Road traffic signs can be divided into the following six main groups:
Regulatory signs regulate and control the actions of road users. They prohibit or command road users to perform certain actions. Failure to obey these signs is an offence and is punishable by a fine or imprisonment or both.
Warning signs alert road users in time to dangerous conditions on or next to the road.
Guidance signs are an aid to the road user. If the message is short, these rectangular signs are small. However, these signs used for guidance or directing as well as those, which are fairly complicated, are relatively big.
Information signs supply general information to the road user.
Road markings regulates, control and warn traffic by; defining carriageway and traffic lane limits; and to direct in a specific direction. As in the case of regulatory signs, it is an offence to disregard regulatory markings.
Traffic signals regulate vehicular and pedestrian traffic. Failure to obey traffic signals is punishable.
Although Regulatory signs are usually round, there are exceptions, such as the
octagonal stop sign,
triangular yield sign and
diamond-shaped pedestrian priority signs
A sign with a yellow background is a temporary sign, which is used to indicate a change in normal circumstances, whether for a few minutes, hours or even months. The message of temporary signs is that normal standards are not applicable and that, as a result, more attention must be given to the specific circumstances.
Typical circumstances under which temporary signs are used include:
road works, maintenance, construction and other building sites
temporary traffic accommodation or control, including school grounds and scholar patrols
