Suffering an injury due to someone else’s negligence turns your life upside down—and the legal questions that follow can feel overwhelming. From understanding how Idaho determines fault and what deadlines apply to knowing what compensation you may be entitled to and how the claims process works, there is a lot to learn before moving forward. This guide answers the most frequently asked questions about personal injury cases in Boise and across Idaho, breaking down state laws, fault rules, settlement timelines, and what you can expect at every stage. Whether you were hurt in a car crash, a slip-and-fall, or another incident, this information will help you make informed decisions and protect your legal rights.
Idaho is a fault-based (tort) state. Unlike Utah, which requires Personal Injury Protection (PIP) coverage, Idaho has no mandatory PIP or no-fault insurance system. When you are injured in an Idaho accident, you make a claim against the at-fault party's liability insurance. Not through your own insurer. Your medical bills and lost wages are not automatically covered by your own policy. You must establish the other party's fault to recover.
Idaho Code § 41-2502 requires drivers to carry minimum liability coverage. It is $25,000 per person / $50,000 per accident for bodily injury. For property damage, it is $15,000. Optional coverages include MedPay (medical payments) through your own policy, which pays medical bills regardless of fault; and UM/UIM (uninsured/underinsured motorist) coverage for when the at-fault driver is uninsured or underinsured. Given Idaho's roads and the frequency of serious accidents on I-84 and US-20, carrying UM/UIM is strongly advisable.
Idaho has a significant uninsured-driver problem. If the at-fault driver is uninsured, your recovery depends on your own UM (uninsured motorist) coverage—available under your policy if you elected it. If the at-fault driver is insured but their limits are insufficient to cover your damages, your UIM (underinsured motorist) coverage pays the gap up to your policy limits. Without UM/UIM coverage, recovery from an uninsured at-fault driver requires suing them personally, which is often uncollectible.
Two years from the date of injury under Idaho Code § 5-219. This is strict. Missing the deadline bars your claim entirely, regardless of how strong it is. If you were injured in a Boise accident and the two-year period is approaching, contact an attorney immediately—the filing process takes time even after you hire representation.
The Idaho Tort Claims Act (§ 6-905) gives you only 180 days to file a written notice of claim with the government entity. This applies to the following: City of Boise vehicles, Ada County Sheriff vehicles, Idaho State Police vehicles, ACHD (Ada County Highway District) road conditions, Boise State University transportation, and all other state and local government entities. The notice must be in writing, identify you and the incident, describe the damages, and identify the government entity. Missing this 180-day window permanently bars recovery from the government entity — even if the 2-year SOL hasn't run. A personal injury attorney should submit the notice of claim as soon as possible after any government-involved accident.
Idaho's modified comparative fault rule (§ 6-801) allows you to recover as long as you are less than 50% at fault. Your award is reduced by your fault percentage. A 20% fault attribution on a $200,000 case costs you $40,000. But if you are found exactly 50% at fault—the same as the defendant—you recover nothing. This makes early, aggressive fault attribution critical in Idaho cases. Insurance adjusters know the 50% rule and will push claimant fault toward that threshold to minimize payouts.
Fault is determined through the police report, crash reconstruction, witness statements, traffic and surveillance camera footage, physical evidence at the scene, medical records documenting the mechanism of injury, and expert analysis. If the case goes to trial in the Fourth Judicial District Court, the jury decides fault. Insurance adjusters conduct their own investigations, which are not independent. A Boise personal injury attorney conducts an independent investigation to counter inflated fault assignments.
Fourth Judicial District Court, Ada County Courthouse, 200 W Front Street, Boise, ID 83702. This court handles all civil matters for Ada County — the county containing Boise, Meridian, Eagle, Star, Kuna, and Garden City. The filing fee for a personal injury complaint is approximately $221 (per the Idaho civil action fee schedule). After filing, the defendant has 21 days to respond to the complaint under the Idaho Rules of Civil Procedure.
Pre-lawsuit settlements (after reaching maximum medical improvement) typically resolve 6–18 months after the accident. Cases requiring a lawsuit in the Fourth Judicial District Court typically take 18–30 months from filing to resolution, depending on the docket load and complexity. Cases with disputed liability, government defendants, or commercial vehicles (FMCSA-regulated trucking) run longer due to discovery complexity. Idaho's courts are less congested than some metro districts, but complex cases still require time.
