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, and $25,000 property damage. The state also mandates personal injury protection and uninsured motorist coverage. Maine operates under a fault system, so the at-fault driver's liability coverage pays for damages. The multi-car discount applies when all vehicles sit on the same policy and typically share a garaging address.

Multi-car policy costs in Maine depend on the vehicles you insure, the drivers on the policy, and the coverage level selected for each vehicle. The multi-car discount applies when all vehicles share one policy, but the base rate reflects the combined risk profile of every car and driver. Maine carriers re-rate the entire policy when you add or remove a vehicle, so the discount recalculates with each change.
What Affects Your Rate
- Maine's $50,000/$100,000/$25,000 liability minimum applies to every vehicle on the policy, setting the base coverage floor.
- The multi-car discount requires all vehicles on the same policy and typically the same garaging address.
- Each vehicle's make, model, year, and use pattern affects the policy premium independently, so insuring a newer car alongside an older one raises the total cost.
- The number of drivers on the policy and their driving records shape the base rate before the multi-car discount applies.
- Maine's 5.7% uninsured motorist rate and required uninsured motorist coverage add to the per-vehicle premium.
- Collision and comprehensive coverage can differ per vehicle on a multi-car policy, so one car can carry full coverage while another carries liability only.

Multi-Car Policy Structure
A multi-car policy puts two or more vehicles on one policy, each carrying its own coverage level. The multi-car discount applies when all vehicles share the same policy and typically the same garaging address.
Liability Coverage Per Vehicle
Liability insurance pays for injuries and property damage you cause to others in an at-fault accident. Maine requires $50,000/$100,000/$25,000 on every vehicle, including those on multi-car policies.
Adding a Vehicle to Your Policy
Adding a vehicle to an existing Maine policy triggers a full policy re-rate, not a simple add-on charge. The multi-car discount adjusts to reflect the new vehicle count, and the base premium recalculates based on the combined risk of all vehicles and drivers.
Uninsured Motorist Coverage
Uninsured motorist coverage protects you when an at-fault driver lacks insurance. Maine requires this coverage on every vehicle, including those on multi-car policies.
Full Coverage on Select Vehicles
Full coverage combines liability, collision, and comprehensive on a single vehicle. On a multi-car policy, you can carry full coverage on one vehicle and liability only on another, and the multi-car discount still applies to the total policy premium.
Combining Household Policies
When two households combine in Maine, putting all vehicles on one policy earns the multi-car discount if they share a garaging address. Each vehicle can carry different coverage levels, but the discount applies to the total policy premium.
