Personal Injury Laws in Idaho: Deadlines, Fault Rules & Damages

Idaho's Personal Injury Statute of Limitations: 2 Years

In Idaho, you generally have two (2) years from the date of the injury to file a lawsuit for a personal injury caused by someone else's negligence. This deadline comes from Idaho Code § 5-219(4), which covers actions "to recover damages for professional malpractice, or for an injury to the person, or for the death of one caused by the wrongful act or neglect of another." Miss this window and, with narrow exceptions, an Idaho court will dismiss your case no matter how strong it is.

Two exceptions matter most for ordinary people:

• Minors: Idaho law tolls (pauses) the clock for injured children, though the tolling period is capped, so the two-year clock does not necessarily start the day a child turns 18. Confirm the current tolling rule with the statute or an Idaho attorney if the injured person was under 18.
• Discovery rule: In some cases — most notably medical malpractice — the clock can start when the injury was, or reasonably should have been, discovered rather than the date of the underlying act.

Because statutes of limitations are strictly enforced and get amended from time to time, always confirm the current text of Idaho Code § 5-219 on the Idaho State Legislature's official website before assuming your deadline.

Idaho's Shared-Fault Rule: Modified Comparative Negligence (50% Bar)

Idaho is a modified comparative negligence state under Idaho Code § 6-801. In practice this works out to a "50% bar":

• If you were 49% or less at fault, you can still recover damages, but your award is reduced by your percentage of fault. For example, if a jury finds you were 20% at fault and your damages total $100,000, you would recover $80,000.
• If you were 50% or more at fault, Idaho law bars you from recovering anything.

The statute itself says contributory negligence does not bar recovery so long as it "was not as great as" the negligence of the person you're suing, and that damages are "diminished in proportion" to your own share of fault. Fault percentages are typically decided by a jury (or a judge in a bench trial) based on the evidence, so insurance adjusters' informal fault assessments are not the final word. Read the current statute on the Idaho Legislature's site.

Damage Caps in Idaho

Non-economic damages

Idaho caps non-economic damages (pain and suffering, disfigurement, loss of consortium, and similar losses) in personal injury and wrongful death cases — not just medical malpractice — under Idaho Code § 6-1603. The base cap was set at $250,000 in the 1980s, but the statute requires it to be adjusted every July 1 based on changes in Idaho's average annual wage, as calculated by the Idaho Industrial Commission. As of the most recent adjustment (effective July 1, 2025), the published cap was approximately $509,013, but this number changes annually — confirm the current figure directly with the Idaho Industrial Commission or the current statutory text before relying on it.

Important exceptions: the cap does not apply where the harm resulted from willful or reckless misconduct, or from conduct a jury finds beyond a reasonable doubt to be a felony. The Idaho Supreme Court upheld the constitutionality of this cap against a jury-trial-rights challenge in Kirkland v. Blaine County Medical Center (2000), so — unlike in some states — Idaho's non-economic cap has not been struck down and remains in force.

Economic damages

Idaho does not cap economic damages — your documented medical bills, lost wages, and future lost earning capacity are recoverable in full, subject to proof.

Punitive damages

Punitive damages are capped separately under Idaho Code § 6-1604 at the greater of $250,000 or three times the compensatory damages awarded. Punitive damages also require "clear and convincing evidence" of oppressive, fraudulent, malicious, or outrageous conduct, and a claim for them generally must be added to a lawsuit by motion after the case is already filed — Idaho does not allow a punitive-damages claim in the initial complaint.

Idaho's Car Insurance System: At-Fault (Tort), Not No-Fault

Idaho is an at-fault (tort) insurance state — it is not a no-fault or Personal Injury Protection (PIP) state. That means:

• The driver who caused the crash (and their insurer) is financially responsible for the other driver's injuries and property damage.
• An injured person can file a claim directly against the at-fault driver's liability insurance, or sue the at-fault driver, rather than being required to first exhaust their own PIP coverage.
• Idaho's minimum required liability limits are commonly summarized as 25/50/15: $25,000 bodily injury per person, $50,000 bodily injury per accident, and $15,000 property damage per accident.

Minimum limits change periodically, so verify current requirements with the Idaho Department of Insurance before assuming these figures are current. Because Idaho's minimum limits are low relative to serious injury costs, many injured Idahoans end up looking to their own underinsured/uninsured motorist coverage as well.

Idaho's Dog-Bite Rule: Strict Liability

Idaho imposes strict liability on dog owners (and anyone who has accepted responsibility as the dog's possessor, harborer, or custodian) for bites and other injuries, under Idaho Code § 25-2810. This means an injured person generally does not have to prove the owner knew the dog was dangerous — often called the "one bite" requirement in other states. Idaho's law applies civil liability when the injured person was not trespassing and did not physically provoke the dog. Recognized defenses include the victim's trespassing, provocation, and certain working/service-animal situations. Because this statute has been amended over time, confirm the current text on the Idaho Legislature's website.

Suing the Government in Idaho: A Much Shorter Deadline

If your injury involves a city, county, school district, highway district, or the State of Idaho itself — a pothole-related crash, a slip and fall at a public building, an injury caused by a government vehicle or employee — the ordinary two-year statute of limitations does not give you the full runway. Under the Idaho Tort Claims Act, Idaho Code § 6-905, you must present a written notice of claim to the proper government office within 180 days of the date the claim arose (or reasonably should have been discovered). This notice requirement is treated as jurisdictional — courts have dismissed cases where injured people missed it, even though their two-year deadline for filing suit had not yet run. If the government denies the claim, or does not act within 90 days, the claimant can then proceed to file a lawsuit, subject to the standard limitations period. Read the notice requirements directly on the Idaho Legislature's Tort Claims Act chapter and confirm the correct office to file with, since it differs for state versus local claims.

Where to File: Idaho State Courts

Most personal injury lawsuits in Idaho are filed in the district court for the county where the injury occurred or where the defendant resides; smaller claims may be eligible for magistrate court or small claims court depending on the amount at issue. You can find court locations and self-help resources through the Idaho Courts website.

What to Do in Idaho

1. Get medical care and document everything. Medical records are your primary proof of both the injury and its cost, and gaps in treatment can be used to argue you weren't really hurt.
2. Identify whether a government entity might be involved. If a city, county, school, or state vehicle/property is involved, treat the 180-day notice deadline as your real deadline — don't wait for the two-year clock.
3. Preserve evidence early. Photos of the scene, witness names and contact information, and any surveillance or dashcam footage can disappear quickly.
4. Report the incident. File a police report for a crash, or an incident report with the property owner/business for a fall or dog bite.
5. Track your losses. Keep pay stubs showing missed work, medical bills, mileage to appointments, and receipts for anything you had to buy because of the injury.
6. Understand your own fault exposure. Because Idaho bars recovery at 50% fault or more, be careful about statements (to insurers, police, or on social media) that could be used to inflate your share of blame.
7. Check your own auto policy. Since Idaho is a fault-based state with relatively low minimum limits, look at your own underinsured/uninsured motorist and medical payments coverage.
8. Confirm current deadlines and figures before acting. Statutes of limitations, notice periods, and damage caps are all subject to change or annual adjustment — verify the current numbers against the official Idaho Code before you rely on them, especially as a deadline approaches.
