Traffic signals

Flashing red light

What it means

Treat it like a stop sign: stop before the stop line, crosswalk or intersection, yield the right-of-way, and go only when it is safe. When every direction flashes red, the intersection is a four-way stop.

Traffic lights, lane-control and pedestrian signals.
