exas is known for its great wide open expanses of flat, open farm land, and the long straight highways connected between them. The Lone Star State is also associated with higher-than-average speed limits on those long stretches of pavement. When you're traveling Texas roads in your hot rod and put your foot down, you might become accustomed to driving over 80 miles per hour regularly. Being that Texas is one of the most dangerous states for motorists in the U.S., featuring 1.52 deaths per 100 million miles driven, the state is looking to crack down on how normalized extreme speed has become. As a result, it recently started implementing red border "final warning" speed signs, along with increased patrols during certain periods.
