Car Accident Statute of Limitations in Idaho

Idaho gives you two years from the date of a crash to file a personal injury lawsuit. That deadline comes straight from Idaho Code 5-219(4)¹, and it's shorter than the three-year window several neighboring states use. Miss it, and the court will almost certainly throw the case out no matter how strong the underlying claim is.

When the two-year clock actually starts

Idaho ties the deadline to when the crash happened, not to when you realized how bad the injury was. The statute accrues "as of the time of the occurrence, act or omission complained of," full stop.¹ A driver who feels fine at the scene and develops disc herniation symptoms eight months later doesn't get extra time; the clock started on impact.

There are two narrow exceptions written into the same statute: a surgical object left inside a patient, and injury that was fraudulently concealed by the person who caused it.¹ Neither applies to a typical rear-end or intersection crash, so plan around the two-year date on the calendar, not around when treatment ends.

Wrongful death claims run on the same two years

If a crash kills someone, the surviving family's wrongful death claim is still governed by the two-year period in Idaho Code 5-219(4), measured from the date of death rather than the date of the crash.¹ The right to bring that claim itself comes from Idaho Code 5-311, which lets heirs, personal representatives, and a defined list of dependents (spouses, children, parents, and certain other relatives) recover on the decedent's behalf.²

Children hurt in a crash get more time, but not automatically until 18

Idaho Code 5-230 tolls the statute of limitations while an injured person is a minor.³ Plenty of articles describe this as "the clock doesn't start until the child turns 18," and that's often true, but the statute caps the tolling at six years regardless of age.

That cap matters more than most parents realize. A teenager hurt at 15 gets the benefit of tolling all the way to 18, then two more years to file, until age 20. A toddler hurt at age 3, though, hits the six-year tolling ceiling at age 9, and the two-year clock starts running then, not at 18.³ Work backward from the crash date, not forward from a birthday, to find the real deadline for a child's claim.

Property damage has its own three-year window

A claim for damage to the vehicle itself, separate from any injury claim, runs under Idaho Code 5-218(3), which gives three years from the date of the damage for actions involving injury to goods or chattels.⁴ That's a full year longer than the personal injury deadline, and it's the statute that governs a stand-alone diminished value claim if the crash wasn't your fault.

Idaho's 50 percent fault bar shapes how fast insurers move

Idaho follows a modified comparative negligence rule under Idaho Code 6-801: a driver can recover damages reduced by their share of fault, but only if that share is less than the other side's.⁵ Cross the 50 percent line and there's no recovery at all. Because so much turns on how fault gets allocated, insurers and defense attorneys often slow-walk settlement talks right up against the filing deadline, betting that a claimant without a lawyer will let the case lapse rather than sue. Filing suit, or at least retaining counsel, well before the two-year mark keeps that leverage on the claimant's side.

What's actually recoverable if you do sue

Idaho places no cap on economic damages such as medical bills, lost income, or future care costs. Noneconomic damages, meaning pain and suffering, are capped, but the number moves every year: the Idaho Industrial Commission recalculates it each July 1 based on the change in the state's average annual wage, as required by Idaho Code 6-1603.⁶ The commission's own published table puts the cap at $538,425.04 for the period beginning July 1, 2026, up from $509,013.28 the year before.⁷

Punitive damages are rarer and capped separately: the greater of $250,000 or three times compensatory damages, and only on clear and convincing evidence of oppressive, fraudulent, malicious, or outrageous conduct under Idaho Code 6-1604.⁸ A claimant can't plead punitive damages in the original complaint either; Idaho requires a separate pretrial motion showing a reasonable likelihood of proving it before the claim can even be added.⁸

Minimum insurance won't cover a serious crash

Idaho drivers only have to carry 25/50/15 liability coverage: $25,000 per person and $50,000 per accident for bodily injury, $15,000 for property damage, under Idaho Code 49-117(20).⁹ Those limits get exhausted fast in a crash with real injuries, which is why uninsured and underinsured motorist coverage matters here. Idaho Code 41-2502 requires insurers to include UM/UIM bodily injury coverage on every policy they issue, though the named insured can reject either or both in writing.¹⁰ If someone rejected that coverage years ago without realizing it, there may be nothing behind the at-fault driver's minimum limits to collect from.

Idaho doesn't require personal injury protection or medical payments coverage either. MedPay is sold only as an optional add-on, with no state-mandated deadline for using it, so check the policy itself rather than assume a statutory rule applies.¹¹

Drunk driving crashes carry their own notice deadline

If a bar or server contributed to a drunk driving crash, Idaho's dram shop law is narrow: a claim only reaches the establishment if the intoxicated person was underage or was obviously intoxicated when served, and the injured party must send certified-mail notice within 180 days of when the claim arose, separate from the underlying two-year suit deadline.¹² Punitive damages against the drunk driver still require the same clear-and-convincing standard as any other punitive claim.⁸

Motorcycle helmets and phone use

Idaho's helmet law only reaches riders and passengers under 18; adult riders can legally go without one, which sometimes becomes a fault argument insurers raise anyway.¹³ Handheld phone use while driving has been illegal under Idaho Code 49-1401A since July 1, 2020, with fines starting at $75 for a first offense and climbing to $300 by a third within three years, plus a possible 90-day license suspension after three convictions.¹⁴ A cited driver's phone records can become central evidence in a comparative-fault fight, another reason not to let a claim sit.

Winter crashes and getting your report

Idaho's mountain passes and valley fog make it a genuine snow state for a good chunk of the two-year clock. Idaho State Police logged nearly 17,000 crashes and 137 deaths statewide between October 2023 and April 2024 alone.¹⁵ Whatever the season, a claim needs the official report to move forward; find out how to get an Idaho crash report once you're ready to request it.

Don't wait to talk to someone

Two years sounds like a long time until medical treatment, insurance back-and-forth, and simple procrastination eat into it. If fault is contested, a minor is involved, or a drunk driver was behind the wheel, the deadlines start stacking in ways that are easy to miscalculate alone. An Idaho attorney can pin down the actual filing date and deal with the insurer during treatment; find one through the legal directory.
