Crash Data Research

Why We Publish This

Federal crash data is public, but it is published in formats that are difficult to work with, so much of what it shows never reaches the people it is about. We analyse it and publish the results in full: the finding, the method, the year, and the underlying aggregate as a downloadable file. Every study here is free for journalists, researchers and anyone else to republish with attribution. We are a lead-generation service, not a law firm, and none of this is legal advice.

Common Questions

Frequently Asked Questions

Yes. Every study on this page is free to republish, including the charts, the tables and the downloadable data, with attribution to Cash4Crashes and a link to the study. The underlying federal datasets are public and are not owned by us. If you need a cut we have not published, such as a specific state, county or metro area, or an earlier year for comparison, email help@cash4crashes.com and we will run it.

Primarily the NHTSA Fatality Analysis Reporting System, which is a census of every fatal motor-vehicle crash on US public roads, and the Federal Motor Carrier Safety Administration crash file, which covers commercial truck and bus crashes including non-fatal ones. Both are public federal datasets. Each study names the exact source and year it used, and the script that produced its figures is published alongside it so the analysis can be reproduced.

No. The federal crash files record what happened and who was hurt. They do not record fault, and we do not infer it. Our analyses describe outcomes, which is a separate question from responsibility. Fault in any individual crash is determined by investigating that crash, not by national statistics.

FARS is published annually by NHTSA and we refresh the analyses when a new year becomes available. The FMCSA crash file updates on a rolling basis. Each study shows the year it covers and the date it was last updated, so you can see how current a figure is before quoting it.
