Multi-Car Liability Requirements in South Carolina
South Carolina requires every vehicle on a multi-car policy to carry at least $25,000 bodily injury per person, $50,000 bodily injury per accident, and $25,000 property damage—the 25/50/25 minimum. The state operates under a fault-based system, meaning the at-fault driver's liability coverage pays for injuries and damage in an accident. Uninsured motorist coverage is mandatory, protecting you when the other driver lacks insurance. The multi-car discount applies when all vehicles sit on the same policy, typically requiring a shared garaging address.

Multi-car policy costs in South Carolina depend on the vehicles you insure, the drivers on the policy, and the coverage level you select for each vehicle. The multi-car discount reduces the total premium when all vehicles sit on one policy, but adding a vehicle mid-term re-rates the entire policy based on the new vehicle's profile. South Carolina's 10.3% uninsured motorist rate and mandatory uninsured motorist coverage requirement add to the base cost.
What Affects Your Rate
- South Carolina's mandatory uninsured motorist coverage adds to the base premium for every vehicle on a multi-car policy, with 10.3% of state motorists uninsured as of 2023.
- The multi-car discount applies when all vehicles sit on the same policy, typically requiring a shared garaging address—carriers including Geico, Progressive, State Farm, and USAA write multi-car policies statewide.
- Each vehicle's profile—year, make, model, annual mileage, and garaging ZIP code—shapes the per-vehicle premium, and adding a vehicle mid-term re-rates the entire policy rather than adding a flat amount.
- Collision and comprehensive coverage can differ per vehicle on a South Carolina multi-car policy, so you can carry full coverage on a financed vehicle and liability-only on an older paid-off car while earning the same multi-car discount.
- South Carolina's fault-based system means the at-fault driver's liability coverage is the primary payer, making adequate liability limits critical when multiple vehicles and drivers share one policy.
- Accidents on your record increase the base premium for every vehicle on a South Carolina multi-car policy, and the surcharge applies to the combined policy rather than per vehicle.

Multi-Car Policy Structure
A multi-car policy puts two or more owned vehicles on a single South Carolina policy, earning the multi-car discount when all vehicles share the same policy and typically the same garaging address. Each vehicle carries at least the state's 25/50/25 liability minimum, and coverage can differ per vehicle.
Liability Coverage Per Vehicle
Every vehicle on a South Carolina multi-car policy must carry at least $25,000 bodily injury per person, $50,000 per accident, and $25,000 property damage. This is the legal floor, and higher limits protect household assets when multiple vehicles and drivers share one policy.
Uninsured Motorist Coverage
South Carolina requires uninsured motorist coverage on every multi-car policy, matching your bodily injury liability limits unless you reject it in writing. This protects you when an at-fault driver lacks insurance, covering injuries to you and your passengers.
Full Coverage Per Vehicle
Full coverage adds collision and comprehensive to South Carolina's liability minimum, paying for damage to your own vehicle. On a multi-car policy, each vehicle can carry its own level of coverage—one car with full coverage, another with liability only—while earning the same multi-car discount.
Adding a Vehicle Mid-Term
Adding a vehicle to an existing South Carolina multi-car policy mid-term re-rates the entire policy based on the new vehicle's profile and the total vehicle count. The multi-car discount adjusts immediately, and the new vehicle must carry at least the 25/50/25 liability minimum.
Combining Household Policies
Marriage or cohabitation often triggers combining two separate South Carolina policies into one multi-car policy. Most carriers require a shared garaging address and both vehicles titled to household members on the same policy to earn the full multi-car discount.
