Who died in San Joaquin County truck accidents

People in the large truck accounted for 9 deaths, or 8.8%. People in other vehicles accounted for 78 deaths, or 76.5%, the largest person category for truck accident deaths during 2020 through 2024.^{[1][2][3][4][5][7]}

The row "Pedestrians, bicyclists and other people outside vehicles" recorded 15 deaths, or 14.7%. This label represents the FARS nonoccupant grouping, including pedestrians, pedalcyclists and other or unknown nonoccupants. The other category can include occupants of motor vehicles not in transport, such as parked vehicles. The label therefore does not serve as a literal test of whether someone was outside a vehicle.^{[1][2][3][4][5][7]}

The trucks involved

The vehicle count for fatal truck accidents in San Joaquin County was 100 large trucks during 2020 through 2024. Truck-tractors, described in the table as semi or tractor-trailer units, numbered 64 and represented 64.0% of those large trucks. Single-unit and other large trucks numbered 36. There were 2 large trucks recorded as jackknifed.^{[1][2][3][4][5][8][7]}

Each entry in this table counts trucks, rather than crashes or deaths. A fatal crash can involve multiple large trucks, so the 100 vehicles are a different measure from the county's 95 fatal crashes and 102 deaths.^{[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 in a truck accident. Deaths were 20 for Angle (side impact), 24 for Head-on, 26 for Rear-end, 5 for Sideswipe and 1 for Other. "Not a collision with another moving vehicle" recorded 26 deaths. It means no collision with a motor vehicle in transport, which can be stopped in traffic. Examples include striking a pedestrian, cyclist, parked vehicle or fixed object, or a rollover.^{[1][2][3][4][5][7]}

Separately, crash configuration recorded 17 single-vehicle deaths (16.7%), 60 two-vehicle deaths (58.8%) and 25 deaths in crashes involving three or more vehicles (24.5%). These death shares group crashes by vehicle count, rather than manner of collision.^{[1][2][3][4][5][7]}

Interstates, time of day and setting

Interstate-coded truck accident deaths numbered 23, or 22.5%. The listed route-coded counts were 19 deaths on I-5 and 4 on I-205. These figures require an interstate route classification and a readable interstate route number; the listed routes 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., recorded 51 deaths (50.0%). Nighttime, from 6 p.m. to 5:59 a.m., also recorded 51 deaths (50.0%). Urban locations recorded 47 deaths (46.1%), while rural locations recorded 55 (53.9%). Work-zone records accounted for 4 deaths, a count of people killed rather than trucks or crashes.^{[1][2][3][4][5][7]}

Truck accident death rate compared with California and the United States

San Joaquin County's truck accident death rate was 2.6 average annual deaths per 100,000 residents for 2020 through 2024. California's rate was 1.1, and the national rate was 1.6. The county rate was higher than both.^{[1][2][3][4][5][6]}

Among the listed neighboring counties, Stanislaus County had the same rate as San Joaquin County at 2.6. Sacramento County recorded 0.8, Alameda County 0.4 and Contra Costa County 0.5. Stanislaus County had the highest rate among the listed neighboring counties, and Alameda County had the lowest.^{[1][2][3][4][5][6]}

These rates use deaths divided by the sum of annual Census population estimates, multiplied by 100,000. They measure average annual deaths per 100,000 residents and 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. Inclusion requires a motor vehicle traveling on a trafficway customarily open to the public and an occupant or nonoccupant death within 30 days. Nonfatal crashes and injuries are excluded. When reading with "truck accident lawyer" in mind, keep the grouping clear: counts follow crash location, not where people lived.^[9][6][7][8]

Data for 2020 through 2023 use FARS Final Files; 2024 uses the revisable Annual Report File. Rates divide 2020 through 2024 deaths by summed annual Census Bureau population estimates from Vintage 2025 and multiply by 100,000. They do not adjust for miles driven or visitors. The separately shown July 1, 2024 population estimate is not the rate denominator.^[9][6][7][8]
