Minimum Coverage Requirements in South Carolina
South Carolina operates under a tort liability system, meaning the at-fault driver's insurance pays for damages. The South Carolina Department of Motor Vehicles requires continuous proof of insurance for all registered vehicles. After a DUI conviction, the state mandates SR-22 filing—a certificate proving you carry the minimum required coverage—for three years from the conviction date.
How Much Does Car Insurance Cost in South Carolina?
South Carolina SR-22 rates depend on the severity of your violation, your age, and how long ago the conviction occurred. Carriers classify DUI as a major violation, triggering rate increases that persist for three to five years. Multi-violation drivers—DUI plus reckless driving or license suspension—face the highest premiums.
What Affects Your Rate
- DUI conviction date—rates drop 15–25% after three years with no additional violations, once the SR-22 period ends and the conviction ages off carrier underwriting models.
- Blood alcohol content at arrest—BAC above 0.15% (South Carolina's enhanced penalty threshold) increases premiums 20–40% over standard DUI rates.
- Prior violations—a DUI combined with reckless driving, hit-and-run, or prior suspension moves you into assigned risk pools where rates can exceed $500/mo.
- Vehicle value—comprehensive and collision premiums increase directly with vehicle replacement cost; a financed $35,000 SUV costs $80–$120/mo more to insure than an older sedan.
- Zip code—Charleston and Columbia drivers pay 10–18% more than rural counties due to higher theft rates, accident frequency, and uninsured motorist claims.
- Carrier appetite—carriers like Progressive and The General specialize in high-risk drivers and often quote 20–35% lower than standard carriers who surcharge DUI violations heavily.

SR-22 Insurance
A certificate your carrier files with the South Carolina DMV proving you maintain the state-required minimum coverage. The SR-22 itself costs $25–$50 to file, but your underlying auto insurance premium increases significantly due to the DUI classification.
Non-Owner SR-22
Liability-only policy for drivers who do not own a vehicle but need SR-22 filing to reinstate their license. Covers you when driving borrowed or rental vehicles. Does not cover a vehicle you own or regularly use.
Full Coverage
Liability, collision, and comprehensive bundled together. Collision pays for damage to your vehicle in an at-fault accident; comprehensive covers theft, vandalism, weather, and animal strikes. Required by lenders and lessors.
Uninsured Motorist Coverage
Pays your medical bills and vehicle damage when the at-fault driver has no insurance or insufficient coverage. Includes underinsured motorist protection, which covers the gap when the other driver's limits are too low.
High-Risk Auto Insurance
Policies written by carriers specializing in drivers with DUI convictions, multiple violations, or lapses. Higher premiums than standard market, but often the only option for drivers standard carriers refuse to write.
