Idaho Truck Accident Lawyer Guide: Laws, Deadlines and Rights

Idaho's freight moves along I-84 through the Treasure Valley and Magic Valley, I-15 through Pocatello and Idaho Falls, I-86, I-90 through the Panhandle and US-95 across steep canyon grades and mountain passes. Winter weather, wind, long distances and narrow two-lane highways make a crash with a commercial truck especially dangerous. The Idaho Transportation Department (ITD) reported at least 277 traffic deaths in 2023, the deadliest year in two decades, and has described seat belt non-use, lane departures, speeding, impairment and inattention as recurring factors in fatal crashes. This guide explains the laws that matter most after a truck crash in Idaho, the evidence to protect and how to choose an Idaho truck accident lawyer. We do not recommend or rank any individual firm.

Idaho truck accident laws at a glance

• Filing deadline: two years for personal injury under Idaho Code § 5-219, and two years for wrongful death. Property damage claims have a three-year limit under § 5-218.
• Government claims: a written notice of claim within 180 days under the Idaho Tort Claims Act (Idaho Code §§ 6-905 and 6-906). Missing it can bar a claim against the government entity even if the two-year deadline has not passed.
• Fault rule: modified comparative fault under Idaho Code § 6-801. You are barred if your fault is 50% or more.
• Liability among defendants: Idaho generally uses several liability under § 6-803, so each defendant pays its own share, with exceptions that include parties acting in concert and vicarious liability, such as an employer for an employee.
• Non-economic damages cap: under Idaho Code § 6-1603, the cap started at $250,000 and is adjusted each July 1 based on Idaho's average annual wage. It was about $490,500 in July 2024 and about $509,000 beginning July 1, 2025. It does not apply in certain cases of willful or reckless misconduct or felony conduct, and it also applies to wrongful death.
• Economic damages: medical bills and lost income are not subject to the cap.
• Insurance system: at-fault, not no-fault. Minimum liability limits for ordinary vehicles are $25,000 per person, $50,000 per accident and $15,000 for property damage.

The 50% bar: why every point matters

If a jury finds you 30% at fault and your damages are $400,000, you can recover $280,000. At exactly 50%, you recover nothing. Insurers know this and try to push fault toward the line with arguments about speed, lane position, braking or road conditions. Photos, video, witness statements and the truck's electronic data matter. In a winter crash, road conditions and whether the truck was driving too fast for them are often central.

Idaho's cap on non-economic damages

Non-economic damages compensate for pain, suffering, emotional distress and loss of enjoyment of life. Idaho caps them in most injury and wrongful death cases, and the number changes every year, so confirm the figure for your date of injury with an Idaho attorney or on the Idaho Legislature website. The cap does not limit economic damages, and exceptions apply for willful or reckless misconduct and certain felonies. Because a trucking case may involve violations such as falsified logs or impaired driving, the evidence of the driver's and carrier's conduct can affect whether the cap applies.

Truck crashes in Idaho: what the data shows

ITD reported at least 277 traffic deaths in 2023, and preliminary ITD figures through early September 2026 show 150 deaths statewide, compared with 174 in the same period of 2025. These totals cover all vehicle types, not only trucks. Nationally, NHTSA counted 5,340 deaths in large-truck crashes in 2024, and about 70% of those killed were in other vehicles. For the latest Idaho figures, check the Idaho Transportation Department and its Office of Highway Safety.

Who may be responsible for an Idaho truck crash

• The truck driver, for speeding, distraction, fatigue, or driving too fast for icy or snowy conditions.
• The motor carrier, for the employee's actions and for negligent hiring, training, dispatch pressure or poor maintenance.
• A cargo loader or shipper, if freight was overloaded or unsecured.
• A repair shop or parts maker, if brakes, tires or other equipment failed. Mountain grades put extra demand on brakes.
• A public entity, in some cases involving road design or maintenance, subject to the 180-day notice rule.

Insurance in an Idaho truck crash

Idaho's minimum limits for ordinary vehicles are far below the cost of a serious truck injury. Under federal rules, interstate carriers hauling general freight must carry at least $750,000 in liability coverage, with higher minimums for some hazardous cargo. Many carriers carry more. Your own uninsured and underinsured motorist coverage and medical payments coverage may also apply.

Evidence that matters in an Idaho truck case

• The crash report from the investigating agency, often the Idaho State Police, a county sheriff or city police
• Photos and video of the scene, the truck, its markings, the USDOT number, road surface and weather
• Driver logs and electronic logging data. Hours-of-service rules apply, and carriers generally keep logs for only six months.
• Dash camera footage, engine data and maintenance records
• Witness names and contact information
• Medical records and bills from the first day, including air or ground ambulance transport from remote areas

You can look up the carrier's inspection and crash history in the FMCSA SAFER system. Ask a lawyer about sending a written preservation request to the carrier quickly.

What compensation may include

• Medical expenses, past and future
• Lost income and reduced earning capacity
• Pain and suffering and loss of enjoyment of life, subject to the cap
• Property damage
• In a fatal crash, funeral costs and wrongful death damages for eligible family members
• In limited cases, punitive damages, which require clear and convincing evidence and are limited by statute

No one can promise a result. The outcome depends on your injuries, the evidence, the insurance available and your share of fault.

Steps to take after a truck crash in Idaho

1. Call 911 and get medical care, even if you feel fine. In remote areas, help can take longer, so stay safe and warm.
2. Photograph the scene, the truck and its USDOT number, and note weather and road conditions.
3. Do not say you were at fault, and do not guess about speed or distance. Under the 50% bar, every word can be used.
4. Make sure a police report is filed and get the report number.
5. If a public entity may be involved, speak with a lawyer immediately because of the 180-day notice.
6. Do not give a recorded statement to the trucking company's insurer without advice.

Choosing an Idaho truck accident lawyer

Confirm the lawyer is licensed in Idaho through the Idaho State Bar, ask about commercial trucking experience and mountain or winter crash cases, and get the fee agreement in writing. Many injury lawyers work on contingency, so there is no fee unless you recover, but percentages and case costs vary. Read our guide on attorney fees and see our other state guides.
