Malfunctioning NC traffic signals will now flash red in all directions

The N.C. Department of Transportation is changing the flash mode for traffic signals when they malfunction.

They will all now flash red making it an all-way stop.

The department began modifying its traffic signals back in May so they will revert to a flashing red in every direction whenever there is a problem, such as an equipment failure.

"We are making this change to improve the safety of our intersections and provide a consistent display when the signal is not operating normally," said Nick Zinser with NCDOT .

Previously, the department used a yellow-red flashing mode when a signal malfunctioned.

The main corridor with the heavier traffic got a flashing yellow for drivers to cautiously proceed, while the side-street drivers received a flashing red.

The department will phase in this change over the next year as part of preventative maintenance.
