However, a 2007 study based on data from the Fatality Analysis Reporting System (FARS) of the National Highway Traffic Safety Administration concluded that between 1985 and 2002 there were "significant reductions in fatality rates for occupants and motorcyclists after the implementation of belt use laws", and that "seatbelt use rate is significantly related to lower fatality rates for the total, pedestrian, and all non-occupant models even when controlling for the presence of other state traffic safety policies and a variety of demographic factors".[24] A comprehensive 2003 US study also did "not find any evidence that higher seat belt usage has a significant effect on driving behavior." Their results showed that "overall, mandatory seat belt laws unambiguously reduce traffic fatalities."[25]
