Explanation:
Warning signs are primarily for the protection of drivers and pedestrian. In traffic regulations, there are about eight different types of colours used in traffic signs. I will be explaining three(3) colour signs and their meaning below;
(1).YELLOW: yellow colour in signs is used as a warning sign for dangers ahead.
(2). BLUE: blue colour is used as a guide sign. This colour is used to show direction and distance.
(3). RED: red colour signs are regulatory signs.
In addition to the colour of signs given above, orange colour is also used for warning.
