The Federal Road Safety Commission is set to enforce the speed limiting device in vehicles from October 1.
Corps Marshal Boboye Oyeyemi told stakeholders in Abuja that the implementation and enforcement of the device witnessed four postponements from its initial launching date of June 1, 2015, before its final approval.
Mr Oyeyemi said the corps would do this for the next three to six months to achieve enforcement and compliance so as to compel commercial vehicles to install the device.
He said the FRSC was only concerned about commercial vehicles installing it for now, adding that with time the enforcement would extend to private vehicles.
The device, according to FRSC was made possible with the collaboration of Standard Organisation of Nigeria.
