South Dakota is one of the few states that requires both uninsured and underinsured motorist coverage on auto policies. The Division of Insurance says uninsured motorist coverage is required on all policies, and state law says underinsured coverage must be issued at a face amount equal to your bodily injury limits, up to a cap of $100,000 per person unless you ask for more. Liability limits are 25/50/25.
That structure changes how a crash with an underinsured driver plays out. If the other driver has 25/50 limits and your own UIM limits are higher, your coverage can pick up where theirs ends, but South Dakota's UM and UIM coverages are not stackable, so you cannot add the other driver's payment on top of your limit. Penalties are criminal rather than purely administrative: failing to maintain financial responsibility is a Class 2 misdemeanor, and a conviction brings a license suspension and a three-year SR-22 filing.
| Minimum liability | 25/50/25 (BI per person / BI per accident / PD, in $1,000s) |
|---|---|
| Other required coverage | Uninsured motorist (UM) coverage on all policies; Underinsured motorist (UIM) coverage equal to the policy's bodily injury limits, up to $100,000 per person (SDCL 58-11-9) |
| Fault system | At-fault (tort) |
| Credit-based insurance scores | Allowed |
| SR-22 / proof of financial responsibility | The Department of Public Safety says a conviction for lacking financial responsibility requires filing proof of insurance (an SR-22) for three years from the date of conviction. |
South Dakota minimum liability limits
To register and drive a car in South Dakota you need at least this much liability coverage:
- $25,000 for injuries to one person in an accident you cause.
- $50,000 in total for injuries to everyone in that accident.
- $25,000 for damage to other people's property, such as their car.
Tip: The minimum is a legal floor, not a recommendation. If a serious crash costs more than your limits, you could be personally responsible for the rest. See how much liability coverage you may need.

Is South Dakota a no-fault state?
South Dakota is an at-fault (tort) state. The driver who causes a crash is responsible for the other people's injuries and property damage, which is normally paid by that driver's liability insurance. Injured people can claim against the at-fault driver's insurer or, in some cases, sue.
South Dakota is an at-fault state. It uses a modified comparative negligence rule that weighs your fault against the other driver's, so your own share of blame can reduce or bar a claim.

Tips for South Dakota drivers
- Read the UIM limit on your declarations page. Because South Dakota ties it to your bodily injury limits, raising your liability limits also raises your underinsured protection up to the statutory cap.
- Remember that UM and UIM coverages in South Dakota are not stackable. The Division of Insurance explains that you cannot add the at-fault driver's liability payment to your UIM coverage to exceed your stated limit.
- UM coverage pays for injuries to you, your resident family members and passengers in your vehicle, but not damage to your car. Ask about collision or comprehensive if you want vehicle damage covered.
- If your license is suspended for a financial responsibility violation, expect to need an SR-22 for three years. Keeping continuous coverage during that period matters.
- South Dakota allows written proof of financial responsibility to be presented to the magistrate on a citation. Keep your insurance card or policy proof current so you can answer a citation promptly.
When you shop, compare quotes from several insurers using the same limits and deductibles, so the prices are like-for-like.
