Answer:
Traffic lights, traffic signals, stoplights or robots (as they are known in South Africa)[1][2] are signalling devices positioned at road intersections, pedestrian crossings, and other locations to control flows of traffic.[3]
Allows traffic to proceed in the direction denoted, if it is safe to do so and there is room on the other side of the intersection.[6][7][8]
Red light
Prohibits any traffic from proceeding. A flashing red indication requires traffic to stop and then proceed when safe (equivalent to a stop sign).
Amber light (also known as 'orange light' or 'yellow light')
Warns that the signal is about to change to red, with some jurisdictions requiring drivers to stop if it is safe to do so, and others allowing drivers to go through the intersection if safe to do so. In some European countries (such as the UK), red and amber is displayed together, indicating that the signal is about to change to green.[
