Regulatory Signs

Road Signs in Nigeria And Their Meaning - Regulatory Signs

Regulatory signs are also known as traffic control signage, these signs are less informational and more directorial. For travellers entering a new town, unfamiliar with unique traffic laws and penalties, regulatory signs are often the most important. They include stop signs, yield signs, turn and lane use signs and traffic signal signs (“No Turn on Red,” for instance). If you’re a driver looking for curbside parking, regulation signs provide the information you need to avoid a citation. Regulatory signs also encompass detour signs, weigh station signage, and railroad crossing signs.

Warning Signs

With the rate of accidents, road projects, and car breakdowns on the roads, the need for warning Given becomes important. This helps other road users to limit speed as they approach such areas. Warning signs include turn and curve warnings, intersection signs, merge and lane transition warnings, bridge clearances, divided highway warnings, hill warnings, and pedestrian crossing notices among others. Almost every warning sign is symbol-based, with little to no text.

Guide Signs

As one drive, guide signs are the holy grail of navigation. It helps motorists navigate interstate highways without taking their eyes off the road. It’s true that GPS navigation can help,  but fumbling with your phone while approaching a confluence of two or three highways can be dangerous. These guide signs come in form of diagrammatic guide signs, roadway junction signs, destination distance signs, and mile makers.


These are some of the most seen traffic signs, Both the shape and colour are important to how a stop sign is recognized and understood. No other sign is of an octagon shape, and no other sign is red in colour. This is done because of the importance a stop sign has on traffic safety. It is used to alert drivers of intersections and other areas where traffic may be travelling in opposite or crossing directions.
