Idaho Car Accident Laws

Idaho's deadline and fault rule are fairly standard, but its damage cap on pain-and-suffering awards is a genuine outlier — and it's not a fixed number, since it moves with inflation annually.

Idaho's non-economic damage cap isn't a round number set once and forgotten — it climbs every year, so what applied to a 2022 case is different from what applies now.

Statute of limitations: 2 years (3 for property damage)

Under Idaho Code §5-219(4), you generally have two years from the date of the accident to file a personal injury lawsuit. Property damage claims get a longer, three-year window (§5-218.3). Claims against a government entity require notice within 180 days.

Fault rule: modified comparative negligence, 50% bar

Under Idaho Code §6-801, you can recover damages if you're found less than 50% at fault, reduced by your percentage. At 50% or more, you recover nothing.

Insurance and Idaho's inflation-adjusted damage cap

Idaho is an at-fault state. Minimum liability limits are 25/50/15: $25,000 per person and $50,000 per accident for bodily injury, plus $15,000 for property damage. Distinctively, Idaho caps non-economic damages (pain and suffering) under Idaho Code §6-1603, with a base of $250,000 that adjusts annually for inflation — it stood at roughly $490,512 as of mid-2024.

How this plays out in a real claim

Take an intersection collision where fault is genuinely disputed. If an insurer or court assigns you 40% of the blame, Idaho's rule still lets you recover 60% of your damages. But if that assessment creeps to 50% or above, the claim is barred entirely under Idaho's rule — not reduced, eliminated. That single threshold is exactly why insurers have a real incentive to push a borderline case just over the line rather than simply discount what they pay.

A mistake worth avoiding in Idaho

Because a single percentage point at the 50% threshold can be the entire difference between a reduced payout and nothing at all, careless statements at the scene or to an adjuster carry more weight here than in a pure comparative state. Avoid speculating about fault, even casually, until the full picture — police report, witnesses, any available footage — is in front of you.

If a government vehicle or agency was involved

The Idaho Tort Claims Act requires written notice within 180 days of the injury (or its discovery), filed with the clerk of the specific government subdivision involved, followed by a further two years to actually file suit (Idaho Code §§6-905 to 6-911). The government then has 90 days to respond to the notice. Punitive damages aren't available against a government entity in Idaho, and recovering from the entity itself generally forecloses a separate claim against the individual employee for the same incident.

If the crash resulted in a death

Idaho gives two years from the date of death for a wrongful death claim (Idaho Code §5-219), which either the heirs directly or the estate's personal representative may bring (§5-311). Idaho is unusually restrictive on one specific point: pain-and-suffering damages aren't recoverable in a wrongful death claim at all, whether for the decedent's suffering before death or the family's grief afterward — only economic losses and loss of society/companionship/comfort are available, and economic damages carry no cap.

Beyond the deadline and the fault rule

The statute of limitations and the fault rule above decide whether you have a claim and how much of it survives — they don't decide what the claim is actually worth, or whether it's worth handling yourself. For that, see our guides on what affects a settlement, who pays your medical bills while a claim is pending, and whether Idaho law makes a lawyer worth it for your specific situation.
