Traffic Safety: Improved Reporting Could Clarify States' Achievement of Fatality and Injury Targets, Report to Congressional Addressees [open pdf - 1MB]
From the Highlights: "Over 37,000 people were killed in traffic crashes on the nation's highways in 2017. Within the U.S. Department of Transportation (DOT), two agencies-- NHTSA [National Highway Traffic Safety Administration] for behavioral factors and FHWA [Federal Highway Administration] for highway infrastructure-- provide about $3 billion annually to states for programs to improve traffic safety. [...] GAO [Government Accountability Office] was asked to review NHTSA's and FHWA's traffic safety performance management frameworks. This report examines the extent to which: (1) states have met fatality and serious injury targets, and NHTSA's and FHWA's approaches to assessing states' achievements, and (2) states have used performance measures and targets to make traffic safety funding decisions."
