Sources and authorities
Two federal publications. Every figure above appears in one of them and is shown with its data year.
Federal crash data publications
- Federal Motor Carrier Safety Administration, Large Truck and Bus Crash Facts 2022, report number FMCSA-RRA-24-001, Crash Data Analytics Division, published September 2025. Source of the figures for large trucks involved in fatal crashes, the involvement rate per 100 million miles traveled, and the injury crash estimate drawn from NHTSA CRSS data. Also the source of the statements that the federal files describe the events and details of crashes but do not include data on crash causation or fault, that FARS is the most reliable national crash database but covers only fatal crashes, and that the agency's own crash file is intended as a census while some States under-report and some over-report. FMCSA.
- National Highway Traffic Safety Administration, Traffic Safety Facts, 2022 Data: Large Trucks, published July 2024. Source of the number of people killed, the proportion who were occupants of other vehicles, the weekday proportion, and the three driver comparisons on blood alcohol concentration, previously recorded crashes, and previous license suspensions or revocations. National Transportation Library.
On the publication lag, stated first rather than last. The most recent complete federal edition covers 2022 and was published in September 2025. A page carrying a current year in its title while presenting data from four years earlier owes the reader that fact in the opening section rather than in a footnote, which is why section one exists and why it is section one.
On the two headline numbers. They are not alternative estimates of the same quantity. FMCSA counts vehicles involved; NHTSA counts people killed. A single crash can involve more than one large truck and can kill more than one person, so neither can be derived from the other and quoting them interchangeably, which is extremely common, produces sentences that do not mean what they appear to.
On figures that cut against the reader. Section six carries three comparisons that complicate rather than support the usual account of truck crashes, including that large truck drivers in fatal crashes are far less likely than other drivers to have been impaired. They are included because a research page that published only the helpful half of a dataset would be advocacy, and because they come from the same table as the figures that point the other way.
On retrieval. Every figure on this page was taken from the publication named beside it during the writing of this page. None was written from memory and then attributed. If a later editor updates any number, the correct method is to retrieve the current edition rather than adjusting a figure and leaving the citation in place.
