Fatal truck accidents assigned to I-40 in Arizona recorded 88 deaths during 2020 to 2024, representing 54.3% of the 162 deaths recorded on the route in the state. Those large-truck deaths occurred in 72 fatal crashes. The truck accident death count includes everyone killed in a qualifying crash, not just people occupying the large truck. These figures describe crashes recorded on the Arizona segment through the crash location and route fields.[1][2][3][4][5][6][7]

For I-40 in Arizona, 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 requires ROUTE=1 and a parseable I-route number in TWAY_ID, the crash's recorded trafficway identifier. The resulting counts describe route-coded crash locations; those fields do not establish the full geographic extent of I-40 in Arizona.[1][2][3][4][5][6][7]

How the truck crashes on I-40 happened

Rear-end crashes accounted for 34 truck accident deaths, or 38.6%, the largest manner-of-collision count among the listed rows. Head-on crashes recorded 11 deaths (12.5%), sideswipe crashes 7 (8.0%), and angle (side impact) crashes 5 (5.7%). Other recorded 1 death (1.1%).[1][2][3][4][5][6]

The row "Not a collision with another moving vehicle" recorded 30 deaths (34.1%). It means the first harmful event was not a collision with a motor vehicle in transport, such as a rollover or striking a parked vehicle. A vehicle stopped in traffic can be in transport.[1][2][3][4][5][6]

Daytime and nighttime each recorded 44 truck accident deaths (50.0%). Daytime runs from 6 a.m. to 5:59 p.m.; nighttime runs from 6 p.m. to 5:59 a.m. Rural locations recorded 80 deaths (90.9%); urban locations recorded 8 (9.1%). Work-zone deaths numbered 4.

About these figures

For I-40 in Arizona, FARS counts fatal motor vehicle traffic crashes on trafficways customarily open to the public when an occupant or nonoccupant dies within 30 days. Nonfatal crashes and injuries are excluded. Truck accident counts follow crash locations, not residence. Readers searching for a truck accident lawyer should keep that grouping in mind when reading these figures.[8][6][7]

Arizona's I-40 assignment uses crash-level ROUTE=1 and a parseable I-route number in TWAY_ID. These fields identify route signing and crash location, not the highway's full geographic extent. Large-truck involvement does not establish fault. The 2020 to 2023 figures use FARS Final Files; the 2024 Annual Report File remains revisable when NHTSA replaces it with the Final File.[8][6][7]
