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 minimum liability floor.

Multi-car cost in South Carolina depends on the vehicles you insure, the drivers on the policy, the coverage level selected per vehicle, and the multi-car discount the carrier offers. Adding a second vehicle to an existing South Carolina policy re-rates the entire policy rather than adding a flat monthly amount, so the discount and the new vehicle's profile both affect the total.
What Affects Your Rate
- South Carolina's $25,000/$50,000/$25,000 minimum liability applies to every vehicle on the policy—raising limits on one vehicle does not change the requirement for the others.
- The multi-car discount in South Carolina typically requires every vehicle on the same policy and the same garaging address; carriers writing here vary in whether they allow different titleholders.
- Each vehicle on the policy carries its own coverage level—liability-only, or liability plus collision and comprehensive—and its own deductible if physical damage coverage applies.
- Adding a vehicle mid-term re-rates the entire South Carolina policy rather than adding a flat monthly amount, so the new vehicle's profile and the adjusted multi-car discount both affect the total.
- South Carolina recorded 1.72 traffic fatalities per 100 million vehicle miles traveled in 2023, and 217.3 motor vehicle thefts per 100,000 population in 2024—both factors carriers weigh when pricing multi-car policies.
- With 10.3% of South Carolina motorists uninsured as of 2023, carriers price uninsured motorist coverage into every multi-car policy, and the state mandates it on every vehicle unless you decline in writing.
