Large Truck Crash Causation Study Case Viewer
The LTCCS dataset consists of aggregate data tables. FMCSA has collaborated with the National Highway Transportation Safety Administration to develop a web-based case viewer. The viewer will allow users to filter the study dataset for specific crash types or factors and review the resulting case information. The information available for each case includes a crash summary, photographs, crash scene diagrams, vehicle and driver inspections, and other information for each involved vehicle.
