A Speed limiter is an engine control device which interfaces with the engine control unit (ECU - some people call it brain box) and speedometer of a vehicle to restrict the engine speed once the vehicle reaches a pre-configured speed. A speed limiter may work by reducing the airflow into the vehicle engine, the fuel supply to the engine or adjust the timing of the engine's ignition system to keep the vehicle from exceeding the preset speed limit imposed by the limiter.

Speed limiters are common on many types of vehicles and are usually compulsory devices equipment on trucks and commercial vehicles in some jurisdictions. Different government agencies may enact Laws that require speed limiters for use in commercial vehicles. The main reason for installing speed limiters is that limiting the speed of these type of vehicles may improve highway safety. In the scenario of a passenger car, the reason for speed limiters is generally to prevent the vehicle from exceeding speeds that may affect certain design limitations and improve safety of the vehicle.

The Federal Road Safety Commission in line with a resolution reached with National Automotive Design and Development Council of Nigeria (NADDC), Standard Organization of Nigeria (SON) and other stakeholders has made it mandatory for all vehicles in Nigeria with emphasis on commercial vehicles (buses, trailers, tankers and trucks) to install Speed Limiting Device before a deadline of October 1st, 2016.

And if the vehicle does not have an Engine ecu what happens? tongue

Smart speed limiters will be GPS enabled, that way you do not have to interfere with the vehicles electronics, other than the limiting part (fuel cut)

I have it installed and I am pissed. 'oyibo way raise speedometer reach 220km/h are they fools?'.
Scenarios can occur when I would have to drive beyond 90,like forest fires and robberies. Now i'm just a sitting duck!! Speeding should be the decision/discretion of the trained driver. embarassed

@Op, how much does this device cost? FRSC said it's N45K to N52k depending on your type of vehicle. If your vehicle does not have the sensors necessary for the installation, I don't know how they'll do it to install it.
Also information from a reliable source said the actual cost of that device is N5K but after adding money for different people and for different purposes, it came up as high as N45000.

My question about this device is, in a situation where armed robbers are chasing the vehicle with the speed limit on the highway, how will the vehicle run in other not to be caught by those robbers.

The major cause of accident in Nigeria is bad roads. Is it not where you have smooth road that you overspeed? Also let the price of this device come as low as N8000 so that motorists will be able to buy it.

The op forgot to tell us the cost of installing it and it's effect on the vehicle besides limiting speed.
If it was compulsory abroad, all used buses and trucks imported would have come with them.
What's the use of a truck with speed limiter when the roads are full of pot holes to limit speed already.
The device costs upwards of N40000 to install, not to talk of the process involved.
I see it as another meaningless scheme to enrich some party contractor just like the issue of plate number.

GPS enabled device is not approved by the FRSC.
