No words, just pictures!
In Afghanistan, there are roads for cars and trucks and roads for camels
and donkeys. Even if a driver is from another country, he can tell which
road is which by the picture signs.
Picture signs make it possible for almost anyone to understand basic
information. A sign showing a car going into a canal quickly warns any
driver of danger. If the sign had words, the driver would have to be
able to read the language.
Picture signs are used throughout the world. You don’t have to know even
one of the world’s 3,000 languages to understand a picture.
