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, multiple at-fault accidents, uninsured driving citations, or license suspensions typically must file SR-22 proof of financial responsibility with the South Dakota Department of Public Safety. The state also requires uninsured/underinsured motorist coverage at the same 25/50 limits unless explicitly rejected in writing.
How Much Does Car Insurance Cost in South Dakota?
High-risk insurance premiums in South Dakota vary dramatically based on violation type, timing since the incident, and carrier appetite. A first DUI typically increases rates 80–150% over a clean record, while a second DUI or major at-fault accident can triple premiums or push you into the non-standard market entirely. South Dakota's relatively low population density and fewer carrier options in rural counties can limit competition and keep rates elevated compared to urban markets.
What Affects Your Rate
- Violation type: DUI typically costs 80–150% more than standard rates; multiple DUIs or felony charges can triple premiums
- Time since incident: rates typically decrease 15–25% at each policy renewal if no new violations occur during SR-22 period
- Age and location: drivers under 25 with violations in Sioux Falls or Rapid City face higher rates due to density and claims frequency
- Carrier type: non-standard specialists may charge 30–50% more than standard carriers willing to file SR-22
- Credit score: South Dakota allows credit-based insurance scoring, and poor credit combined with violations can increase rates an additional 40–70%
- Coverage gaps: any lapse in coverage during the past 3 years signals increased risk and raises premiums 20–40% at most carriers
