The truck accident statute of limitations in South Dakota appears to be 3 years from the date of the crash (SDCL § 15-2-14(3)). Wrongful death generally runs 3 years from the date of death. If a government vehicle or entity was involved, formal written notice is generally required first, on its own clock: 180 days. The evidence clock is shorter than all of them.
Before you rely on these numbers
The statutory figures on this page have not yet been verified against current statute text by a licensed attorney. They are published with their citations so they can be checked, and they should be treated as a starting point for a conversation with a South Dakota lawyer — not as a legal conclusion. Statutes change: Florida cut its personal injury period in half in 2023 and Louisiana doubled its own in 2024.
Your deadlines in South Dakota, calculated
Enter the date of your crash and the tool below will work out both clocks — the legal filing deadline and the much shorter window before the proof can be destroyed. South Dakota is already selected. Nothing you type is sent anywhere.
What makes South Dakota different
South Dakota's 180-day notice to a public entity goes to the chief executive officer of that entity — or the Attorney General for a State claim — and the state's rural road network means a county highway department is a plausible defendant in a crash on a gravel or two-lane route. South Dakota also applies discovery accrual narrowly, so the clock generally starts on the day of the crash.
The four South Dakota deadlines that matter
| Deadline | Period | Runs from | Citation |
|---|---|---|---|
| Personal injury lawsuit | 3 years | the date of the crash | SDCL § 15-2-14(3) |
| Wrongful death claim | 3 years | the date of death | SDCL § 21-5-3 |
| Notice — state entity | 180 days | the date of the crash | SDCL § 3-21-2 |
| Notice — city, county or district | 180 days | the date of the crash | SDCL § 3-21-2 |
Claims against a government entity in South Dakota
The shortest government notice window found for South Dakota — 180 days (SDCL § 3-21-2). This is the deadline that quietly ends claims: it comes due long before the ordinary filing deadline, it is a precondition to suing rather than a suggestion, and missing it usually bars the claim entirely no matter how strong the case is.
Written notice to the Attorney General for a State claim within 180 days. Notice to the chief executive officer of the public entity within 180 days.
Public fleets you could realistically be hit by in South Dakota: SDDOT plow and maintenance trucks, county highway department equipment, municipal fleets in Sioux Falls and Rapid City, and school district buses. If you are not certain whether the vehicle that hit you was one of these, work to the shorter deadline until somebody confirms otherwise. The downside is not symmetrical.
If the injured person was a minor
Tolled to age 18 in South Dakota under SDCL § 15-2-22 — the clock generally does not start until the injured person turns 18.
That pause applies to the court deadline. It does not apply to the evidence. A carrier is entitled to destroy a driver's logs six months after the crash whether the injured person is 8 or 38, and in many states a government notice deadline is not tolled for a child either. A tolled filing deadline and an untouched evidence deadline is the most dangerous combination on this page.
When the South Dakota clock starts
Limited. South Dakota applies discovery accrual narrowly.
Why the evidence clock in South Dakota is much shorter
South Dakota's filing deadline is 3 years. The federal retention rules that govern the trucking company are measured in weeks and months:
- Dashcam and telematics video — often 30 days or less. No federal retention requirement — vendor and carrier policy only.
- ECM / black box data — overwritten as the tractor keeps running, and routinely lost when it is repaired or resold.
- Driver logs and records of duty status — six months (49 CFR § 395.8(k)(1)).
- Maintenance and repair records — one year while the vehicle is in the carrier's control (49 CFR § 396.3(c)).
- Annual inspection report — 14 months (49 CFR § 396.21(b)(1)).
The way to stop those clocks is a preservation letter to the carrier — a written demand that specific evidence be kept. Until it arrives, destroying records at the end of a retention period is routine and lawful. Our FMCSA regulations and evidence guide explains what each of these records contains.
Truck traffic in South Dakota
South Dakota's freight is agricultural and livestock haulage plus I-90 through-traffic, with long distances between service points. Winter closures on I-90 west of the Missouri River are routine and can strand equipment for days.
The corridors where these crashes concentrate: I-90 (Sioux Falls–Rapid City–Wyoming), I-29 (Sioux Falls–North Dakota), US-83 and US-281, US-14 and US-212 and SD-79 through the Black Hills.
Neighbouring states have different clocks
A crash a few miles across a state line can be governed by a completely different deadline. If you are not certain which state your crash happened in — near a border, on a bridge, or on an interstate you were travelling at speed — check both.
| State | Injury deadline | Wrongful death |
|---|---|---|
| North Dakota | 6 years | 2 years |
| Minnesota | 6 years | 3 years |
| Iowa | 2 years | 2 years |
| Nebraska | 4 years | 2 years |
| Wyoming | 4 years | 2 years |
| Montana | 3 years | 3 years |

What to do next in South Dakota
- Get a preservation letter to the carrier. This is the most time-critical step and the one almost nobody hears about.
- Confirm whether a government entity was involved. That answer can replace your 3 years deadline with a far shorter notice window — 180 days.
- Do not give a recorded statement to the trucking company's insurer.
- Request the South Dakota crash report, which identifies the carrier, the DOT number and the insurer.
- Have a lawyer licensed in South Dakota confirm the dates above against the current statute.
