Multi-Car Liability Requirements in South Carolina
South Carolina requires every vehicle on a multi-car policy to carry minimum liability of $25,000 bodily injury per person, $50,000 bodily injury per accident, and $25,000 property damage. The state also mandates uninsured motorist coverage on every vehicle. South Carolina operates under a fault-based system, meaning the at-fault driver's liability coverage pays for damages. The multi-car discount applies when all vehicles sit on the same policy and typically requires a shared garaging address.

Multi-car premiums in South Carolina depend on the number of vehicles, the drivers assigned to each vehicle, the coverage level selected per vehicle, and the multi-car discount. South Carolina's average annual expenditure per insured vehicle was $1,539.47 in 2023, and combining vehicles on one policy reduces the per-vehicle cost through the multi-car discount. The vehicles themselves—year, make, model, safety features—drive the base rate before the discount applies.
What Affects Your Rate
- South Carolina's 25/50/25 liability minimum is the floor each vehicle on a multi-car policy must carry, and selecting higher limits increases the premium per vehicle.
- The multi-car discount applies when all vehicles sit on one policy and typically requires a shared garaging address; carriers writing in South Carolina structure the discount this way.
- Each vehicle's year, make, model, and safety features drive the base rate before the multi-car discount applies, so insuring a newer vehicle with advanced safety features costs more than an older vehicle with liability only.
- South Carolina's 10.3% uninsured motorist rate as of 2023 affects uninsured motorist coverage premiums, which are required on every vehicle on a multi-car policy.
- Adding a vehicle mid-term re-rates the entire policy rather than adding a flat amount, so the multi-car discount adjusts immediately to reflect the new vehicle count.
- Assigning drivers to specific vehicles on a multi-car policy affects cost; a teen driver assigned to one vehicle raises that vehicle's premium more than assigning an experienced driver.

Multi-Car Policy Structure
A multi-car policy covers two or more vehicles on one policy, each carrying its own coverage level, while the entire policy earns the multi-car discount. Each vehicle can carry liability only or full coverage.
Liability Insurance Per Vehicle
Liability insurance pays for injuries and property damage you cause to others in an at-fault accident. South Carolina requires 25/50/25 liability on every vehicle, including all vehicles on a multi-car policy.
Uninsured Motorist Coverage
Uninsured motorist coverage protects you when an at-fault driver has no insurance. South Carolina mandates this coverage on every vehicle, including all vehicles on a multi-car policy.
Full Coverage Per Vehicle
Full coverage adds collision and comprehensive to the liability minimum, paying for damage to your own vehicle. On a multi-car policy, each vehicle can carry its own coverage level—one vehicle might carry liability only while another carries full coverage.
Adding a Vehicle Mid-Term
Adding a vehicle to an existing multi-car policy mid-term re-rates the entire policy rather than adding a flat amount. The new vehicle must carry at least the state liability minimum, and the multi-car discount adjusts immediately.
Combining Household Policies
Combining two separate policies into one multi-car policy after marriage or a household member moving in requires a shared garaging address and re-rates all vehicles under the multi-car discount.
