Multi-Car Liability Requirements in Idaho
Every vehicle on a Idaho multi-car policy must carry at least $25,000 bodily injury per person, $50,000 bodily injury per accident, and $15,000 property damage—the state's minimum liability floor. Idaho does not mandate uninsured motorist or personal injury protection coverage, so those remain optional additions. The multi-car discount typically requires all vehicles on the same policy and often the same garaging address; how the vehicles are titled and where they're garaged determines whether the discount applies.

Multi-car policy cost in Idaho depends on the number of vehicles, the drivers assigned to each, the coverage level selected per vehicle, and the multi-car discount the carrier applies. Each vehicle on the policy carries its own liability minimum—$25,000/$50,000/$15,000—and can carry its own collision, comprehensive, and deductible. Adding a vehicle mid-term re-rates the entire policy rather than adding a flat amount, so the discount applies immediately.
What Affects Your Rate
- Each vehicle on a Idaho multi-car policy must carry the $25,000/$50,000/$15,000 liability minimum, so the number of vehicles directly multiplies the base liability cost before the multi-car discount applies.
- The multi-car discount in Idaho typically requires all vehicles on the same policy and the same garaging address; vehicles garaged at different addresses may not qualify for the discount with most carriers.
- Adding a vehicle mid-term re-rates the entire Idaho policy rather than adding a flat amount, so the multi-car discount applies immediately to the new vehicle count.
- Among carriers writing in Idaho, Geico, Progressive, State Farm, Allstate, and Farmers all offer multi-car discounts, though the specific discount percentage varies by carrier and is not published.
- Idaho does not mandate uninsured motorist coverage, so adding UM/UIM to each vehicle on a multi-car policy is optional and increases the per-vehicle cost.

Multi-Car Policy Structure
A multi-car policy puts two or more owned vehicles on one policy, with each vehicle carrying its own coverage level and the whole policy earning the multi-car discount. Each vehicle must carry at least the state liability minimum.
Liability Insurance Per Vehicle
Each vehicle on a multi-car policy carries its own liability coverage at or above the state minimum. The liability limit applies per vehicle, not per policy, so each vehicle's limit is separate.
Full Coverage on Select Vehicles
Full coverage—liability plus collision and comprehensive—can be applied to individual vehicles on a multi-car policy while other vehicles carry liability only. Each vehicle's deductible applies separately.
Uninsured Motorist Coverage
Uninsured and underinsured motorist coverage pays when an at-fault driver lacks coverage. It's optional in Idaho and can be added to all vehicles on a multi-car policy or select vehicles.
Adding a Vehicle Mid-Term
Adding a vehicle to an existing multi-car policy mid-term re-rates the entire policy to reflect the new vehicle count and the multi-car discount. The discount applies from the date the vehicle is added.
Combining Household Policies
When two households combine, the multi-car discount typically requires all vehicles to garage at the same address. Vehicles titled to different household members can share one policy if they meet the garaging requirement.
