Wisconsin Personal Injury Laws

In Wisconsin, you generally have 3 years from the date of injury to file a personal injury lawsuit. Missing this deadline almost always results in permanent loss of your right to sue, regardless of how strong your case is. Certain exceptions may apply — such as for minors, cases involving government entities, or injuries not immediately discovered. Claims against government entities in Wisconsin may have much shorter notice requirements. Consult a licensed Wisconsin attorney immediately if you believe your deadline may be approaching.

Wisconsin follows the Modified Comparative (51%) system. Under the modified comparative fault rule with a 51% bar, you can recover compensation as long as you were 50% or less at fault. Your recovery is reduced by your fault percentage. If you are 51% or more at fault, you cannot recover anything.

Wisconsin requires drivers to carry minimum bodily injury liability insurance of 25/50 (per person/per accident). These minimums are typically insufficient for serious injury cases. Uninsured/Underinsured Motorist (UM/UIM) coverage is also available in Wisconsin and is strongly recommended to protect yourself when the at-fault driver lacks adequate coverage.

After a car accident in Wisconsin, the injured party typically files a claim with the at-fault driver's bodily injury liability insurer. Wisconsin's fault system means liability must be established before compensation is paid. Strong documentation — police reports, medical records, photos, and witness statements — is essential. If the insurer disputes liability or offers an inadequate settlement, litigation in Wisconsin courts may be necessary.

Commercial truck accident cases in Wisconsin involve both state law and federal FMCSA regulations. Carriers operating in interstate commerce must comply with federal hours-of-service rules, vehicle maintenance standards, and driver qualification requirements. Violations of these regulations can be powerful evidence of negligence. Evidence preservation is critical — black box data, ELD records, and carrier documents must be secured immediately after a truck accident in Wisconsin.
