Drivers in South Dakota pay an average of $2,060 per year ($172/month) for full-coverage car insurance in 2026 — about 14% below the national average of $2,392. That makes South Dakota the #15 cheapest of the 51 U.S. jurisdictions we track. A state-minimum policy averages $420 per year, versus a $895 national average.
Averages hide a wide spread: your own quote depends on your ZIP code, driving record, age, and vehicle — and the gap between the cheapest and most expensive carrier for the same South Dakota driver is routinely over $1,000 a year. The only way to know where you land is to check your own rate.

Minimum car insurance requirements in South Dakota
South Dakota requires drivers to carry at least 25/50/25 liability coverage, plus UM/UIM. Here's what those numbers mean:
| Coverage | Required minimum | What it pays for |
|---|---|---|
| Bodily injury (per person) | $25,000 | Injuries you cause to one person in an accident |
| Bodily injury (per accident) | $50,000 | Total injuries you cause in one accident |
| Property damage | $25,000 | Damage you cause to vehicles and property |
| Also required | UM/UIM | Additional coverage South Dakota mandates on every policy |
Note: UM/UIM of 25/50 is also required; second-cheapest minimum coverage in the country.
Keep in mind that state minimums are the legal floor, not a recommendation — a serious accident can exceed $50,000 in injuries quickly, leaving you personally liable for the rest. Most South Dakota drivers are better served comparing the cost of higher limits, which is often smaller than expected.

How South Dakota drivers pay less
- Compare at every renewal. Carrier pricing in South Dakota shifts constantly; the insurer that was cheapest for you two years ago frequently isn't today.
- Bundle home or renters insurance — multi-policy discounts commonly run 10–25%.
- Raise your deductible if you have savings to cover it; going from $500 to $1,000 typically cuts the collision/comprehensive portion 10–20%.
- Ask about usage-based programs if you drive less than ~10,000 miles a year — low-mileage pricing is one of the fastest-growing discounts in 2026.
- Special situations have their own playbook: see our guides for teen drivers, coverage after a DUI, and getting insured after a lapse.
