On many signs there is a text telling us what to do: ‘Exit’, ‘Diversion’, and ‘Parking’. People who cannot read the text of the signs can understand them through the figure or picture. For instance, the shape of the arrow on the signs for exit helps understand the direction of the exit. Some signs convey information by means of a picture: ‘Pedestrian crossing’ and ‘Play Street’ are some examples. Then there are signs the look the same in all countries, such as the signs for “Main road” and “Give way”. One can always understand a ‘STOP’ sign even if it is written in Arabic!
