Speeding - traveling too fast for conditions or exceeding the posted speed limits - is a contributing factor in 29 percent of all fatalities. In 2021, there were 42,939 fatalities on our Nation's roadways, of which 12,330 were speeding-related. This represents an increase of 8 percent from 11,428 speeding-related fatalities in 2020. Speeding is a safety concern on all roads and for all road users. Although much of the public concern about speeding has been focused on high-speed Interstates, only 13 percent (1,637) occurred on interstate highways, rural and urban combined, while 87 percent of speeding-related fatalities occurred on non-interstate roadways. Speeding is a complex issue involving engineering, driving behavior, education, and enforcement. FHWA is the lead agency accountable for the engineering actions.
