where is the green light on a traffic light
Traffic light Aspect is a term referring to the light that faces the drivers. A typical vertical traffic signal has three aspects, or lights, facing the oncoming traffic, red on top, yellow below, and green below that. Generally one aspect is illuminated at a time. In some cases, a fourth aspect, for a turn arrow for example, is below the three lights or aspects in more complicated road traffic intersections.
School bus traffic stop laws Generally, if a stopped school bus is displaying a flashing, alternating red lamp, a driver of a vehicle meeting or overtaking the stopped bus from either direction (front or back) must stop and wait until the bus moves again or the red light is off.[1] Police officers, school crossing guards, and even school bus drivers themselves may have the power to wave traffic on, even when a red light is flashing.
