Multi-Car Liability Requirements in New Hampshire
New Hampshire requires every vehicle on a multi-car policy to carry $25,000 bodily injury per person, $50,000 bodily injury per accident, and $25,000 property damage, plus personal injury protection and uninsured motorist coverage. The state operates under a modified comparative fault system. The multi-car discount applies when all vehicles sit on the same policy and typically share a garaging address.

Multi-car cost in New Hampshire depends on the vehicles you're insuring, the drivers on the policy, the coverage level selected per vehicle, and the multi-car discount. Carriers writing in New Hampshire — including Allstate, Geico, Progressive, State Farm, and Farmers — calculate the discount differently, and how the vehicles are titled and garaged changes whether the full discount applies.
What Affects Your Rate
- The multi-car discount in New Hampshire requires every vehicle on the same policy and typically the same garaging address — vehicles titled to different household members may still qualify if they share a garaging location.
- Each vehicle on the policy can carry its own coverage level: one vehicle at liability-only and another with collision and comprehensive, while both earn the multi-car discount.
- New Hampshire's required PIP and uninsured motorist coverage apply to every vehicle on the policy, adding to the base cost regardless of whether a vehicle carries collision or comprehensive.
- With 10% of New Hampshire motorists uninsured as of 2023, the required uninsured motorist coverage protects each vehicle on your multi-car policy when the at-fault driver has no insurance.
- New Hampshire's average annual auto insurance expenditure per insured vehicle was $1,461.47 in 2023, and multi-car policies spread fixed costs across multiple vehicles while earning the discount.
- Adding a vehicle mid-term re-rates the entire policy rather than adding a flat amount, and the multi-car discount recalculates based on the new vehicle count.

Multi-Car Insurance
A multi-car policy covers two or more vehicles on one policy, each carrying its own coverage level, while the whole policy earns the multi-car discount. The discount typically requires the same policy and the same garaging address.
Liability Insurance
Bodily injury and property damage liability coverage pays for injuries and damage you cause to others. New Hampshire requires 25/50/25 on every vehicle, and you can raise limits on individual vehicles without changing coverage on the others.
Uninsured Motorist Coverage
Uninsured motorist coverage protects you when the at-fault driver has no insurance. New Hampshire requires this on every vehicle, and it applies separately to each vehicle on a multi-car policy.
Full Coverage Insurance
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 while both earn the multi-car discount.
