A traffic light, traffic signal or a stop light is a signaling device positioned at a road intersection to indicate when it is safe to wade through. The traffic signal passes on its information using a universal color code .
Traffic signs or road signs are signs erected at the side of roads to provide information to road users. With increasing speed of transport, the tendency is for countries to adopt pictorial signs or otherwise simplify and standardize signs, to facilitate international travel where language differences can create barriers and in general to reduce the risks in driving. Such pictorial signs use symbols in place of words and are usually a result of international standards.
