Iowa 80 in Walcott is the world's biggest truck stop, which tells you how much traffic runs across I-80 here. If you were hit on that road, or on a two-lane in harvest season behind a grain truck, here's what you need to know about the clock in Iowa.
The truck accident statute of limitations in Iowa appears to be 2 years from the date of the crash (Iowa Code § 614.1(2)). Wrongful death generally runs 2 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: 2 years. The evidence clock is shorter than all of them.
How current these numbers are
A licensed attorney checked these Iowa 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 an Iowa lawyer before you rely on them.
What driving I-80 across the state is really like
Iowa's I-80 is long, flat and windy. Crosswinds blow empty trailers over, and ground blizzards in winter bring visibility to nothing on open stretches between Des Moines and Iowa City. Pileups involving dozens of vehicles happen almost every year. I-35 north toward Minnesota and I-29 along the Missouri River have the same wind problem. Off the interstates, harvest season brings grain trucks, combines and anhydrous tanks onto narrow county roads. Hog and cattle trailers make frequent stops and pull out slowly. Summer brings severe storms and sometimes tornadoes, and spring flooding on the Missouri and Mississippi has closed interstates for weeks.
I-80 through Iowa is a transcontinental truck artery, and the Iowa 80 truck stop at Walcott is the largest in the world. Grain, ethanol and hog production put heavy agricultural equipment on rural two-lanes for much of the year. Crashes pile up on I-80 across the state, I-35 (Des Moines–Minnesota), I-380 through the Cedar Rapids corridor, I-29 along the Missouri River and US-20 and US-30.
How the clock plays out: a crash on I-80
Say you're driving west on I-80 near Grinnell in a January ground blizzard. Traffic ahead stops, you stop, and a tractor-trailer behind you doesn't. Now you're one of 20 vehicles in a pileup, and every insurer is blaming the weather. The truck's ECM data will show how fast it was going in near-zero visibility. That data can be overwritten when the truck is repaired and back on the road. The weather is part of the story, not the whole story. Near the Walcott and Grinnell exits, truck-stop fuel receipts and scale tickets can also pin down where that driver had been and when.
What makes Iowa different
Iowa is one of the few states that does not spring a short notice trap on claimants — both the State and municipal tort claim periods run two years, matching the ordinary deadline. The risk in Iowa is therefore almost entirely on the evidence side: a through-hauler on I-80 may be domiciled 1,500 miles away and have no reason to keep anything past the federal minimum.
The four Iowa deadlines that matter
| Deadline | Period | Runs from | Citation |
|---|---|---|---|
| Personal injury lawsuit | 2 years | the date of the crash | Iowa Code § 614.1(2) |
| Wrongful death claim | 2 years | the date of death | Iowa Code § 614.1(2) |
| Notice — state entity | 2 years | the date of the crash | Iowa Code § 669.13 |
| Notice — city, county or district | 2 years | the date of the crash | Iowa Code § 670.5 |
If a government vehicle was involved in Iowa
Shortest government notice window found for Iowa: 2 years (Iowa Code § 669.13). Here it isn't shorter than the ordinary deadline, but it's still a precondition to suing, and missing it usually bars the claim entirely. Iowa Tort Claims Act claims are presented to the State Appeal Board within two years. Municipal tort claims also run two years, so Iowa avoids the very short notice traps common elsewhere.
Public fleets you could realistically be hit by here: Iowa DOT maintenance trucks, county secondary road department equipment, DART and other municipal transit vehicles, 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 Iowa under Iowa Code § 614.8. 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.
When the Iowa clock starts
Applies. Iowa runs the clock from when the plaintiff knew or should have known of the injury and its cause.

The evidence clock runs faster than 2 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 an Iowa claim
- Iowa State Patrol handles most interstate crashes. Request the Iowa crash report and note the trooper's name.
- In a multi-vehicle pileup, write down every truck's company name and USDOT number you can see. There may be several carriers involved.
- Iowa DOT's 511 system logs road conditions and closures. Note the time of the crash so those records can be matched.

Crashed near the Iowa 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 |
|---|---|---|
| Minnesota | 6 years | 3 years |
| Wisconsin | 3 years | 3 years |
| Illinois | 2 years | 2 years |
| Missouri | 5 years | 3 years |
| Nebraska | 4 years | 2 years |
| South Dakota | 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, the notice requirement (2 years) applies on top of the ordinary deadline.
- Don't give a recorded statement to the trucking company's insurer.
- Get the Iowa crash report; it names the carrier, DOT number and insurer.
- Have a lawyer licensed in Iowa confirm these dates against the current statute.
