Multi-Car Liability Requirements in South Carolina
South Carolina 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—the same minimums as a single-vehicle policy. The state uses a fault-based system, meaning the at-fault driver's liability coverage pays for the other party's damages. Uninsured motorist coverage is required, and the multi-car discount applies when all vehicles sit on the same policy under the same garaging address.

Multi-car costs in South Carolina depend on the vehicles you're insuring, the drivers on the policy, the coverage selected per vehicle, and which carrier's multi-car discount structure fits your household. The state's 25/50/25 liability floor is the starting point for every vehicle, and adding collision or comprehensive to one vehicle raises that vehicle's cost without changing the others.
What Affects Your Rate
- South Carolina's 25/50/25 liability minimum applies to every vehicle on the policy, so adding a third car adds a third set of minimums before the multi-car discount.
- The multi-car discount in South Carolina typically requires all vehicles on the same policy and the same garaging address; vehicles garaged at different addresses may not qualify.
- Each vehicle's coverage level—liability only or full coverage—affects that vehicle's premium independently; the multi-car discount applies to the total policy cost.
- Among the 22 carriers writing in South Carolina, multi-car discount structures vary: some give a larger discount when all vehicles carry full coverage, others give the same discount regardless.
- South Carolina's 10.3% uninsured motorist rate means uninsured motorist coverage is required at your liability limits, adding to the cost of every vehicle on the policy.
- Combining two separate policies into one multi-car policy in South Carolina eliminates duplicate policy fees and earns the multi-car discount, but the total premium depends on the vehicles and drivers being combined.

Multi-Car Policy Structure
A multi-car policy puts two or more vehicles on one policy, each carrying its own liability and physical damage coverage, while the whole policy earns the multi-car discount. Each vehicle can carry liability only or full coverage.
Adding a Vehicle to Your Policy
Adding a vehicle to an existing South Carolina multi-car policy mid-term re-rates the entire policy, recalculating the multi-car discount across all vehicles. The new vehicle's premium and the recalculated discount change the total cost immediately.
Liability Insurance Per Vehicle
Every vehicle on a South Carolina multi-car policy carries its own 25/50/25 liability minimum. Two cars means two sets of minimums, not one shared limit. The multi-car discount reduces the total premium, but each vehicle's liability floor stays the same.
Full Coverage on Select Vehicles
Each vehicle on a multi-car policy can carry its own level of physical damage coverage—liability only on an older car, collision and comprehensive on a financed vehicle. The multi-car discount applies to the whole policy regardless of which vehicles carry full coverage.
Uninsured Motorist Coverage
South Carolina requires uninsured motorist coverage at the same limits as your liability coverage. With 10.3% of South Carolina motorists uninsured as of 2023, this coverage protects every vehicle on your multi-car policy when an at-fault driver has no insurance.
Combining Two Household Policies
Combining two separate South Carolina policies into one multi-car policy after marriage or a household move eliminates duplicate policy fees and earns the multi-car discount, but the total premium depends on the vehicles and drivers being combined.
