Source: NHTSA Fatality Analysis Reporting System (FARS), 2020-2023 Final File and 2024 Annual Report File (ARF), national data files downloaded from NHTSA on November 3, 2026. A crash counts for a road under the trafficway the reporting agency recorded; the same street with and without a route number is one row, and a route recorded without a street name keeps its own row; roads with fewer than two fatal crashes are not listed. The 2024 figures are NHTSA's first release for that year and may change in its Final File.

How to cite these figures: Ask Legal Matters, "Fatal crashes in Ada County, ID, 2020-2024," compiled from NHTSA FARS (2020-2023 Final File and 2024 Annual Report File (ARF)), https://asklegalmatters.com/injury-guides/idaho/ada-county/, checked November 3, 2026.

The yearly count was 17 in 2020, 21 in 2021, 19 in 2022, 31 in 2023 and 29 in 2024; 50% of the crashes happened after dark. 31 involved a pedestrian, cyclist or other person outside a vehicle, and 45 happened at or near an intersection.

A high share of the fatal crashes in Ada County involve pedestrians or cyclists. Those claims often turn on where the person was crossing or riding, the lighting and whether the driver should have seen them, so photos taken at the same time of day and any nearby camera footage matter.

Reporting the crash in Idaho

In Idaho, the driver must immediately notify the police of a crash that injures or kills anyone or damages any one person's property by more than $1,500: the local police inside a city, otherwise the county sheriff or the nearest Idaho State Police office (Idaho Code § 49-1305). Drivers do not file a state report; the investigating officer sends one to the Idaho Transportation Department.

Communities in Ada County

Each community below has its own guide with the local court, insurance rules and every type of injury claim.

Smaller communities in Ada County include Boise. Residents of these areas follow the same Idaho rules, use the same Ada County District Court, and can request a free case review from anywhere in the county.

Idaho's two years statute of limitations

Idaho generally gives an injured person two years from the date of injury to file a personal injury lawsuit (Idaho Code § 5-219(4)); medical malpractice is different (two years). Wrongful death claims follow their own deadline, which can differ from the one above. Claims against a city, county, school district or state agency follow separate and often much shorter deadlines. Once the deadline passes, the Ada County District Court will dismiss the case regardless of how clear the fault was, so the practical rule in Ada County is to get legal advice early.

How fault works: modified comparative negligence (50% bar)

Idaho follows modified comparative negligence (50% bar). In plain terms, you can recover only if you were less than 50% at fault, and your award is reduced by your share of fault. Insurance adjusters apply this rule from the first phone call, which is why the way an accident is described and documented in the days after it happens in Ada County has a direct effect on what a claim is worth.

Auto insurance in Idaho: an at-fault system

After a crash in Ada County, the at-fault driver's liability insurance is the primary source of compensation. Idaho requires drivers to carry only 25/50/15 in coverage (thousands of dollars for bodily injury per person, per accident, and property damage), which serious injuries quickly exhaust. Underinsured motorist coverage on your own policy and claims against additional responsible parties often make the difference in Ada County cases.

Where Ada County injury cases are filed

Lawsuits arising from accidents in Ada County are typically filed in the Ada County District Court, the trial court of general jurisdiction for Ada County, although cases can sometimes be filed where the defendant resides or does business, and claims against out-of-state trucking companies or manufacturers may end up in federal court. Most claims settle before trial, but the credible ability to try a case in Ada County is what moves insurers to pay fair value.

Workplace injuries: Idaho Industrial Commission

Employees injured on the job in Ada County are generally covered by Idaho workers' compensation, administered through the Idaho Industrial Commission. Report the injury to your employer within 60 days — a late report can delay or put the claim at risk, and the exceptions vary by state — then file the formal claim within one year. Workers' compensation does not pay for pain and suffering, so when a third party such as a subcontractor, driver or equipment manufacturer caused the injury, a separate personal injury claim is often worth pursuing alongside it.

Frequently asked questions

Is there 2025 fatal crash data for Ada County?

Not yet from the federal census of fatal crashes. The newest national file is NHTSA's 2024 Annual Report File, the first release for 2024, used here with the 2020-2023 Final Files; NHTSA had not published 2025 FARS data when this page was updated on November 3, 2026. FARS counts every crash on a public road in which someone died within 30 days, and a crash counts for Ada County when the reporting agency coded it there. Some cities and states post newer counts on their own crash dashboards, which use their own definitions.

How long do I have to file an injury lawsuit in Ada County?

Generally two years from the date of injury under Idaho law (Idaho Code § 5-219(4)); medical malpractice claims generally have a two years limit, and claims against the county, a city or the state require notice much sooner.

Which court handles injury cases in Ada County?

The Ada County District Court is the trial court for Ada County. Some claims may be filed where the defendant lives or does business, and claims against out-of-state companies can be removed to federal court.

I live in a small town in Ada County. Do the same rules apply?

Yes. Idaho's deadline, fault rule and insurance requirements apply everywhere in the state. Smaller communities simply have fewer local attorneys, which is one reason people use a free case review request to reach attorneys who handle cases across Ada County.

What if I was partly at fault?

Idaho applies modified comparative negligence (50% bar): you can recover only if you were less than 50% at fault, and your award is reduced by your share of fault.

Is Ask Legal Matters a law firm?

No. Ask Legal Matters is a personal injury lead-generation service that collects free case review requests from injured people in the United States and shares them with independent attorneys and law firms. It is not a law firm and does not give legal advice. Requests may be shared with independent attorneys and legal services partners who handle inquiries in Idaho, and submitting a request does not hire an attorney.
