When it comes to speed limit rules on highways, majority of people think it's a figure that the FRSC just wakes up one day and decided to chose just to reduce overspeeding on the roads. Nigeria as a case study has been using highway speed limit of 100Km/h for years now.

In fact some people think our highway speed limit has a lot to do with the road surface or our road surface is one of the factor that 100Km/h speed limit is suggested. Meanwhile, it is a pure misconception.

The truth is, in road design, there is what we call PROFILES design/Vertical Alignment. At the stage of generating your profile, there is a space where the SPEED LIMIT of the road is specified at various chainage especially where vertical curve: Sag or Crest occurs for the Finished Ground. Which means, the highway speed limit is part of the road design.

In short, most Nigeria highways were designed based on 100Km/h speed limit. So, if you're a type who drives and think your car is in good conditions to speed above 100Km/h, note that you're not just risking your life but you're also going against the design protocol of the road itself.

Just as your car was designed to run on petrol and you dare not try to put kerosene to avoid damages, so also the road itself was designed with 100km/h and don't dare to go beyond to avoid lost of life and car damages.
