Traffic Sign
Traffic signs or road signs are signs erected at the side of or above roads to provide information to road users. The earliest signs were simple wooden or stone milestones. Later, signs with directional arms were introduced, for example, the fingerposts in the United Kingdom and their wooden counterparts in Saxony.
With traffic volumes increasing since the 1930s, many countries have adopted pictorial signs or otherwise simplified and standardized their signs to facilitate international travel where language differences would create barriers, and in general to help enhance traffic safety. Such pictorial signs use symbols (often silhouettes) in place of words and are usually based on international protocols. Such signs were first developed in Europe, and have been adopted by most countries to varying degrees.

Famous quotes containing the words traffic and/or sign:
“Cry;and upon thy so sore loss
Shall shine the traffic of Jacobs ladder
Pitched betwixt Heaven and Charing Cross.”
—Francis Thompson (18591907)
“It is at the same time by poetry and through poetry, by and through music, that the soul glimpses the splendors found behind the tomb; and when an exquisite poem brings tears to ones eyes, these tears are not the sign of excessive pleasure, they are rather witness to an irritated melancholy, to a condition of nerves, to a nature exiled to imperfection and which would like to seize immediately, on this very earth, a revealed paradise.”
—Charles Baudelaire (18211867)
