For the fourth year in a row, the numbers of vehicle crashes in Texas involving both injuries and fatalities have risen. Both numbers began rising dramatically in 2012, when Texas highway speed limits were raised. “With new safety features on vehicles and the 55 mile per hour speed limit, traffic fatalities had gone down every year,” said Mark Hanna, a spokesman for the Insurance Council of Texas. “As soon as the speed limits began rising on Texas highways, so did the number of traffic injuries and fatalities.”
