I-15 in Utah recorded 51 deaths in large-truck crashes during 2020 to 2024, representing 30.7% of the 166 all-route deaths. Those large-truck deaths occurred in 38 fatal crashes. The truck accident death count includes everyone killed in the qualifying crashes, not just people occupying trucks. Deaths and fatal crashes are separate measures: a crash can involve multiple large trucks and can result in multiple deaths. These figures describe fatal events assigned to the Utah segment.[1][2][3][4][5][6][7]
For these I-15 truck accident statistics in Utah, a large truck is a medium or heavy truck with a gross vehicle weight rating greater than 10,000 pounds, excluding buses and motor homes. Route assignment uses the crash-level fields ROUTE=1 and a parseable I-route number in TWAY_ID. Those recorded fields identify route signing and crash location; they do not describe the highway's full geographic extent. Truck involvement does not establish fault.[1][2][3][4][5][6][7]

California's count was higher than Utah's, while Nevada's was lower.[1][2][3][4][5][6]
The other-state table contains a subset of the state segments; its entries do not constitute the route-wide total. These are location-based death counts, without adjustment for traffic exposure. They do not establish relative truck accident risk per trip or mile. A reader searching for a truck accident lawyer should keep these state-segment groupings distinct.[1][2][3][4][5][6]
About these figures
The I-15 Utah figures come from NHTSA's Fatality Analysis Reporting System, a census of fatal motor vehicle traffic crashes. Inclusion requires a motor vehicle on a trafficway customarily open to the public and an occupant or nonoccupant death within 30 days. Nonfatal crashes and injuries are excluded. State and county fields locate crashes, not residences.[8][6][7]
For I-15 in Utah, ROUTE=1 and a parseable I-route number in TWAY_ID assign crashes through route signing and recorded location, without describing the highway's full extent. Truck accident involvement does not establish fault. The 2020 to 2023 figures use FARS Final Files. The 2024 figures use the Annual Report File and can change when NHTSA replaces it with the Final File.[8][6][7]
