About these figures

The Montana I-90 truck accident figures come from NHTSA's FARS, a census of fatal motor vehicle traffic crashes. Its scope requires a motor vehicle on a trafficway customarily open to the public and a death within 30 days. Nonfatal crashes and injuries are excluded. Counts follow crash locations, not residence.^[8][6][7]

For I-90 in Montana, crash-level route assignment uses route signing and the recorded trafficway identifier, not full highway coverage. Large-truck involvement does not establish fault. The 2020 to 2023 figures use Final Files; 2024 uses the revisable Annual Report File. Readers searching for a truck accident lawyer should read these figures as location-based fatal-crash statistics. A truck accident death count includes everyone killed in qualifying crashes.^[8][6][7]
