Who died in Navajo County truck accidents

People in other vehicles accounted for 28 deaths, or 70.0% of truck accident deaths during 2020 through 2024, the largest person category. People in the large truck accounted for 11 deaths, or 27.5%. These categories describe the people killed, rather than the vehicles involved.^{[1][2][3][4][5][7]}

The row "Pedestrians, bicyclists and other people outside vehicles" records 1 death, or 2.5%. This is the FARS nonoccupant grouping, including pedestrians, pedalcyclists and other or unknown nonoccupants. The category can include occupants of parked vehicles, so its label does not establish that the person was physically outside a vehicle.^{[1][2][3][4][5][7]}

The trucks involved

The vehicle table records 36 large trucks involved in fatal crashes in Navajo County from 2020 through 2024. Truck-tractors, including semi or tractor-trailer units, numbered 26 and represented 72.2% of those large trucks. Single-unit and other large trucks numbered 10. The count of large trucks recorded as jackknifed was 1.^{[1][2][3][4][5][8][7]}

These are vehicle counts, distinct from the 30 fatal crashes and 40 truck accident deaths recorded for the period. A crash can involve multiple large trucks. The jackknife figure likewise counts trucks, rather than fatal crashes or people killed.^{[1][2][3][4][5][8][7]}

Counts are trucks, not crashes. One crash can involve more than one large truck.

How the fatal truck crashes happened

Manner of collision describes the first harmful event. Head-on accounted for 17 deaths (42.5%), rear-end for 8 (20.0%), sideswipe for 6 (15.0%) and angle (side impact) for 1 (2.5%). "Not a collision with another moving vehicle" accounted for 8 deaths (20.0%). This means no collision with a motor vehicle in transport, such as a rollover or striking a parked vehicle, fixed object, pedestrian or cyclist. Vehicles stopped in traffic can be in transport.^{[1][2][3][4][5][7]}

Separately, truck accident deaths by crash configuration were single-vehicle, 6 (15.0%); two-vehicle, 25 (62.5%); and three or more vehicles, 9 (22.5%). These group deaths by vehicle count, separately from manner of collision.^{[1][2][3][4][5][7]}

Interstates, time of day and setting

Interstate-coded truck accident deaths numbered 15, or 37.5%, during 2020 through 2024. The listed route, I-40, recorded 15 deaths. Interstate identification requires ROUTE=1 and a parseable interstate route number in TWAY_ID; the listed route counts are a coded subset, not a full road network.^{[1][2][3][4][5][7]}

Daytime, from 6 a.m. to 5:59 p.m., accounted for 18 deaths (45.0%). Nighttime, from 6 p.m. to 5:59 a.m., accounted for 22 (55.0%). Rural locations recorded 35 deaths (87.5%), while urban locations recorded 5 (12.5%). Work-zone deaths numbered 0; that figure counts people killed, not trucks or crashes.^{[1][2][3][4][5][7]}

Truck accident death rate compared with Arizona and the United States

Navajo County's truck accident death rate was 7.4 average annual deaths per 100,000 residents for 2020 through 2024. Arizona's rate was 2.0, and the national rate was 1.6. The county rate was higher than both. Listed neighboring Coconino County recorded a rate of 6.9, also lower than Navajo County's rate.^{[1][2][3][4][5][6]}

The death counts accompanying these rates are 40 for Navajo County, 737 for Arizona, 27,553 for the United States and 50 for Coconino County. Rates divide deaths by the sum of annual Census population estimates and multiply by 100,000. They do not adjust for miles driven or visitors. These are population-based rates for deaths at crash locations, not counts of residents who died.^{[1][2][3][4][5][6]}

Rates divide deaths by the sum of annual Census population estimates, so they show deaths per 100,000 residents per year. They do not adjust for miles driven or for visitors.

About these figures

FARS is a census of fatal motor vehicle traffic crashes on trafficways customarily open to the public, with an occupant or nonoccupant death within 30 days. Nonfatal crashes and injuries are excluded. For readers searching "truck accident lawyer," these counts group deaths by crash county, not home county.^[9][6][7][8]

The 2020 through 2023 figures use FARS Final Files; 2024 uses the Annual Report File and may change with its replacement by the Final File. Rates divide period deaths by summed annual Census Bureau population estimates from Vintage 2025 and multiply by 100,000. The separate July 1, 2024 estimate is not the denominator. Rates do not adjust for miles driven or visitors.^[9][6][7][8]
