Multi-Car Liability Requirements in Maine
Maine requires every vehicle on a multi-car policy to carry $50,000 bodily injury per person, $100,000 bodily injury per accident, $25,000 property damage, plus Personal Injury Protection and uninsured motorist coverage. The multi-car discount typically requires all vehicles on the same policy and the same garaging address. Maine uses a modified comparative fault system, meaning each vehicle's liability coverage responds when the insured driver is at fault.

Multi-car premiums in Maine depend on the number of vehicles, the drivers assigned to each, the coverage selected per vehicle, and the multi-car discount earned by keeping all vehicles on one policy. Maine's average annual auto insurance expenditure per insured vehicle was $1,749.22 in 2023, but adding a second or third vehicle to an existing policy costs less per vehicle than insuring each separately due to the multi-car discount.
What Affects Your Rate
- Maine's required PIP and uninsured motorist coverage add to the base premium for every vehicle on a multi-car policy, regardless of how many vehicles you insure together.
- The multi-car discount in Maine typically requires all vehicles to share the same garaging address and sit on the same policy, so vehicles garaged at different addresses may not qualify.
- Each vehicle on a Maine multi-car policy can carry its own deductible for collision and comprehensive coverage, allowing you to choose higher deductibles on older vehicles and lower deductibles on newer ones.
- Maine's 5.7% uninsured motorist rate as of 2023 makes uninsured motorist coverage more valuable on a multi-car policy because the coverage stacks across vehicles in some claim scenarios.
- Carriers writing in Maine including Progressive, Geico, and State Farm structure the multi-car discount differently, so comparing carriers for the specific vehicles and drivers in your household identifies the lowest total premium.
- Adding a third or fourth vehicle to a Maine multi-car policy increases the total premium but decreases the per-vehicle cost due to the multi-car discount, making it cheaper to insure all vehicles together than separately.

Multi-Car Policy Structure
A multi-car policy in Maine puts two or more vehicles on one policy, each carrying at least the state's 50/100/25 liability minimum plus PIP and uninsured motorist coverage. Each vehicle can carry its own level of collision and comprehensive coverage.
Adding a Vehicle to an Existing Policy
Adding a vehicle mid-term in Maine re-rates the entire policy immediately, applying the multi-car discount to all vehicles and adjusting the premium based on the new vehicle's profile and the household's driving record.
Combining Household Policies
Merging two separate Maine policies into one multi-car policy earns the multi-car discount on every vehicle and consolidates billing, but typically requires all vehicles to share the same garaging address.
Liability Coverage Per Vehicle
Every vehicle on a Maine multi-car policy must carry at least 50/100/25 liability plus PIP and uninsured motorist coverage. You can increase liability limits on any vehicle without changing the others.
Full Coverage on Select Vehicles
Full coverage adds collision and comprehensive to the required liability, PIP, and uninsured motorist coverage. On a Maine multi-car policy, you can carry full coverage on financed vehicles and liability-only on older paid-off vehicles.
Uninsured Motorist Coverage Stacking
Maine requires uninsured motorist coverage on every vehicle. On a multi-car policy, the coverage may stack across vehicles in some claim scenarios, providing higher total limits when you are hit by an uninsured driver.
