From 2020 through 2024, federal crash records list 52 fatal crashes in Cascade County, in which 58 people died. The roads with the most were US-89 with 7 fatal crashes, I-15 with 7 and US-87 (street name not recorded) with 5.

The yearly count was 12 in 2020, 12 in 2021, 9 in 2022, 8 in 2023 and 11 in 2024; 44% of the crashes happened after dark. 5 involved a pedestrian, cyclist or other person outside a vehicle, and 16 happened at or near an intersection.

Fatal crashes are the most serious outcome on these roads; many more crashes cause injuries without a death. Whatever the severity, the police crash report, photos of the scene and prompt medical records are the starting evidence for a claim.

In Montana, the driver in a crash that injures or kills anyone, or causes apparent property damage of $1,000 or more, must notify the police immediately: the local police inside a city, otherwise the county sheriff or the nearest Highway Patrol office (MCA 61-7-108). Unless a law enforcement officer investigated and reported the crash, the driver must also send a written report to the Department of Justice within 10 days (MCA 61-7-109).

Smaller communities in Cascade County include Belt, Black Eagle, Cascade, Fort Shaw, Malmstrom A F B, Monarch, Neihart, Sand Coulee, Simms, Stockett, Sun River, Ulm, Vaughn. Residents of these areas follow the same Montana rules, use the same Cascade County District Court, and can request a free claim review from anywhere in the county.

Montana generally gives an injured person three years from the date of injury to file a personal injury lawsuit (Mont. Code Ann. § 27-2-204(1)); 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 Cascade County District Court will dismiss the case regardless of how clear the fault was, so the practical rule in Cascade County is to get legal advice early.

Montana follows modified comparative negligence (51% bar). In plain terms, you can recover as long as you were not more 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 Cascade County has a direct effect on what a claim is worth.

After a crash in Cascade County, the at-fault driver's liability insurance is the primary source of compensation. Montana requires drivers to carry only 25/50/20 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 Cascade County cases.

Lawsuits arising from accidents in Cascade County are typically filed in the Cascade County District Court, the trial court of general jurisdiction for Cascade 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 Cascade County is what moves insurers to pay fair value.

Employees injured on the job in Cascade County are generally covered by Montana workers' compensation, administered through the Montana Department of Labor & Industry. Report the injury to your employer within 30 days of the accident (Mont. Code Ann. § 39-71-603) — 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.
