Multi-Car Liability Requirements in South Carolina

South Carolina also requires uninsured motorist coverage on every vehicle. The multi-car discount applies when all vehicles sit on the same policy and typically requires a shared garaging address, but each vehicle can carry its own level of collision and comprehensive coverage while earning the discount.

Bodily Injury Liability

Every vehicle on your South Carolina multi-car policy must carry this minimum bodily injury liability. If you own a sedan and a truck on one policy, both carry the 25/50 floor, though you can purchase higher limits for one or both vehicles. Carriers including State Farm, Geico, and Progressive write multi-car policies in South Carolina and allow per-vehicle limit customization while preserving the multi-car discount.

Property Damage Liability

A multi-car policy covers every vehicle at this floor, and adding a third or fourth vehicle to the policy re-rates the entire policy rather than adding a flat amount. Carriers writing in South Carolina including Allstate, Farmers, and Nationwide structure multi-car policies this way.

Uninsured Motorist Coverage

South Carolina requires uninsured motorist coverage on every vehicle on a multi-car policy. The multi-car discount applies to the entire policy premium including UM coverage.

Multi-Car Discount Requirement

Carriers including Geico, Progressive, State Farm, and National General write multi-car policies in South Carolina and apply the discount when these conditions are met. Adding a vehicle mid-term re-rates the policy immediately, and the discount scales with the number of vehicles on the policy.

Per-Vehicle Physical Damage Coverage

Each vehicle on a South Carolina multi-car policy can carry its own level of collision and comprehensive coverage. You can insure a newer car with full coverage and an older car with liability only, both on the same policy earning the multi-car discount. Each vehicle that carries physical-damage coverage has its own deductible, and the discount applies to the total policy premium.
