The truck accident statute of limitations in Wisconsin appears to be 3 years from the date of the crash (Wis. Stat. § 893.54(1m)(a)). 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: 120 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 Wisconsin 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.

3. Did anyone die in the crash?

A wrongful death claim runs on a separate clock, and in most states it is measured differently.

4. Was a government vehicle or entity involved?

A city or county truck, a state DOT vehicle, a transit bus, a school district bus, a USPS vehicle, or a claim about how the road itself was built or maintained.

5. Was the injured person under 18 at the time?

In most states the clock is paused for a child — but the evidence clock is not, and in many states a government notice deadline is not either.

What makes Wisconsin different

Wisconsin's 120-day government notice is short relative to its three-year deadline, and it applies both to state officers and employees under § 893.82 and to local governmental subdivisions under § 893.80. Tolling for a minor is capped at two years past their 18th birthday rather than granting a fresh full period.

Claims against a government entity in Wisconsin

The shortest government notice window found for Wisconsin 120 days (Wis. Stat. § 893.82). 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 within 120 days for a claim against a state officer, employee or agent. Notice of the circumstances of the claim to the governmental subdivision within 120 days.

Public fleets you could realistically be hit by in Wisconsin: WisDOT maintenance trucks, county highway department equipment, MCTS buses in Milwaukee, municipal fleets, 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, capped at 2 years past majority in Wisconsin under Wis. Stat. § 893.16 — 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 Wisconsin clock starts

Applies. Wisconsin runs the clock from discovery of the injury and its cause, subject to statutory limits.

Why the evidence clock in Wisconsin is much shorter

Wisconsin'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 Wisconsin

Wisconsin moves dairy, paper, and heavy manufacturing freight, and I-94 between Milwaukee and the Twin Cities is a primary Upper Midwest corridor. Frac sand operations in the western counties add heavy short-haul truck traffic on rural roads.

The corridors where these crashes concentrate: I-94 (Milwaukee–Madison–Eau Claire), I-43 and I-41 up the lakeshore, I-39/US-51 through central Wisconsin, I-90 toward Minnesota and US-8 and US-53 in the north.

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.

What to do next in Wisconsin

  1. Get a preservation letter to the carrier. This is the most time-critical step and the one almost nobody hears about.
  2. Confirm whether a government entity was involved. That answer can replace your 3 years deadline with a far shorter notice window — 120 days.
  3. Do not give a recorded statement to the trucking company's insurer.
  4. Request the Wisconsin crash report, which identifies the carrier, the DOT number and the insurer.
  5. Have a lawyer licensed in Wisconsin confirm the dates above against the current statute.
