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. Uninsured motorist coverage is mandatory. The multi-car discount typically requires all vehicles on the same policy and often the same garaging address, so how the vehicles are titled and where they are garaged affects eligibility.

Multi-car costs in South Carolina are driven by the number of vehicles, the drivers assigned to each vehicle, the coverage selected per vehicle, and the multi-car discount. Adding a vehicle mid-term re-rates the policy rather than adding a flat amount, so the second vehicle's cost depends on the first vehicle's profile and the household's combined driving history.
What Affects Your Rate
- South Carolina's 25/50/25 minimum applies to every vehicle on the policy, so adding a vehicle increases the liability premium proportionally unless the multi-car discount offsets it.
- The multi-car discount in South Carolina requires all vehicles on the same policy and typically the same garaging address; vehicles garaged at separate addresses may not qualify.
- Each vehicle's year, make, model, and assigned driver shape its individual cost, and the multi-car discount is applied after each vehicle's base rate is calculated.
- South Carolina's 10.3% uninsured motorist rate as of 2023 drives higher uninsured motorist premiums, calculated per vehicle on the multi-car policy.
- Carriers writing in South Carolina — including State Farm, Geico, Progressive, Allstate, and Farmers — structure the multi-car discount differently; comparing carriers shows which gives the largest discount for your specific vehicle and driver profile.
- Adding a third or fourth vehicle to a South Carolina multi-car policy increases the multi-car discount percentage but also adds the new vehicle's exposure, so the net cost change depends on the vehicle's profile and the assigned driver's history.

Multi-Car Policy Structure
A multi-car policy puts two or more owned vehicles on a single policy, each carrying its own coverage level — liability only or full coverage — while the entire policy earns the multi-car discount.
Liability-Only on One Vehicle
Liability-only coverage meets South Carolina's 25/50/25 minimum without collision or comprehensive. On a multi-car policy, one vehicle can carry liability-only while another carries full coverage, and both qualify for the multi-car discount.
Full Coverage Per Vehicle
Full coverage adds collision and comprehensive to the liability minimum. On a South Carolina multi-car policy, each vehicle can carry full coverage independently, and the multi-car discount applies to the entire policy regardless of which vehicles have physical damage coverage.
Uninsured Motorist Coverage
Uninsured motorist coverage is mandatory in South Carolina and protects each vehicle on your multi-car policy when an at-fault driver has no coverage. The premium is calculated per vehicle, so adding a vehicle increases the uninsured motorist cost.
Adding a Vehicle Mid-Term
Adding a vehicle to a South Carolina multi-car policy mid-term triggers a policy re-rate effective the date the vehicle is added. The new vehicle's premium is prorated for the remaining term, and the multi-car discount recalculates across all vehicles.
Combining Household Policies
Combining two separate policies into one multi-car policy after marriage or a household member moving in consolidates the multi-car discount, but only if both households share a garaging address and meet the carrier's same-policy requirements.
