Who died in Pima County truck accidents

People in the large truck accounted for 9 deaths, or 14.3%. People in other vehicles accounted for 38 deaths, or 60.3%, the largest person category. The row "Pedestrians, bicyclists and other people outside vehicles" recorded 16 deaths, or 25.4%. These categories describe people killed in truck accidents, rather than counts of vehicles.^{[1][2][3][4][5][7]}

The quoted label represents the FARS nonoccupant grouping, including pedestrians, pedalcyclists, and other or unknown nonoccupants. That grouping can include occupants of parked motor vehicles. It should not be read as a literal test of whether someone was outside a vehicle.^{[1][2][3][4][5][7]}

The trucks involved

Fatal truck accidents in Pima County involved 67 large trucks during 2020 through 2024. Truck-tractors, described in the table as semi or tractor-trailer units, numbered 39 and represented 58.2% of those large trucks. Single-unit and other large trucks numbered 28. The count of large trucks recorded as jackknifed was 1.^{[1][2][3][4][5][8][7]}

Each figure in this table counts vehicles, not crashes or deaths. A fatal crash can involve multiple large trucks, so the 67 large trucks and 59 fatal crashes are different measures. The jackknifed figure also describes trucks rather than a death count.^{[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. Deaths were angle (side impact), 17 (27.0%); head-on, 4 (6.3%); rear-end, 10 (15.9%); sideswipe, 8 (12.7%); and other, 2 (3.2%). "Not a collision with another moving vehicle" recorded 22 deaths (34.9%). This means no collision with another motor vehicle in transport, with examples including a pedestrian, cyclist, parked vehicle, fixed object, or rollover. A vehicle stopped in traffic can be in transport.^{[1][2][3][4][5][7]}

Separate truck accident configuration figures count deaths by the number of vehicles involved: single-vehicle, 18 (28.6%); two-vehicle, 27 (42.9%); and three or more vehicles, 18 (28.6%). These shares describe vehicle configuration, not manner of collision.^{[1][2][3][4][5][7]}

Interstates, time of day and setting

Interstate truck accident deaths numbered 30, or 47.6%. The listed route-coded counts were 25 deaths on I-10 and 5 on I-19. These figures require the interstate route classification and a parseable interstate route number; the listed routes are a coded subset, not a full road network.^{[1][2][3][4][5][7]}

Daytime recorded 35 deaths (55.6%), while nighttime recorded 28 (44.4%). Urban locations accounted for 54 deaths (85.7%), and rural locations accounted for 9 (14.3%). Work-zone deaths numbered 4. These road, time-of-day, land-use, and work-zone figures count people killed in the qualifying crashes, rather than numbers of trucks or fatal crashes.^{[1][2][3][4][5][7]}

Truck accident death rate compared with Arizona and the United States

Pima County's truck accident death rate was 1.2 average annual deaths per 100,000 residents for 2020 through 2024. It was lower than Arizona's rate of 2.0 and the national rate of 1.6. These rates use deaths at crash locations and population estimates; they do not identify deaths among county residents.^{[1][2][3][4][5][6]}

Among the listed neighboring counties, rates were 1.1 in Maricopa County, 2.4 in Pinal County, 5.7 in Cochise County, and 1.9 in Yuma County. Pima County's rate was higher than Maricopa County's and lower than the other listed neighbors' rates. Cochise County had the highest rate among the listed neighboring counties. These population-based rates do not adjust for miles driven or visitors.^{[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 a death within 30 days. Nonfatal crashes and injuries are excluded. Counts follow crash location, not where people lived. For readers searching "truck accident lawyer," the grouping to remember is the county where the crash happened.^[9][6][7][8]

The 2020 through 2023 figures use FARS Final Files; 2024 uses the revisable Annual Report File. Rates divide 2020 through 2024 deaths by the sum of annual Census Bureau population estimates from Vintage 2025, then multiply by 100,000. The separately shown July 1, 2024 population estimate is not the denominator. Rates express average annual deaths per 100,000 residents, without adjustment for miles driven or visitors.^[9][6][7][8]
