Traffic sign

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 faciliate 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. Such signs were first developed in Europe, and have been adopted by most countries to varying degrees.
