Large Truck Crash Causation Study

Researchers and analysts obtained access to unprecedented detail about the events surrounding truck crashes that were not available anywhere else. The Federal Motor Carrier Safety Administration posted online the database from its groundbreaking Large Truck Crash Causation Study (LTCCS). FMCSA conducted its own analysis as well as sponsored non-governmental organizations who were interested in analyzing the study results. The data from the study, along with the original report to Congress, data tables, and other study information, may be downloaded in several formats from the LTCCS Web site.
