Every August, I-90 across South Dakota fills with motorcycles heading to Sturgis, and the trucks don't stop running. Mix in the Black Hills tourist traffic and the long empty stretches west of the Missouri, and you get a road with very different kinds of danger.
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.
How current these numbers are
A licensed attorney checked these South Dakota figures against the cited statutes on 2026-09-20. Statutes still change (Florida cut its injury period in half in 2023; Louisiana doubled its own in 2024), so confirm with a South Dakota lawyer before you rely on them.
Life next to big rigs on I-90
I-90 runs the width of the state from Sioux Falls to Rapid City, flat for most of it and hilly near the Black Hills. It's long and lonely, and fatigue is a real problem. Winter brings blizzards and ground blizzards that close the interstate for days. Wind across the prairie can push trailers off the road. I-29 carries freight north from Sioux Falls toward Fargo. In fall, harvest brings grain trucks onto every road, and pheasant season adds hunters in pickups pulling off onto shoulders. The Black Hills roads are twisty and steep, with tourists who stop without warning.
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. Crashes pile up on 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.
How the clock plays out: a crash on I-90
Say you're riding to Sturgis on I-90 and a tractor-trailer changes lanes into you near Wall. You're thrown, badly hurt, and flown to Rapid City. You live out of state, and once you're home, you're a thousand miles away from where it happened. The trucking company has local people who can collect evidence right now. You have to make sure someone is doing the same for you.
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.
Every South Dakota clock in one table
| 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 |
If a government vehicle was involved in South Dakota
Shortest government notice window found for South Dakota: 180 days (SDCL § 3-21-2). It comes due long before the ordinary deadline, it's a precondition to suing, and missing it usually bars the claim entirely. 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 here: SDDOT plow and maintenance trucks, county highway department equipment, municipal fleets in Sioux Falls and Rapid City, and school district buses. Not sure the vehicle was one of these? Work to the shorter deadline until someone confirms otherwise.
If the injured person was a minor
Tolled to age 18 in South Dakota under SDCL § 15-2-22. The clock generally doesn't start until the injured person turns 18. That pause covers the court deadline, not the evidence: a carrier may destroy a driver's logs six months after the crash no matter the injured person's age, and in many states a government notice deadline isn't tolled for a child either.

The evidence clock runs faster than 3 years
- 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 runs; often lost on repair or resale.
- Driver logs: six months (49 CFR § 395.8(k)(1)).
- Maintenance 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)).
Until a written preservation letter reaches the carrier, destroying records at the end of a retention period is routine and lawful. The FMCSA regulations and evidence guide explains each record.
Local moves that protect a South Dakota claim
- The South Dakota Highway Patrol handles most interstate crashes. Ask for the report number and trooper's name.
- During the Sturgis rally, law enforcement and businesses along I-90 may have extra cameras. Ask quickly before footage is cleared.
- If a blizzard or wind was involved, save any SDDOT closure notices or weather warnings from that day.
Crashed near the South Dakota line?
A crash a few miles over a border can fall under a different deadline. If you're not sure which state you were in, 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 |

Next steps
- Get a preservation letter to the carrier. It's the most time-critical step.
- Confirm whether a government entity was involved. If so, your 3 years deadline may give way to 180 days.
- Don't give a recorded statement to the trucking company's insurer.
- Get the South Dakota crash report; it names the carrier, DOT number and insurer.
- Have a lawyer licensed in South Dakota confirm these dates against the current statute.
