Oklahoma DOT Tests Wrong Way Alert System

The Oklahoma Department of Transportation is testing a wrong-way detection and alert system.

The tools will be on six ramps along Interstate 40 in Eastern Oklahoma. Thermal cameras will be used to detect when a vehicle enters an exit ramp in the wrong direction and activate flashing lights on "Wrong Way" signs that are already posted. Installing "Do Not Enter" signs that are internally lit allows these warnings to be better seen at night.
