I-15 in California recorded 69 deaths in large-truck crashes from 2020 to 2024, alongside 365 deaths from all fatal crashes assigned to the route. Large-truck involvement accounted for 18.9% of those route deaths. The large-truck death count came from 63 fatal large-truck crashes. These truck accident statistics count everyone killed in the qualifying crashes, including people who were not occupants of the large truck.[1][2][3][4][5][6][7]

For I-15 in California, a truck accident means a fatal crash involving at least one medium or heavy truck with a gross vehicle weight rating greater than 10,000 pounds; buses and motor homes are excluded. Assignment uses the crash-level route fields: ROUTE=1 and a parseable I-route number in TWAY_ID, the recorded trafficway identifier. Those fields identify route signing and crash location. They do not describe the full geographic extent of I-15 or establish which participant was at fault.[1][2][3][4][5][6][7]

About these figures

For I-15 in California, NHTSA's FARS supplies fatal-crash data only; nonfatal crashes and injuries are excluded. Counts follow recorded crash locations, not residence. Crash-level ROUTE and TWAY_ID fields assign crashes to I-15, identifying route signing and location rather than the highway's full geographic extent. Large-truck involvement does not establish fault, and deaths include people other than truck occupants.[8][6][7]

California I-15 figures for 2020 to 2023 use FARS Final Files. The 2024 Annual Report File remains revisable when NHTSA replaces it with the Final File. If you arrived with the phrase "truck accident lawyer" in mind, read these figures according to their stated grouping: deaths and fatal crashes assigned to this route in California.[8][6][7]
