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.

“When politicians and politically minded people pay too much attention to literature, it is a bad sign—a bad sign mostly for literature.... But it is also a bad sign when they don’t want to hear the word mentioned.”
—Italo Calvino (1923–1985)
