Traffic light (also popularly known as signal, traffic light and beacon or light signal) is an instrument used to control vehicle and pedestrian or pedestrian traffic in large cities almost all over the world. It uses a simple language and, therefore, it is easy to assimilate. Those who cannot differentiate between the colors very much distinguish the controls in order, which is the same in most parts of the world: below, where the green is, indicates that the driver can continue following the path; in the middle, yellow, slow down; and the one on top, the red one, it's time to stop.
