Multi-Car Liability Requirements in North Dakota
Every vehicle on a North Dakota multi-car policy must carry the state's 25/50/25 liability minimum: $25,000 bodily injury per person, $50,000 bodily injury per accident, and $25,000 property damage. North Dakota also requires personal injury protection and uninsured motorist coverage on every vehicle. The multi-car discount applies when all vehicles sit on the same policy and typically share a garaging address, but each vehicle can carry its own coverage level above the minimum.

Multi-car policy cost in North Dakota depends on the number of vehicles, the drivers assigned to each one, the coverage selected per vehicle, and the multi-car discount. Adding a vehicle mid-term re-rates the entire policy rather than adding a flat monthly amount, and combining two household policies after a marriage or move-in changes both the discount and the per-vehicle premium.
What Affects Your Rate
- The number of vehicles on the policy — North Dakota carriers re-rate the entire policy when you add or remove a vehicle, and the multi-car discount scales with vehicle count.
- The coverage selected per vehicle — one vehicle can carry liability only while another carries full coverage with collision and comprehensive, and the policy premium reflects the sum of per-vehicle coverages.
- The drivers assigned to each vehicle — North Dakota carriers assign a primary driver to each vehicle, and a household with a teen driver assigned to one vehicle and an experienced driver assigned to another will see different per-vehicle premiums.
- The multi-car discount structure — among carriers writing in North Dakota, the discount typically requires the same policy and garaging address, and some carriers give the full discount only when all vehicles are titled to the same person.
- The garaging address — North Dakota's vehicle theft rate of 187.5 per 100,000 population as of 2024 varies by city, and a Fargo garaging address may produce different per-vehicle premiums than a Bismarck address on the same multi-car policy.
- The liability limits above the minimum — raising one vehicle's limits from 25/50/25 to 100/300/100 increases that vehicle's premium but does not affect the other vehicles' premiums or the multi-car discount.

Multi-Vehicle Policy Structure
A multi-car policy puts two or more owned vehicles on one policy, each carrying its own coverage level, and earns the multi-car discount when all vehicles share the same policy and typically the same garaging address.
Liability Coverage Per Vehicle
Each vehicle on a North Dakota multi-car policy must carry at least 25/50/25 liability, and you can raise the limits on one vehicle without changing the others.
Adding a Vehicle Mid-Term
Adding a vehicle to an existing North Dakota multi-car policy re-rates the entire policy based on the new vehicle count, the coverage selected for the new vehicle, and the updated multi-car discount.
Combining Household Policies
Combining two separate policies after a marriage or household member moving in puts all vehicles on one North Dakota policy and applies the multi-car discount to the full vehicle count.
Uninsured Motorist Coverage
North Dakota requires uninsured motorist coverage on every vehicle, and it applies per vehicle rather than as a single policy-wide limit on a multi-car policy.
Full Coverage on Select Vehicles
Full coverage adds collision and comprehensive to the liability minimum, and on a North Dakota multi-car policy you can carry full coverage on one vehicle and liability only on another.
