Deaths within 30 days in crashes on public roads. 2024 figures come from the FARS Annual Report File and can be revised.

Who died in Contra Costa County truck accidents

People in the large truck accounted for 3 deaths, or 9.7%. People in other vehicles accounted for 22 deaths, or 71.0%, the largest person category. The row labeled "Pedestrians, bicyclists and other people outside vehicles" recorded 6 deaths, or 19.4%.^{[1][2][3][4][5][7]}

That quoted label represents the FARS nonoccupant grouping, which includes pedestrians, pedalcyclists and other or unknown nonoccupants. Its other category can include occupants of parked motor vehicles, so the label is not a literal test of being outside a vehicle. These categories classify people who died in truck accidents, rather than counting vehicles or crashes.^{[1][2][3][4][5][7]}

The trucks involved

Fatal crashes involved 31 large trucks during 2020 through 2024. Truck-tractors (semi or tractor-trailer units) numbered 12, representing 38.7% of those large trucks. Single-unit and other large trucks numbered 19. The count of large trucks recorded as jackknifed was 0.^{[1][2][3][4][5][8][7]}

Each figure in this section counts vehicles involved in fatal crashes. It does not count deaths or separate truck accidents, and a crash can involve multiple large trucks. The truck-tractor share therefore describes the large trucks recorded in these crashes, rather than the share of people killed or the share of fatal crashes.^{[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

By manner of collision, rear-end crashes recorded 9 deaths (29.0%), angle (side impact) crashes 8 (25.8%), head-on crashes 5 (16.1%) and sideswipe crashes 2 (6.5%). "Not a collision with another moving vehicle" recorded 7 deaths (22.6%). This row means the first harmful event was not a collision with a motor vehicle in transport, such as a rollover or striking a pedestrian, cyclist, parked vehicle or fixed object. A vehicle stopped in traffic can be in transport.^{[1][2][3][4][5][7]}

Separately, crash configuration classified truck accident deaths as single-vehicle, with 6 (19.4%); two-vehicle, with 13 (41.9%); and three or more vehicles, with 12 (38.7%). Configuration describes vehicle counts, while manner of collision describes the first harmful event.^{[1][2][3][4][5][7]}

Interstates, time of day and setting

Interstate-coded truck accident deaths numbered 11, or 35.5%. The listed route-coded counts were 5 deaths on I-80, 3 on I-580 and 3 on I-680. These figures require an 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 17 deaths (54.8%), compared with 14 (45.2%) at nighttime. Daytime covers 6 a.m. to 5:59 p.m.; nighttime covers 6 p.m. to 5:59 a.m. Urban locations recorded 25 deaths (80.6%), and rural locations recorded 6 (19.4%). Work-zone deaths numbered 0; that measure counts people who died, not trucks or crashes.^{[1][2][3][4][5][7]}

Truck accident death rate compared with California and the United States

The truck accident death rate for Contra Costa County was 0.5 average annual deaths per 100,000 residents. California's rate was 1.1, and the national rate was 1.6. The county rate was lower than both. These rates cover 2020 through 2024 and use the sum of annual Census population estimates.^{[1][2][3][4][5][6]}

Contra Costa County's rate was lower than San Joaquin County's and Sacramento County's and higher than Alameda County's. The rates do not adjust for miles driven or visitors. For readers searching for a truck accident lawyer, these counts are grouped by crash location.^{[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 NHTSA's 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 dying within 30 days. Nonfatal crashes and injuries are excluded. County counts use the crash location, not the home addresses of those killed.^[9][6][7][8]

The 2020 through 2023 figures use FARS Final Files. The 2024 Annual Report File figures can change when replaced by the Final File. Rates divide deaths by summed annual Census Bureau population estimates for 2020 through 2024, using Vintage 2025, and multiply by 100,000. They express average annual deaths per 100,000 residents. The separately reported July 1, 2024 population estimate is not the rate denominator.^[9][6][7][8]
