The U.S. Congress required a nationwide survey of crashes involving light passenger vehicles, with a focus on the factors related to pre crash. NHTSA’s National Center for Statistics and Analysis completed the National Motor Vehicle Crash Causation Survey. Data was collected through detailed crash investigation to assist safety advocates in evaluating and developing 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. The database includes crash narratives, photographs, schematic diagrams, vehicle information, and event data recorder data when available. Between January 1, 2005 and December 31, 2007 a total of 6,949 crashes were investigated. Of these, 5,470 cases comprise a nationally representative sample and the remaining 1,479 cases are meant to be suitable for clinical study.
