Multi-Car Liability Requirements in South Carolina
Every vehicle on a South Carolina multi-car policy must carry at least $25,000 bodily injury per person, $50,000 bodily injury per accident, and $25,000 property damage—the state's liability minimum. South Carolina is a fault state, meaning the at-fault driver's liability coverage pays for damages in an accident. Uninsured motorist coverage is required for every vehicle on the policy. The multi-car discount typically requires all vehicles on the same policy and often the same garaging address.

Multi-car policy cost in South Carolina depends on the vehicles you insure, the drivers on the policy, the coverage level selected for each vehicle, and the multi-car discount. Adding a vehicle mid-term re-rates the entire policy rather than adding a flat amount, so the discount applies immediately. Carriers writing in South Carolina—including State Farm, Geico, Progressive, Allstate, and Nationwide—each structure the multi-car discount differently, and the discount size varies by carrier.
What Affects Your Rate
- Each vehicle's year, make, model, and value—newer or higher-value vehicles cost more to insure when you add collision and comprehensive.
- The drivers on the policy—age, driving record, and claims history affect the premium for every vehicle on the multi-car policy.
- The coverage level selected for each vehicle—one vehicle might carry liability only while another carries full coverage, and the multi-car discount applies to the whole policy regardless.
- The multi-car discount size—carriers writing in South Carolina structure the discount differently, and the discount percentage varies by carrier and the number of vehicles on the policy.
- The garaging address—South Carolina's average annual expenditure per insured vehicle was $1,539.47 in 2023, but urban areas with higher theft rates or traffic density cost more than rural counties.
- The South Carolina 25/50/25 liability minimum—every vehicle on the policy must carry at least this floor, and raising limits above the minimum increases the premium for each vehicle that carries higher limits.

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 can carry liability only or liability plus collision and comprehensive, and the discount applies regardless of which vehicles carry physical damage coverage.
Liability Coverage Per Vehicle
Each vehicle on a South Carolina multi-car policy must carry at least the state's 25/50/25 liability minimum—$25,000 bodily injury per person, $50,000 per accident, and $25,000 property damage. Each vehicle's liability coverage applies independently, so one vehicle's claim does not reduce the limit available to another vehicle on the same policy.
Uninsured Motorist Coverage
South Carolina requires uninsured motorist coverage on every vehicle on a multi-car policy. This coverage pays for injuries to you and your passengers when an at-fault driver has no insurance or insufficient coverage to pay your claim.
Full Coverage Per Vehicle
Full coverage on a multi-car policy means adding collision and comprehensive to the liability minimum for one or more vehicles. Collision pays for damage to your vehicle in an accident regardless of fault; comprehensive pays for theft, weather damage, vandalism, and animal strikes. Each vehicle on the policy can carry its own deductible and coverage level.
Adding a Vehicle Mid-Term
Adding a vehicle to an existing South Carolina multi-car policy mid-term re-rates the entire policy rather than adding a flat amount. The multi-car discount adjusts to reflect the additional vehicle, and the new premium takes effect on the date you add the vehicle.
Combining Household Policies
When two South Carolina households combine—after marriage or moving in together—putting all vehicles on one policy earns the multi-car discount if the vehicles share a garaging address. Carriers typically require that all vehicles be titled to household members at the same address to give the full discount.
