I-80 in Iowa recorded 45 deaths in large-truck crashes during 2020 to 2024, compared with 94 deaths across all fatal crashes assigned to the route in the state. Large-truck crashes accounted for 47.9% of those route deaths. The truck accident count was 41 fatal large-truck crashes. Deaths and crashes are distinct measures: a crash can involve multiple large trucks and can kill multiple people. The death count includes everyone killed in these crashes, regardless of vehicle.[1][2][3][4][5][6][7]
For this Iowa I-80 summary, a truck accident means a fatal crash involving at least one medium or heavy truck with a gross vehicle weight rating greater than 10,000 pounds, excluding buses and motor homes. Assignment uses crash-level ROUTE=1 and a parseable I-route number in TWAY_ID, the recorded trafficway identifier. These fields identify route signing and crash location; they do not describe the highway's full geographic extent.[1][2][3][4][5][6][7]

How the truck crashes on I-80 happened
For Iowa's I-80 truck accident deaths, rear-end collisions accounted for 17 deaths, or 37.8%; angle (side impact) collisions for 1, or 2.2%; sideswipes for 2, or 4.4%; and head-on collisions for 5, or 11.1%. "Not a collision with another moving vehicle" accounted for 20 deaths, or 44.4%. Manner of collision describes the first harmful event. That row means no collision with a motor vehicle in transport, including events such as 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][6]
Daytime truck accident deaths numbered 23, or 51.1%, versus nighttime's 22, or 48.9%. Urban locations recorded 9 deaths, or 20.0%; rural locations recorded 36, or 80.0%. Work-zone deaths numbered 7. These classifications count people killed in large-truck crashes, not the number of trucks or crashes.[1][2][3][4][5][6]

About these figures
The Iowa I-80 truck accident figures come from NHTSA's Fatality Analysis Reporting System, a census of fatal motor vehicle traffic crashes. Its scope requires a motor vehicle on a trafficway customarily open to the public and a death within 30 days. Nonfatal crashes and injuries are excluded. State and county fields identify crash locations, not residences.[8][6][7]
For I-80 in Iowa, crash-level ROUTE and TWAY_ID fields establish route assignment, not full highway coverage. Large-truck involvement does not establish fault. The 2020 to 2023 records are Final Files; the 2024 Annual Report File remains revisable. Readers searching for a truck accident lawyer should read these figures as location-based fatal-crash statistics. Counts cannot establish relative risk per trip or mile.[8][6][7]
