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 St. Louis County truck accidents

People in the large truck accounted for 6 deaths, or 13.0%. People in other vehicles accounted for 32 deaths, or 69.6%, the largest share of truck accident deaths. The row "Pedestrians, bicyclists and other people outside vehicles" recorded 8 deaths, or 17.4%.^{[1][2][3][4][5][7]}

Pedestrians, pedalcyclists and other or unknown nonoccupants are included in the FARS nonoccupant grouping represented by that quoted label. Occupants of motor vehicles not in transport, such as parked vehicles, can fall within the other category. Whether someone was outside a vehicle is not literally tested by the grouping.^{[1][2][3][4][5][7]}

The trucks involved

The truck accident vehicle count was 47 large trucks involved in fatal crashes during 2020 through 2024. Truck-tractors, meaning semi or tractor-trailer units, numbered 29 and represented 61.7% of those trucks. Single-unit and other large trucks numbered 18. The table also records 4 large trucks as jackknifed.^{[1][2][3][4][5][8][7]}

These are vehicle counts, distinct from the 45 fatal crashes and 46 deaths recorded for the period. A crash can involve multiple large trucks, so the truck count does not represent a count of separate truck accidents.^{[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. Angle (side impact) recorded 7 deaths, or 15.2%; head-on, 6, or 13.0%; rear-end, 12, or 26.1%; and sideswipe, 6, or 13.0%. "Not a collision with another moving vehicle" recorded 15 deaths, or 32.6%. This means no collision with a motor vehicle in transport; examples include striking a pedestrian, cyclist, parked vehicle or fixed object, or a rollover. A vehicle stopped in traffic can be in transport.^{[1][2][3][4][5][7]}

Separately, truck accident deaths by crash configuration were single-vehicle, 7 (15.2%); two-vehicle, 30 (65.2%); and three or more vehicles, 9 (19.6%). These categories describe vehicle counts rather than manner of collision.^{[1][2][3][4][5][7]}

Interstates, time of day and setting

Interstate truck accident deaths numbered 30, or 65.2%. The listed route-coded counts were I-270, 14; I-44, 6; I-70, 4; and I-64, 3. Interstate identification requires ROUTE=1 and a parseable I-route number in TWAY_ID. These listed routes are a subset, not a full road network.^{[1][2][3][4][5][7]}

Daytime recorded 22 deaths (47.8%), and nighttime recorded 24 (52.2%). Daytime runs from 6 a.m. to 5:59 p.m.; nighttime runs from 6 p.m. to 5:59 a.m. Urban locations recorded 44 deaths (95.7%), rural locations 1 (2.2%), and locations with land use not reported 1 (2.2%). Work-zone truck accident deaths numbered 6; that figure counts deaths, not trucks or crashes.^{[1][2][3][4][5][7]}

Truck accident death rate compared with Missouri and the United States

St. Louis County's truck accident death rate was 0.9, compared with Missouri's 2.1 and the United States rate of 1.6. Each rate measures average annual deaths per 100,000 residents for 2020 through 2024. Among the listed neighbors, Madison County, Illinois had a rate of 2.0; St. Clair County, Illinois, 2.0; and City of St. Louis, Missouri, 1.5. The county's rate was lower than each of these listed rates.^{[1][2][3][4][5][6]}

Rates use deaths at the crash location and do not adjust for miles driven or visitors. For readers searching for a truck accident lawyer, the same grouping applies: these counts identify where crashes happened, not where the people who died lived.^{[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

Fatal motor vehicle traffic crashes are the subject of the FARS census. To qualify for inclusion, a crash must involve a motor vehicle traveling on a trafficway customarily open to the public and the death of an occupant or nonoccupant within 30 days. The crash location determines where counts are recorded, rather than the deceased person's residence. Neither nonfatal crashes nor injuries are included.^[9][6][7][8]

The 2020 through 2023 figures use FARS Final Files; 2024 uses the Annual Report File and may change with the Final 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 separate July 1, 2024 population estimate of 991,666 is not the rate denominator. Rates do not adjust for miles driven or visitors.^[9][6][7][8]
