The rules of the road, a universal visual semiotics

The rules of the road form part an international willingness to simplify the understanding of road regulations worldwide. There is still an attempt to harmonise all regulations, but some countries are reluctant to do so as they fear a loss of their domestic sovereignty. Indeed, with the increase in car use for private or professional reasons, accidents have become one the central issue in international politics; and one way to curb accidents is said to have a universal visual road semiotics. However as this cultural discernment of road signs in civil society (i.e. visual encoding) has become popular, many other forms of use have derived from it for other purposes than road regulations.
