Fault system (no-fault vs at-fault) in South Dakota

South Dakota handles car crashes under the at-fault (tort) system, not no-fault, and it uses an unusual slight-versus-gross negligence rule that can bar recovery below 50 percent fault. Here are the state's exact rules, numbers, and deadlines, each cited to the statute or agency behind it.

South Dakota is an at-fault state, also called a tort state. There's no no-fault law here, and drivers aren't required to carry personal injury protection (PIP). If another driver caused your crash, that driver, through their liability insurance, is responsible for your medical bills, lost income, and vehicle damage.12 You don't bill your own policy first the way people do in true no-fault states like Florida or Michigan.

That one difference shapes how much you can recover, how you prove your case, and how long you have to act. What follows is specific to South Dakota, with a citation to the statute or agency behind each rule.

How the at-fault system works here

After a crash you generally have three routes. You can file a third-party claim against the at-fault driver's liability insurer, file under your own coverages such as collision or uninsured motorist, or file a lawsuit. South Dakota's financial responsibility law, in Title 32, chapter 35, is built around liability coverage rather than a no-fault benefit pool.1 The state Division of Insurance confirms there's no PIP requirement, and medical payments coverage is sold only as an optional add-on.2

Because the at-fault driver pays, the real fight in most claims comes down to two questions: who caused the crash, and what share of the blame, if any, belongs to you.

The comparative fault rule that makes South Dakota unusual

Most states use a clean percentage rule. You recover as long as you were less than 50 or 51 percent at fault. South Dakota doesn't work that way. Under SDCL 20-9-2, your own contributory negligence bars your recovery unless it was "slight in comparison with the negligence of the defendant." If it was slight, you still recover, but your damages are cut in proportion to your share of the fault.3

"Slight" isn't a fixed number. It's a qualitative call the jury makes by comparing the two drivers' conduct, and it tends to cut against injured people. In Wood v. City of Crooks, the South Dakota Supreme Court held that a 30 percent share of fault is more than slight as a matter of law, which barred the plaintiff from recovering anything.4 In a state with an ordinary 50 percent rule, that same plaintiff would have collected 70 percent of the damages. In South Dakota, the recovery was zero.

So when an adjuster starts assigning you a slice of the blame, the stakes are higher here than almost anywhere else. Even a modest fault percentage can end the claim.

What drivers are required to carry

South Dakota's minimum liability limits are 25/50/25: $25,000 for bodily injury to one person, $50,000 for all bodily injuries in one accident, and $25,000 for property damage.1 Those are floors, and they run out quickly in a serious wreck.

Two coverages here are unusual because the state makes them mandatory. Every liability policy issued in South Dakota has to include uninsured motorist (UM) coverage and underinsured motorist (UIM) coverage, each at limits equal to your bodily injury coverage, up to $100,000 per person and $300,000 per accident unless you ask for more.56 UM pays when the driver who hit you had no insurance. UIM pays when their limits were too small to cover what you lost. One rule worth knowing: you can't add your UM and UIM limits together for the same accident.7

Medical payments coverage is available if you want it, but it isn't required, and there's no PIP at all.2

How long you have to file

The clock is shorter for your body than for your car. A personal injury claim has to be filed within three years of the crash under SDCL 15-2-14.8 A claim for damage to your vehicle gets six years, because vehicle property damage falls under the catch-all in SDCL 15-2-13.9 So a diminished value claim on your car has twice the runway of your injury claim.

If the injured person was a minor at the time of the crash, the three-year injury clock is paused until they turn 18 under SDCL 15-2-22, which generally leaves a child until around age 21 to bring a claim.10

Miss the deadline and the court will almost always dismiss the case, however strong it is. Pulling the official crash report from the South Dakota Department of Public Safety's Office of Accident Records early gives you the responding officer's account of fault while the deadlines are still open.11

There's no cap on what a South Dakota crash claim is worth

South Dakota does not cap the damages you can recover in an ordinary car accident. There's no ceiling on medical bills, lost income, or pain and suffering caused by a negligent driver. The only damage cap in the code, SDCL 21-3-11, is limited to medical malpractice claims against doctors, hospitals, and other health providers, and it does not reach car crash cases.12 Even that narrow cap survived only after the courts trimmed a broader one: in Knowles v. United States, the state Supreme Court struck down the old $1 million cap as unconstitutional.13

Punitive damages are possible but hard to reach. A jury can award them when a driver's conduct was willful, wanton, or malicious, which can fit a drunk or street-racing driver, under SDCL 21-3-2.14 Before you can pursue them or even take discovery on the issue, the judge has to hold a hearing and find, by clear and convincing evidence, a reasonable basis to believe the conduct met that standard (SDCL 21-1-4.1).15

If a drunk driver hit you

This is where South Dakota surprises people. The state has no dram shop liability. If a bar kept serving an obviously drunk patron who then crashed into you, you generally cannot sue the bar. The Legislature declared in SDCL 35-11-1 that drinking the alcohol, not serving it, is the legal cause of any resulting injury.16 Social hosts are shielded under SDCL 35-11-2,17 and licensed vendors are shielded under SDCL 35-4-78 even when they served someone who was obviously intoxicated.18

What you still have is a claim against the drunk driver personally, including the punitive damages described above.14 Evidence that the driver was breaking South Dakota's ban on using a mobile electronic device while driving (SDCL 32-26-47.1, a Class 2 misdemeanor that took effect in 2020 and covers texting, browsing, and watching video) or was otherwise impaired helps establish the negligence at the heart of the claim.19

Getting help with a South Dakota claim

The slight-versus-gross fault rule and the mandatory UM/UIM structure make South Dakota claims easy to underestimate on your own. If your injuries are more than minor, or an insurer is already pinning fault on you, talk to a local attorney before you give a recorded statement or accept an early offer. You can start with the legal directory to find one who handles South Dakota crash cases.
