Rule or statute summary

Run this scenario in DocketMath using the Statute Of Limitations calculator.

In Wisconsin, the time limit to sue for many car-accident-related injuries is often governed by the state’s general statute of limitations for personal injury, which is commonly described as a 6-year default period under Wis. Stat. § 939.74(1).

DocketMath’s statute-of-limitations calculator uses this general/default period of 6 years as its baseline for Wisconsin car-accident timing. No claim-type-specific sub-rule was found for this brief, so the guidance below focuses on the default rule (not separate timelines for different categories of claims).

What this means in practical terms

Use this 6-year baseline to estimate a deadline to file a lawsuit based on the limitations “start” date for your particular facts. In practice, the “start” date can depend on accrual details (for example, which date your claim is considered to have started for limitations purposes).

DocketMath helps you:

  • enter a start date (the best-supported “start” date for your situation)
  • get an estimated latest filing date
  • run scenarios to see how different start dates change the deadline

Note: These are time-based rules. Missing a deadline can bar a claim even if the underlying facts are compelling. Accrual and tolling doctrines can also affect results and aren’t fully captured by a basic date calculator.

Wisconsin general/default limitations period

  • General period: 6 years
  • Statute: Wis. Stat. § 939.74(1) (general/default period)

Because this brief is focused on a general/default car-accident SOL estimate, the timeline below is anchored to the 6-year general period and does not add claim-type-specific sub-rules.

How the DocketMath calculator aligns with the statute

DocketMath’s statute-of-limitations calculator takes the duration (here, 6 years) and applies it to your chosen input start date to generate an estimated end date.

Checklist to use it effectively:

Inputs to enter

Typical workflow:

  1. Jurisdiction: Wisconsin (US-WI)
  2. Statute basis: General/default 6-year period
    • **Wis. Stat. § 939.74(1)
  3. Start date: the date you’re using as the limitations “start” for the estimate

Output you’ll see

With a 6-year duration, DocketMath will calculate the estimated deadline by adding 6 years to your chosen start date.

Example (illustrative)

  • Start date: January 10, 2024
  • Period: 6 years (Wis. Stat. § 939.74(1))
  • Estimated deadline: January 10, 2030 (exact output may vary depending on how the tool handles dates)

How changing inputs changes the result

  • If you move the start date forward by 30 days, the estimated deadline typically moves forward by about 30 days.
  • If you run multiple scenarios (for example, different candidate “start” dates), the scenario with the later start date will typically produce the later estimated deadline.

Warning: A calculator output is an estimate, not a final legal determination. Wisconsin deadlines can involve additional complexities like accrual timing and tolling, depending on the circumstances.
