Minimum Coverage Requirements in South Dakota
South Dakota mandates minimum liability coverage of 25/50/25: $25,000 bodily injury per person, $50,000 per accident, and $25,000 property damage. Drivers with DUI convictions, license suspensions for points, uninsured accidents, or repeat violations typically must file SR-22 proof of financial responsibility with the South Dakota Department of Public Safety for 3 years. High-risk drivers often need higher limits than state minimums because one at-fault accident can exceed $25,000 in property damage, leaving the driver personally liable for the difference.
How Much Does Car Insurance Cost in South Dakota?
High-risk drivers in South Dakota pay 40–200% more than standard rates depending on violation type, with DUI offenders seeing the steepest surcharges. A clean-record driver paying $85/mo for minimum coverage can expect $180–$250/mo after a DUI, while drivers needing full coverage with SR-22 often pay $300–$500/mo. Rates begin decreasing 3–5 years after the violation drops from your record, assuming no new incidents.

- Years since violation: rates drop 10–20% annually after year three if no new incidents occur
- SR-22 filing status: active SR-22 requirement typically adds $50–$120/mo beyond the violation surcharge
