Road traffic signs serve several purposes: some road signs are placed on roads to point out directions to motorists; some are placed there to ensure the safety of motorists and pedestrians; some are there to give us an idea of what to expect ahead of us, etc.
Technically, road signs are traffic languages. They communicate specific messages to motorists and pedestrians.
Every motorists – and in some cases, pedestrians – are expected to have an understanding of what these signs represents.
It is because of this that the teaching of road traffic signs and their meanings are an essential topic taught at driving schools. Unfortunately, most motorists in Nigeria did not pass through formal driving schools.
Road signs are typically represented as symbols or annotations. In Nigeria, there is an enormous lack of understanding of what these symbols used in road signs represent.
