A STOP sign with three black dots is only seen at traffic lights. It means that if the lights are not working or are flashing yellow and you are approaching this sign, you must stop and give way to traffic as though you are at an intersection with stop signs.
This sign allows you to turn left on a red light after stopping. When turning left you must give way to all traffic approaching from the right.
Left turn on red light is only permitted at intersections where the sign has been placed.
