NHTSA’s National Center for Statistics and Analysis has completed the National Motor Vehicle Crash Causation Survey. It was a Congressionally required nationwide survey of crashes involving light passenger vehicles, with a focus on the factors related to pre-crash events. A total of 6,949 crashes were investigated between January 1, 2005, and December 31, 2007. Of these, 5,470 cases comprise a nationally representative sample. The remaining 1,479 cases are suitable for clinical study. The data collected through the investigated crashes will better assist NHTSA and other safety advocates in evaluating and developing vehicle-related crash avoidance technologies. Each investigated crash involved at least one light passenger vehicle that was towed due to damage. Data was collected on-scene for at least 600 data elements in the crash to capture information related to the drivers, vehicles, roadways, and environment. In addition, the NMVCCS database includes crash narratives, photographs, schematic diagrams, vehicle information, as well as event data recorder data when available. This document describes the SAS analysis file that is available.
