## Quick answer

In South Dakota you generally have 3 years from the crash to sue for injuries, 6 years for vehicle damage and 3 years from the date of death for a wrongful death claim. South Dakota's fault rule is unusual: you can recover only if your own negligence was "slight" compared with the other driver's, and there is no fixed percentage, so the outcome depends on how a jury sees the facts. A claim against a city, county or the state needs a written notice within 180 days.

## Filing deadlines in South Dakota

South Dakota's statute of limitations gives injury claims and vehicle damage claims different deadlines: the vehicle claim lasts twice as long as the injury claim.

| Claim | Deadline | Law |
|---|---|---|
| Personal injury | 3 years | SDCL § 15-2-14(3) |
| Damage to your vehicle or other property | 6 years | SDCL § 15-2-13(4) |
| Wrongful death | 3 years from the date of death | SDCL § 21-5-3 |
| Claim against a public entity | Written notice within 180 days | SDCL 3-21-2 |

For an injured child, South Dakota uses a tolling rule: the time before a child reaches adulthood is not counted, but the extension cannot run longer than one year after that. A licensed attorney can confirm the last day to file for a particular child.

Before suing a public entity or its employee, you must give a notice of claim: written notice within 180 days of the injury, saying when, where and how it happened. The notice goes to the attorney general and the commissioner of human resources and administration for the state, or the county auditor for a county; SDCL 3-21-3 names the officials for cities and other public bodies. The notice does not extend the normal deadline to sue.

> **Warning:** Insurance negotiations do not pause any of these deadlines. If a claim is still open as a deadline gets close, a lawsuit may need to be filed to protect it.

## How fault is shared in South Dakota

South Dakota uses a "slight versus gross" comparison instead of a percentage bar. Under SDCL 20-9-2, your own carelessness does not bar recovery if it "was slight in comparison with the negligence of the defendant." If it was, your damages are reduced in proportion to your share. If it was more than slight, you recover nothing.

There is no percentage cut-off. The jury compares your conduct with the other driver's, and what counts as "slight" depends on the facts of each case. That makes South Dakota claims harder to predict than in states with a 50% or 51% bar.

> **Example:** You were driving a few miles over the limit when another driver ran a stop sign and hit you. If the jury decides your speeding was slight next to the other driver's negligence, you recover your damages, reduced by your share. If it decides your negligence was more than slight, you recover nothing, even though the other driver was more to blame.

The [fault-rule explainer](https://accidentclaimfacts.com/tools/fault-rule-explainer/?state=sd&fault=20#fault) shows why a 20% share can go either way in South Dakota, and how other states treat the same split.

## Insurance in South Dakota

South Dakota is an at-fault state: the driver who caused the crash, through their insurer, pays for the losses. Insurers must also offer optional first-party benefits; if you bought them, your own policy may pay some medical bills whoever was at fault.

| Coverage | Rule in South Dakota |
|---|---|
| Bodily injury liability | $25,000 per person, $50,000 per crash |
| Property damage liability | $25,000 |
| Uninsured motorist | Required: equal to your bodily injury limits (insurer need not exceed $100,000/$300,000 unless you ask) |
| Underinsured motorist | Required: equal to your bodily injury limits (same $100,000/$300,000 cap unless you ask for more) |
| Personal injury protection | Must be offered: supplemental first-party benefits (medical expenses, disability income, accidental death); optional to buy |
| Medical payments | Must be offered as part of supplemental coverage (at least $2,000 per person); optional |

Because uninsured motorist coverage is required, it often pays when the other driver had no insurance; see [uninsured driver accidents](https://accidentclaimfacts.com/accidents/uninsured-driver-accidents/). The Insurance Information Institute estimates that 9.4% of South Dakota drivers were uninsured in 2023, compared with 15.4% nationally. The South Dakota Division of Insurance (Department of Labor and Regulation) answers consumer questions at 605-773-3563.

## After a crash in South Dakota

Drivers must immediately notify the nearest law enforcement officer after a crash that causes injury, death or reportable property damage. Property damage is reportable at $1,000 or more to any one person's property, or $2,000 for the whole crash. If the driver cannot report, a passenger who is able to must do it.

The officer who investigates puts a notice on the damaged vehicle saying the crash has been reported, and must send the report to the Department of Public Safety within 3 days after finishing the investigation. South Dakota crash reports are not confidential. You can get a copy from the Department of Public Safety, which charges a search fee for each request ($4). Our [police report guide](https://accidentclaimfacts.com/claim-process/police-report/) explains what these reports contain and how to correct mistakes.

## Special rules in South Dakota

**Bars and stores that serve alcohol.** Many states have a dram shop law that lets crash victims sue a bar that over-served a drunk driver. South Dakota law takes the opposite view: drinking, not serving, is the legal cause of injuries an intoxicated person causes. The legislature passed this in 1985 to overturn a 1982 state Supreme Court decision. The drunk driver remains responsible; see [drunk driver crashes](https://accidentclaimfacts.com/accidents/drunk-driver-accidents/) for how those claims work.

**Seat belts.** In South Dakota, not wearing a seat belt is not negligence and cannot be used in a civil case on the injuries or on reducing damages. So in a South Dakota lawsuit, the other side generally cannot use a missing seat belt to cut your damages.

## Crashes on South Dakota roads

The Insurance Institute for Highway Safety counted 146 crash deaths in South Dakota in 2024, or 15.8 per 100,000 people, compared with 11.5 per 100,000 people nationally. Rural roads accounted for 80% of the deaths, and speeding played a part in 23%. An estimated 37% of the passenger vehicle drivers killed had a blood alcohol concentration of 0.08 g/dL or higher.

## FAQ

### What is the statute of limitations for a car accident in South Dakota?

Generally 3 years from the crash for injuries, 6 years for vehicle damage and 3 years from the date of death for wrongful death. A claim against a public entity also needs a written notice within 180 days of the injury.

### Is South Dakota a no-fault state?

No. South Dakota is an at-fault state. Insurers must offer optional first-party medical and disability benefits, but buying them does not limit your right to sue the driver who caused the crash.

### Can I recover if I was partly at fault in South Dakota?

Only if your negligence was slight compared with the other driver's. Then your damages are reduced by your share. If a jury finds your negligence more than slight, you recover nothing, and there is no fixed percentage that decides it.

### Can I sue a bar that served a drunk driver in South Dakota?

South Dakota law treats drinking, not serving, as the legal cause of the harm an intoxicated person causes, which generally rules out such claims against the seller. A licensed attorney can say whether any exception applies; the main claim is against the drunk driver and their insurance.

### Will not wearing a seat belt hurt my claim in South Dakota?

Generally no. South Dakota law says not wearing a seat belt is not negligence and cannot be raised in a civil case on the injuries or on reducing damages.
