Wrong Way sign on a freeway entrance

Wrong-Way Drivers

ADOT's efforts to prevent wrong way drivers include installation of a pilot-project detection system, hundreds of larger and lowered "Wrong Way" and "Do Not Enter" signs, as well large, white "right way" arrows on off-ramps with reflectors that glow bright red when a vehicle is traveling the wrong way.
