RED FLASH...WHAT NOW?

When an intersection is in red flash, meaning the red signal light is flashing red repeatedly, you should treat the signal as a stop sign and the intersection as a four-way stop.

Once the red lights stop flashing and change to a solid, non-flashing red light, this is an indication that the intersection has returned to normal operation and you should remain at a stop and wait for the light to turn green before proceeding. In Tyler the initial solid red light will remain solid in all directions for 10 seconds to allow all vehicles to clear intersection before proceeding to the green light on the major street.
