For I-80 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. Deaths include everyone killed in those crashes, not solely people in trucks. Assignment uses the crash-level ROUTE=1 field and a parseable I-route number in TWAY_ID, the recorded trafficway identifier. Those fields identify route signing and crash location rather than the highway's full geographic extent.[1][2][3][4][5][6][7]

About these figures

For I-80 in California, FARS supplies fatal-crash records, excluding nonfatal crashes and injuries. Its scope requires a motor vehicle on a trafficway customarily open to the public and a death within 30 days. State and county counts follow crash locations, not residence.[8][6][7]

The I-80 assignment uses crash-level ROUTE=1 and a parseable I-route number in TWAY_ID. These fields describe signing and location, not full highway coverage. Large-truck involvement does not establish fault. California's 2020 to 2023 figures use FARS Final Files; 2024 uses the revisable Annual Report File. Readers searching for a truck accident lawyer should keep these counts grouped by the recorded California crash location and the route assignment used here.[8][6][7]
