State Requirements
South Carolina operates under a tort-based liability system, meaning at-fault drivers are financially responsible for damages they cause. The state requires all drivers to carry proof of insurance and mandates electronic verification through the South Carolina Department of Motor Vehicles Insurance Verification System (IVS). Driving without insurance carries a $200 fine, license suspension, and a mandatory $550 uninsured motorist fee to reinstate registration, per the South Carolina Department of Insurance.
Cost Overview
South Carolina's average auto insurance rates run 8–12% below the national median, driven by lower population density outside the Charleston-Columbia-Greenville corridor. Coastal counties pay 15–25% more due to hurricane risk and higher traffic density, while Upstate and Pee Dee regions see the state's lowest premiums. Credit-based insurance scoring heavily influences rates in South Carolina — drivers with poor credit pay 60–90% more than those with excellent credit for identical coverage.
What Affects Your Rate
- Credit score impact: South Carolina allows credit-based insurance scoring, with poor credit adding $60–$110/month compared to excellent credit for the same coverage.
- Age and experience: Drivers under 25 pay 70–120% more than those aged 35–55, while seniors over 70 see rates increase 15–30% due to accident frequency data.
- Urban vs rural: Charleston and Columbia drivers pay 20–35% more than those in Spartanburg or Florence due to higher collision and theft claim rates.
- DUI or major violations: A DUI conviction increases premiums 80–150% for three to five years and may require SR-22 filing, which adds a $15–$50 fee.
- Annual mileage: Driving over 15,000 miles per year adds 10–20% to premiums, while low-mileage discounts (under 7,500 miles annually) can reduce rates by 5–12%.
- Vehicle age and value: Cars over 10 years old with market value under $3,000 typically make collision and comprehensive coverage cost-ineffective, saving $40–$70/month when dropped.

Liability Insurance
Covers injury and property damage you cause to others. South Carolina's 25/50/25 minimum is the legal floor, but one serious accident can exceed these limits by $50,000 or more, leaving you personally liable for the difference.
Uninsured Motorist Coverage
Pays your medical bills and vehicle damage when the at-fault driver has no insurance or flees the scene. You can reject this in writing to save money, but you'll have no coverage if hit by an uninsured driver.
Full Coverage
Bundles liability, collision, and comprehensive coverage. Mandatory if you finance or lease, but optional once you own the vehicle outright — especially when vehicle value drops below $4,000–$5,000.
SR-22 Insurance
Not a coverage type — it's a state filing proving you carry minimum liability insurance after a DUI, at-fault accident without insurance, or license suspension. Required for three years in South Carolina.
