Types of road signs

It might look countless when it comes to road symbols used in Nigeria, but actually, we can classify them into 3 main types of road signs based on their main purposes. A large number of these road signals are influenced by international regulations for traffic signs, particularly MUTCD (Manual on Uniform Traffic Control Devices) of the United States.

The first and foremost symbols you must stick to are regulatory signs which could be prohibitory or showing directions. Should you refuse to follow these regulations, our respectful policemen will certainly call you upon for a severe fine.

Next come the warning signs, reminding you of road dangers ahead. Neglecting these kind reminders means you’re ignoring your own life.

The last but not least markings are informative signs which inform vehicles of specific places, road conditions, road construction sites or speed limits for particular areas. No one is gonna punish you for not paying attention to these signals but you might waste the whole day looking for a place instead of referring to those road signs.

What meanings do these sign convey?

3...2...1. Time's up!

The first should be easy for all of you as this is one of the most basic traffic signs in every country. It indicates pedestrian crossing ahead, so you are supposed to slow down then stop before the zebra line.

The second sign demonstrates a car veering due to wet road. Yes, it is the warning for upcoming slippery road. Neglecting this notice, you and your car may end up lying still somewhere along the streets.

The third one seems to be clear-cut with instructions: "Reduce speed now" but the illustration above it is not exactly a speed limit sign. It is the marking for uneven roads.

Finally, we come to the warning for dangerous double bend. However, this illustration can't even express the hazard of some Nigerian roads like this:

Our advice

Needless to say, you should note down all these road signs in Nigeria and their meanings in your handbook so that you can check them everytime you travel on road. Should you miss a regulatory sign and be called upon by police officers, show them your road sign manual at least to prove your effort in learning them, then promise not to take your eyes off road next time!\
