the paper document, so the policy must be active in the system before you submit the application. If the carrier has not yet transmitted the update to the state database, the BMV will reject the registration even if you present the declarations page.

Purchasing a New Policy for the Out-of-State Vehicle
If you do not currently insure a vehicle in Maine, you must purchase a new policy before registering the out-of-state car. The policy must include Maine's mandatory coverages and list your Maine address as the garaging location. Carriers writing in Maine include Allstate, Geico, Progressive, State Farm, and others; 16 carriers in the injected roster write standard or preferred policies in the state.
Request quotes from at least three carriers. Provide the VIN, the purchase price, the bill of sale date, and your Maine address. The carrier will issue a policy with an effective date you specify; choose a date that aligns with your planned registration appointment. The carrier transmits the policy to Maine's verification system within 24 to 48 hours of issuance, so schedule your BMV visit at least two business days after the policy effective date to ensure the system reflects the coverage.
If you own multiple vehicles and plan to register all of them in Maine, add every car to the same policy. Maine's multi-vehicle structure applies the mandatory coverages to each vehicle on the policy, and most carriers offer a multi-car discount when two or more vehicles share one policy. The discount typically requires that all vehicles be garaged at the same address and titled to the same household members.

Temporary Coverage and the Drive-Home Window
Maine does not issue temporary registration permits for newly purchased vehicles. You cannot legally drive the out-of-state car in Maine until it carries Maine plates and Maine-compliant insurance. If you need to drive the vehicle from the purchase location to your Maine address, verify that your existing policy or the seller's policy covers the transit period. Many carriers extend coverage to a newly acquired vehicle for a limited window, typically 14 to 30 days, but only if you already insure at least one vehicle with that carrier.
Once the car reaches your Maine address, do not drive it on public roads until you complete the registration and receive plates. The BMV will not register the vehicle without proof of Maine-compliant coverage, and driving an unregistered car in Maine subjects you to fines and potential impoundment. Add the vehicle to your policy or purchase a new policy before you schedule the registration appointment, and confirm that the carrier has transmitted the coverage to the state verification system.
What to Bring to the Bureau of Motor Vehicles
The BMV requires the vehicle title, a bill of sale, proof of Maine residency, and proof of insurance. The insurance document must be the current declarations page showing the vehicle, the policy number, the effective date, and coverage that meets or exceeds Maine's minimums. If the vehicle is financed, bring the lienholder's name and address; the BMV will note the lien on the title and registration.
The BMV charges a registration fee based on the vehicle's model year and weight. Pay the fee at the time of registration; the BMV accepts cash, check, or card at most branches. If the electronic verification system does not reflect your policy when you submit the application, the BMV will reject the registration and you will need to return after the carrier transmits the update. Call your carrier before the appointment to confirm that the policy is active in Maine's system.
