If you were hurt in Idaho by someone else's conduct, you generally have two years from the date of the injury to file a personal-injury lawsuit. The deadline comes from Idaho Code 5-219, and the clock starts on the date the harm occurred. Miss the window and the courthouse door closes, even if the underlying case is strong.
The two-year number is the rule most Idaho injury searches return. The biggest trap is the Idaho Tort Claims Act 180-day Notice of Tort Claim that applies to any claim against the State or a political subdivision. Miss the 180 days and the case ends regardless of the two-year SOL. This post walks through what the two-year SOL really means in 2026, where the exceptions are, and the fact patterns we see trip people up most.
The default Idaho PI window: two years under Idaho Code 5-219
Idaho Code 5-219(4) sets a two-year statute of limitations for actions to recover damages for professional malpractice, personal injury, or death. It is the catch-all for the vast majority of Idaho PI cases: car crashes, slip-and-falls, dog bites, premises liability, and most negligence claims.
The clock starts on the date of the wrongful act. Idaho recognizes a narrow discovery rule for some categories -- but Idaho's discovery rule is more restrictive than many states. The Idaho Supreme Court has held that the cause of action accrues when there is "some damage," even if the full extent is not yet known.
Idaho is a fault-based auto-insurance state. The injured party's recovery generally runs through the at-fault driver's insurer or your own uninsured-motorist coverage.
Exception one: the Idaho Tort Claims Act 180-day Notice
The Idaho Tort Claims Act (ITCA, Idaho Code chapter 6, sections 6-901 et seq.) governs claims against state and local government. ITCA requires a Notice of Tort Claim within 180 days after the claim arose or reasonably should have been discovered.
- State of Idaho: Idaho Code 6-905 -- 180 days, filed with the Secretary of State.
- Political subdivisions (counties, cities, school districts, highway districts): Idaho Code 6-906 -- 180 days, filed with the clerk of the political subdivision.
The notice must contain a concise statement of the claim, the facts, the amount of damages claimed, and the claimant's residence. Idaho courts treat the 180-day notice as a jurisdictional prerequisite. Idaho Code 6-908 sets a separate two-year SOL for ITCA claims that runs in parallel with the 180-day notice.
The ITCA also caps damages -- the cap is periodically adjusted; verify the current cap before relying on it.
The single most common Idaho PI trap: a claimant injured on a county road or by a state vehicle assumes the two-year SOL applies, contacts an attorney seven or eight months after the incident, and learns the 180-day ITCA notice has already run.
Exception two: medical malpractice
Medical-malpractice cases run under Idaho Code 5-219(4) with a two-year SOL from the date the negligent act occurred. Idaho's discovery rule for medmal is narrow -- the SOL runs from the act, not from discovery in most cases, with a foreign-object exception that allows one year from discovery.
Idaho also requires a pre-litigation screening panel review under Idaho Code 6-1001 et seq. for most medmal claims before suit can be filed.
Exception three: minors
Idaho Code 5-230 tolls the SOL during minority for general PI claims with a six-year cap -- the SOL runs from the date the minor reaches majority but in no event longer than six years from the date of accrual for most categories. The toll does NOT extend the ITCA 180-day notice.
What Idaho's modified 50% comparative-fault rule means
Idaho follows a modified comparative-fault rule with a 50% bar under Idaho Code 6-801. A plaintiff less than 50% at fault recovers, reduced by the percentage of plaintiff fault. A plaintiff 50% or more at fault recovers nothing.
That 50% threshold is where Idaho defense lawyers focus. Pushing fault from 49% to 50% ends the case.
A common Idaho fact pattern that ends cases early
A driver is struck by a Highway District vehicle on a rural Idaho road. The driver is treated and released, calls the District for damages, gets a "we'll review it," and assumes the case is being processed. Six months later, no resolution; the driver retains an attorney; the attorney discovers no ITCA notice was filed with the political subdivision within 180 days. The case is dismissed.
The takeaway: if any Idaho government entity is potentially involved (state, county, city, highway district, school district), treat the 180-day ITCA notice as the operative first deadline, not the two-year general SOL.
Other Idaho-specific PI rules worth knowing
Dog bites. Idaho does not have a strict-liability dog-bite statute; common-law negligence and the one-bite rule apply, with two-year SOL.
Wrongful death. Two-year SOL under Idaho Code 5-219. Standing under Idaho Code 5-311.
Premises liability. Two-year SOL. Modified 50% comparative-fault applies.
UM/UIM contract claims. Idaho treats UM/UIM claims as contract claims with a longer SOL -- generally five years under Idaho Code 5-216 for written contracts. Policies often impose shorter contractual deadlines.
How the LawSensai Personal Injury Recovery Center helps with Idaho matters
We built the Recovery Center to handle the day-one organizational work in an Idaho PI case so that nothing falls through the cracks during the two-year window. We document the incident through a calm, save-and-resume intake, build a medical-and-evidence timeline, and surface every applicable deadline, including the ITCA 180-day notice, the medmal pre-litigation screening panel step, and the underlying Idaho Code 5-219 two-year window. When the matter is well-documented and ready, we route it to a verified personal-injury attorney licensed in Idaho. Start your Idaho intake here.
We are not a law firm and we do not give legal advice. We are the file-organization and deadline-surfacing layer that sits in front of a real attorney.
