What to do after a car accident in South Dakota

You've just been in a crash somewhere in South Dakota, maybe on I-90 outside Rapid City or a side street in Sioux Falls. The immediate steps are the same anywhere: check for injuries, get to safety, call for help, and trade information with the other driver. Our national hub covers that general playbook. This page is about what's specific to South Dakota, the exact rules and numbers that change how your claim works here.

What the law requires at the scene

South Dakota makes reporting a serious crash mandatory. Under SDCL 32-34-7, if anyone is hurt or killed, or the wreck causes property damage of $1,000 or more to one person's property or $2,000 or more in total, you have to give immediate notice to the nearest available law enforcement officer by the quickest means you can. Failing to do so is a Class 2 misdemeanor.¹

Get the officer's name and the report number before you leave the scene. When you need a copy of the official crash report later, our South Dakota crash report page walks through how to get one.

South Dakota pays for crashes on a fault basis

South Dakota is an at-fault, or tort, state. It doesn't use a no-fault system, and there's no PIP requirement here. The state Division of Insurance lists Medical Payments (MedPay) coverage as optional, something you can buy but aren't required to carry.² So the driver who caused the crash, through their liability insurer, is the one responsible for your injuries and vehicle damage. If you did buy MedPay, it can pay your medical bills up front no matter who was at fault.

The required insurance is thinner than most people expect

Every driver has to carry at least 25/50/25 in liability coverage: $25,000 for bodily injury to one person, $50,000 per accident, and $25,000 for property damage (SDCL 32-35-70).³ A single ambulance ride and ER visit can pass $25,000, so a minimum policy often won't cover a serious injury.

South Dakota builds in a backstop for that. Uninsured motorist (UM) coverage is required on every auto liability policy at limits equal to your own bodily injury coverage (SDCL 58-11-9), and underinsured motorist (UIM) coverage is required the same way (SDCL 58-11-9.4).⁴⁵ Both are capped at $100,000 per person and $300,000 per accident unless you ask for higher limits, which is usually worth doing. You can't stack your UM and UIM limits on top of each other for a single accident (SDCL 58-11-9.7).⁶ If the driver who hit you carried no insurance or too little, this coverage is what pays you.

You usually have three years, with a few exceptions

The deadline to file a personal injury lawsuit in South Dakota is three years from the date of the crash (SDCL 15-2-14(3)).⁷ Miss it and the court will almost certainly dismiss the case, however strong it is.

Two wrinkles matter. Property damage runs on a longer clock: a claim for the damage to your vehicle falls under the state's six-year limit for injury to goods and chattels (SDCL 15-2-13(4)), twice as long as the injury deadline.⁸ And for a child hurt in a crash, the rule is stricter than most people assume. The clock is paused while the injured person is under 18, but SDCL 15-2-22 caps that pause, so the suit still has to be filed within one year after the child turns 18, not a fresh three years.⁹ If your teenager was injured, don't sit on it.

If your car is worth less on paper even after a solid repair, that loss is a separate claim. Our South Dakota diminished value page explains how that one works.

How fault gets divided here is unusual

Most states use a straight percentage bar that cuts you off at 50% or 51% fault. South Dakota doesn't. It uses its own slight-gross rule (SDCL 20-9-2): you can recover only if your own negligence was "slight" in comparison with the other driver's, and your award is then reduced in proportion to your share of fault.¹⁰ "Slight" isn't a fixed number; it's a judgment call left to the jury. South Dakota courts have treated a plaintiff who was 30% at fault as more than slightly negligent as a matter of law, which means you can lose your claim entirely at a fault level that wouldn't bar recovery in a standard comparative-fault state. Building the fault story carefully from day one matters more here than in most places.

What you can recover, and what South Dakota won't allow

There is no statutory cap on compensatory damages in an ordinary car accident case. South Dakota's best-known damages cap, the $1 million ceiling on medical malpractice awards in former SDCL 21-3-11, was struck down as unconstitutional in Knowles v. United States, 1996 SD 10, 544 N.W.2d 183.¹¹ Your economic losses, like medical bills and lost income, and your non-economic losses, like pain and loss of enjoyment of life, aren't limited by a figure set in advance.

Punitive damages are possible but hard to reach. They're authorized only where the at-fault driver acted with oppression, fraud, or malice, or by willful and wanton misconduct (SDCL 21-3-2), and before that claim can go to a jury, the judge has to hold a hearing and find, by clear and convincing evidence, a reasonable basis to believe such conduct happened (SDCL 21-1-4.1).¹²¹³

There's also no dram shop liability in South Dakota. If a drunk driver hits you, you generally can't sue the bar that kept serving them. State law treats drinking the alcohol, not serving it, as the legal cause of the harm (SDCL 35-11-1), shields social hosts from liability (SDCL 35-11-2), and protects licensed sellers from civil suits even when the sale itself broke the law (SDCL 35-4-78).¹⁴¹⁵¹⁶ Your claim runs against the driver, and drunk driving is exactly the kind of conduct that can support punitive damages against that person.

Distracted driving, helmets, and winter roads

Since 2020, SDCL 32-26-47.1 has barred using a mobile electronic device to text, take or send photos, watch video, or browse the internet while driving. It's a Class 2 misdemeanor, and an officer can pull you over for it alone.¹⁷ Proof that the other driver was on a device can be a large part of establishing fault.

Motorcyclists have a partial helmet law. Riders and passengers under 18 must wear a DOT-standard helmet (SDCL 32-20-4); adults may legally ride without one, which comes up when an insurer tries to pin a rider's head injuries on going without.¹⁸ Lane splitting is illegal for everyone, so a motorcycle weaving between lanes of stopped or moving traffic is breaking the law (SDCL 32-20-9.3).¹⁹

Winter is its own hazard on South Dakota roads. The state gets heavy snow and ice, and the Department of Transportation runs a Winter Weather Hub and the SD511 system for current road conditions.²⁰ A driver who loses control on a stretch known to be icy is still expected to have driven for the conditions, so "the road was slick" rarely works as a defense.

When to bring in a lawyer

You don't need an attorney for every dented bumper. But the slight-gross fault rule and low policy limits can combine with a firm three-year deadline in ways that quietly cost you money, especially when injuries are serious or the other side disputes fault. If that's your situation, you can find a South Dakota attorney through our legal directory. Most personal injury lawyers will review a car accident claim for free.
