Speed Limiters


With effect from Feb 1, 2017, the Federal Government of Nigeria – through the FRSC – has mandated that ALL vehicles used for business/commercial purposes must be fitted with speed-limiting devices in compliance with extant laws before they can be legally permitted to ply the nation’s highways.

What  Are Speed Limiters? 

They are electronic devices that determine the top speed at which a moving vehicle can travel.

How Do They Work? 

A series of sensors detect how fast a vehicle is travelling, then communicates that information to the vehicle’s system that manages all the engine’s functions.  Once a pre-determined top speed is reached, the speed limiter steps in and restricts the flow of air and/or fuel to the engine, and the sparks that propel engine combustion. The consequence of this fuel/air flow restriction is the limiting of the speed of the vehicle to the pre-set (calibrated) value.

Why Install Speed Limiters?

Safety of Lives: The primary reason is to compel motorists to travel within regulated speed limits, in order to prevent deaths or grave bodily harm in the event of an accident.Obviously, the roadways would be a lot more dangerous if everyone was driving at whatever speed they choose. The faster a car travels, the more aerodynamically unstable it is due to wind resistance and forces of inertia. Any accidents that occur at top unregulated speeds are most likely to result in grave bodily injuries and even death!

Engine Protection: Speed limiters are also there to protect the engine of the vehicle itself. An engine’s lifespan degrades significantly if it is always made to travel at top speed. The increased strain makes it work harder all the time, over time, and damages it quicker.

Vehicle Tyres: Tyres wear out faster when the vehicle constantly moves at top speed.  Therefore speed limiters ensure longer tyre life-span and integrity.
