I-55 truck accident deaths in Missouri by year

Annual truck accident deaths on I-55 in Missouri rose from 2 in 2020 to 5 in 2021 and 8 in 2022. The count then fell to 6 in 2023 and 3 in 2024. Among these years, 2022 had the highest large-truck death count, while 2020 had the lowest. The 2024 count was higher than the 2020 count.^{[1][2][3][4][5]}

All deaths on the route followed a different sequence: 12 in 2020, 23 in 2021, 21 in 2022, 17 in 2023 and 24 in 2024. For this measure, 2024 was the highest year and 2020 the lowest. All-route deaths rose from 2023 to 2024, while deaths in large-truck crashes fell. The annual columns count deaths, rather than fatal crashes.^{[1][2][3][4][5]}

Crashes are placed on the route by the trafficway identifier recorded for each fatal crash. 2024 is the Annual Report File.

The other-state table supplies a subset of segments, while the route total is supplied separately. These truck accident counts are not traffic-adjusted risk rankings and cannot establish relative risk per trip or mile. A search for a truck accident lawyer should keep these geographic groupings distinct.^{[1][2][3][4][5][6]}

About these figures

For I-55 in Missouri, NHTSA's Fatality Analysis Reporting System supplies fatal-only truck accident data; nonfatal crashes and injuries are excluded. Eligibility requires a motor vehicle on a trafficway customarily open to the public and a death within 30 days. Counts follow crash locations, not where people lived.^[8][6][7]

Missouri's I-55 assignment uses crash-level ROUTE=1 and a parseable I-route number in TWAY_ID. Those fields describe route signing and location, not the highway's full extent. Large-truck involvement does not establish fault. The 2020 to 2023 figures come from FARS Final Files. For 2024, the source is the Annual Report File, whose figures can change when NHTSA replaces it with the Final File. Death counts remain distinct from fatal-crash counts.^[8][6][7]
