The Registration Clock Starts When You Arrive
You moved to Maine last week, your household owns two cars, and the DMV told you that you have 30 days to register both vehicles in-state. Your current auto policy covers both cars under one multi-vehicle policy from your previous state, and you assumed you could keep that coverage while you handled the registration paperwork. Then you read Maine's insurance requirements and realized your policy might not meet the state's mandatory coverage rules.
Maine requires personal injury protection and uninsured motorist coverage on every registered vehicle. Many states do not mandate both coverages, so if your current policy was written in a state without those requirements, your existing multi-car policy may not satisfy Maine's rules even though it's active and valid elsewhere. This article walks you through exactly what Maine requires, how to confirm whether your current policy meets those requirements, and what happens when you register multiple vehicles on a new Maine policy.

Maine requires $50,000 bodily injury per person, $100,000 bodily injury per accident, and $25,000 property damage. Personal injury protection and uninsured motorist coverage are also mandatory, regardless of your prior state's rules.

What Maine Requires That Your Current Policy May Lack
Maine's mandatory coverage list includes liability limits, personal injury protection, and uninsured motorist coverage. The liability minimums are $50,000 per person for bodily injury, $100,000 per accident for bodily injury, and $25,000 for property damage. If your previous state required lower limits, your current policy may meet those lower thresholds but fall short of Maine's.
The bigger structural difference is PIP and uninsured motorist coverage. Maine mandates both on every policy. Personal injury protection pays your medical expenses and lost wages after an accident regardless of fault. Uninsured motorist coverage protects you when the at-fault driver has no insurance or insufficient coverage. Many states make one or both of these coverages optional, so a policy written in a state without those mandates will not include them unless you added them voluntarily.
When you register your vehicles in Maine, the Bureau of Motor Vehicles verifies that your insurance meets state requirements. If your current multi-car policy lacks PIP or UM coverage, the BMV will not complete registration until you provide proof of a compliant policy. You cannot register first and fix the insurance later.
Your out-of-state multi-car policy will not satisfy Maine registration requirements if it lacks personal injury protection or uninsured motorist coverage, even if it meets your previous state's rules.
How to Confirm Your Current Policy Meets Maine Rules
The declarations page lists every coverage on your policy, the limits for each coverage, and the vehicles covered. Look for a line item labeled personal injury protection or PIP, and another labeled uninsured motorist or UM. If both appear and the liability limits meet or exceed Maine's minimums, your current carrier may be able to endorse the policy to reflect your Maine address without rewriting it. Call your carrier and ask whether they write policies in Maine and whether your current policy can be updated to meet Maine requirements.
If either PIP or UM is missing, or if your carrier does not write policies in Maine, you need a new policy from a Maine-licensed carrier before you register your vehicles. When you own multiple cars, the new policy must cover all vehicles garaged at your Maine address to preserve the multi-car discount. Most carriers require every vehicle on a multi-car policy to share the same garaging address and the same primary policyholder, so if your household includes vehicles titled to different people, confirm with the carrier how they structure multi-vehicle policies before you bind coverage.

The 30-Day Registration Window and How It Affects Your Insurance Timeline
Maine law requires new residents to register their vehicles within 30 days of establishing residency. The BMV considers you a resident when you take a job in Maine, enroll your children in a Maine school, or register to vote. The 30-day clock starts from that event, not from the day you physically move into your new home.
If you miss the 30-day window, you cannot legally drive your unregistered vehicles on Maine roads. The consequence is not just a registration penalty — if you are stopped or involved in an accident while driving an unregistered vehicle, your insurance claim may be denied because the vehicle was not legally operated. This means you need compliant insurance in place before the registration deadline, not after.
When you own two or more vehicles, the registration timeline applies to each vehicle individually. You cannot register one car first and delay the second. Both vehicles must be insured under a Maine-compliant policy and registered within the same 30-day window. If your current carrier cannot endorse your policy to meet Maine requirements, start shopping for a new multi-car policy as soon as you know your move date.

How Adding Maine-Mandated Coverages Changes Your Multi-Car Policy Cost
Adding personal injury protection and uninsured motorist coverage to a multi-car policy increases the total premium because each coverage applies per vehicle. A two-car household pays for PIP and UM on both cars, and a three-car household pays for all three. The increase is not a flat add-on — the cost of PIP and UM varies by the number of vehicles, the coverage limits you select, and the carrier's rate structure.
The multi-car discount offsets part of that increase. Most Maine carriers apply a multi-vehicle discount when you insure two or more cars on the same policy, and the discount typically increases as you add more vehicles. The discount applies to the base premium before PIP and UM are added, so the final cost reflects both the mandatory coverage increase and the multi-car savings. A household moving from a state without PIP or UM mandates will see a higher total premium in Maine, but insuring multiple cars on one policy keeps that increase lower than insuring each car separately.
What Happens If You Keep Your Out-of-State Policy After Moving
Some new residents keep their out-of-state policy active after moving to Maine because they assume the policy remains valid as long as premiums are paid. That assumption is wrong. Auto insurance policies are written for a specific garaging address, and when you move to a new state, the garaging address changes. Most carriers require you to notify them of an address change within 30 days, and if your new address is in a state where the carrier is not licensed, the policy may be canceled.
Even if your carrier is licensed in Maine and agrees to update your address, the policy must be rewritten to meet Maine's mandatory coverage requirements. If you do not add PIP and UM, the policy will not satisfy Maine registration rules, and the BMV will reject your registration application. Worse, if you are involved in an accident while driving with an out-of-state policy that does not meet Maine requirements, your claim may be denied because the vehicle was not properly insured under state law. Keeping an out-of-state policy after moving does not save money — it creates a coverage gap that leaves you financially exposed.
Compare Maine Carriers and Lock In Coverage Before Registration
Start comparing Maine carriers as soon as you know your move date. Request quotes from at least three carriers that write multi-car policies in Maine, and confirm each quote includes personal injury protection and uninsured motorist coverage at the state-required minimums. When you receive quotes, verify that every vehicle in your household is listed on the same policy — splitting vehicles across separate policies eliminates the multi-car discount and raises your total cost. Bind the new policy before your registration appointment so you have proof of Maine-compliant insurance when you walk into the BMV.
