South Dakota's minimum liability limits are 25/50/25, $25,000 of bodily injury coverage per person, $50,000 per accident, and $25,000 for property damage, but that's only part of the mandate. Unlike most at-fault states, South Dakota also requires every auto policy to carry both uninsured motorist and underinsured motorist coverage, each at limits no lower than $25,000/$50,000. You can't waive them.
The result is that a legal-minimum South Dakota policy protects you in more scenarios than a legal-minimum policy in, say, Georgia or Tennessee: if the other driver has no insurance or too little of it, your own policy responds. Carriers price that bundle very differently from one another, which is exactly where comparing quotes earns its keep.
The figures below explain the policy structure used in South Dakota. They do not predict an individual premium. For a broader view of how state rules differ, use our national car insurance directory.
South Dakota minimum car insurance requirements
Most quotes begin with liability coverage. Bodily injury liability addresses covered injury claims made by other people when you cause a crash. Property damage liability addresses covered damage to their vehicles or other property. The legal minimum keeps a policy compliant, but it does not say how much financial risk a household can comfortably retain.

What the state minimum covers, and what it leaves with you
A minimum policy is designed to satisfy state law. It is not designed around the value of your car, the size of a possible injury claim or the amount of savings you want to protect. Those are household decisions, so they need a separate review.
A financed or leased vehicle commonly needs collision and comprehensive coverage under the contract even when state law does not require them. For plain-language definitions and buying context, visit our insurance guides before selecting limits.
Rules and risks that matter in South Dakota
State law is only the starting point. These South Dakota-specific details show what to confirm before you compare coverage or buy a policy.
Why UM and UIM are built into every South Dakota policy
SDCL §58-11-9 requires uninsured motorist coverage on every motor vehicle policy issued in the state, and §58-11-9.4 adds underinsured motorist coverage, both at least at the $25,000/$50,000 bodily-injury minimums. UM pays when the at-fault driver has no insurance or is a hit-and-run; UIM steps in when their limits are too low for your injuries.
Nationally, 15.4% of drivers were uninsured in 2023, per the Insurance Research Council, so a mandate that most states leave optional does real work here. It also means you can't strip a South Dakota quote down to bare liability to chase a lower number: every quote you compare already includes UM and UIM, making the comparison more apples-to-apples than in most states.
Driving uninsured and SR-22s in South Dakota
Driving without insurance in South Dakota is a Class 2 misdemeanor under SDCL §32-35-113, punishable by a fine, up to 30 days in jail, and license suspension. After a conviction, a DUI, or certain other violations, the state requires an SR-22 filing: a certificate your insurer files proving you carry the required coverage, typically for multiple years.
The filing fee itself is small. The real cost is how carriers surcharge the underlying violation, and those surcharges vary widely from one insurer to the next, which makes SR-22 drivers the group with the most to gain from comparing several quotes rather than renewing on autopilot.
What South Dakota drivers pay
South Dakota consistently ranks among the lower-cost states for auto insurance: NAIC data puts the state's average annual expenditure at $823 in 2022, well under the $1,127 countrywide figure. Rural traffic density helps, though hail and wind exposure pushes comprehensive premiums higher than the liability side would suggest. Individual quotes still spread widely around that average depending on driving record, vehicle, and ZIP code, the average tells you about the market, not about your price.

Average annual expenditure for auto insurance in South Dakota was $823 in 2022. This is a historical statewide expenditure benchmark from NAIC 2022 Auto Insurance Database Average Premium Supplement (June 2024). It combines many types of drivers and policies, so it should be used for market context rather than as a current quote estimate.
Insurers apply their filed rating plans to the household in front of them. Two neighbors can see different prices, and the same household can receive a wide range from different companies because each insurer weighs the inputs differently.
Garaging location
Claim frequency, traffic, repair costs, theft and weather exposure vary across South Dakota ZIP codes.
Drivers and record
Age, driving experience, citations, accidents, claims and continuous insurance history can affect price and eligibility.
Vehicle and use
Repair technology, vehicle value, annual mileage, commute and business use change the potential cost of a claim.
Coverage choices
Liability limits, collision, comprehensive, optional benefits and deductibles determine what the policy is being asked to pay.
Household details
Other licensed drivers, additional vehicles and bundling opportunities can change the account-level price.
Company fit
Insurers target different customer profiles. No one company is consistently cheapest for every driver in every territory.
