Understanding the events leading up to a motor vehicle crash is crucial in preventing the crash from occurring in the first place. With that objective, the U.S. Congress authorized the National Highway Traffic Safety Administration (NHTSA) of the U. S. Department of Transportation to conduct a National Motor Vehicle Crash Causation Survey (NMVCCS). NHTSA's National Center for Statistics and Analysis (NCSA) has completed a nationwide survey of crashes involving light passenger vehicles, with a focus on the factors related to pre-crash events--a survey of critical importance to the stakeholders in traffic safety. A sound methodology, which has been reviewed by a panel of experts, was used for this purpose. A nationally representative sample of crashes was investigated from 2005 to 2007. NMVCCS ceased investigating crashes on December 31, 2007. The data collected through the investigated crashes will better equip NHTSA and other safety advocates to evaluate and develop vehicle-related crash avoidance technologies. |
