Minimum Coverage Requirements in South Carolina
South Carolina operates under a tort liability system and requires SR-22 filing after DUI conviction — FR-44 does not apply here. The South Carolina Department of Motor Vehicles mandates ignition interlock device installation for all DUI offenses, including first-time convictions, before any restricted license is issued. Proof of SR-22 insurance must be on file with SCDMV before you can schedule IID installation or hardship license issuance.

South Carolina SR-22 insurance after DUI costs significantly more than standard coverage due to mandatory high-risk classification. The SR-22 filing fee itself is $25–$50, but the premium increase from DUI conviction raises total annual cost by 80–140% depending on your age, county, and prior history.
What Affects Your Rate
- First-offense DUI in South Carolina increases premiums an average of 85% for the 3-year SR-22 period — second offense raises rates by 125–150%.
- Greenville and Spartanburg County drivers pay 12–18% more than state average due to higher accident frequency on I-85 corridor.
- Drivers under age 25 with DUI SR-22 pay $340–$480 monthly on average — older drivers age 35–55 average $180–$260 monthly for the same coverage.
- Adding ignition interlock device endorsement to your SR-22 policy typically adds $10–$25 monthly, though some carriers include it at no additional premium cost.
- Non-owner SR-22 policies cost 60–70% less than standard SR-22 — monthly premiums range $30–$80 depending on age and violation history.
- Switching carriers mid-filing period triggers a new SR-22 filing fee and potential coverage gap — South Carolina SCDMV receives lapse notice within 10 days if the old policy cancels before the new SR-22 is filed.

Route Restricted License
South Carolina's hardship license for DUI offenders, called a Route Restricted License, allows driving only to work, school, medical appointments, DUI program, and IID service appointments. You submit approved locations and times to SCDMV — deviation from these routes is a criminal violation.
Ignition Interlock Requirement
South Carolina mandates IID installation for all DUI offenses — first offense requires 6 months, second offense 2 years, third offense 3 years. Device prevents vehicle start if breath sample detects alcohol above .02 BAC.
SR-22 Filing Requirement
SR-22 is a certificate of financial responsibility your insurance carrier files with SCDMV proving continuous coverage. South Carolina requires 3-year SR-22 filing after DUI conviction. Any lapse triggers immediate license suspension.
Non-Owner SR-22 Insurance
Non-owner SR-22 provides liability coverage when you drive a vehicle you do not own and satisfies South Carolina's SR-22 requirement. Required if you sold your vehicle, lost it to impound, or never owned one but need a Route Restricted License.
High-Risk Auto Insurance
High-risk carriers specialize in SR-22 policies for drivers with DUI convictions, suspended licenses, or multiple violations. These carriers often approve coverage faster and with fewer restrictions than standard carriers.
DUI Program Completion Insurance
South Carolina requires completion of ADSAP (Alcohol and Drug Safety Action Program) before full license reinstatement. Your SR-22 insurance must remain active throughout ADSAP enrollment — premiums may decrease slightly after program completion but SR-22 filing continues for the full 3 years.
