The State of Arizona is embarking on the safety of wrong way drivers but doing what no one else has; wrong way vehicle directional system. The Arizona Transportation Board approved a contract to install the system on Interstate 17 by using a thermal system. The signal will alert oncoming drivers and the highway patrol of vehicles traveling the wrong direction. This system will be installed later this month on a 15-mile stretch of the interstate and testing will continue until the early part of 2018. ATB will follow this and pass long updates as they come.
