Office of Safety Research and DevelopmentNTL-SAFETY AND SECURITY-Speed LimitsNTL-SAFETY AND SECURITY-Highway SafetyFederal Highway AdministrationSpeeding, the driver behavior of exceeding the posted speed limit or driving too fast for conditions, has consistently been estimated to be a contributing factor to a significant percentage of fatal and nonfatal crashes. The U.S. Department of Transportation has instituted the Speed Management Strategic Initiative to seek more effective ways to manage the crash-related effects of speeding. In support of this initiative, this study conducted a detailed examination of recent crash data through the development of a speeding-related (SR) crash typology to help define the crash, vehicle, and driver characteristics that appear to result in a higher probability of SR crashes. Thus, the goal is to determine variables associated with SR crashes\u2014such as what, where, when, and who\u2014in order to provide guidance to the future development of new treatments and to more effectively target new and existing treatments
