What is the flashing red traffic light for?
Flashing red lights may be permanent or temporary (e.g. when the programmed sequence fails).A flashing red light means STOP, then proceed when safe.If it is a 4-way flashing red, cross traffic will also stop, and the intersection becomes identical to one with stop signs. This is a safety feature in some programmed signals. If only one direction has the flashing red (such as a road that intersects a busy highway), the traffic entering the highway must stop, and never has the right-of-way.* Some international traffic signals use a flashing red in place of steady red, to attract the attention of drivers where there is a profusion of commercial lights.
