asked the Minister of Transport if he intends to make it compulsory to have fog lights fitted to front and rear of all heavy goods vehicles; and, if not, what is the reason for his decision.
Rear fog lamps are already compulsory for all new vehicles, including heavy goods vehicles. These enable vehicles to be seen more easily by following drivers when visibility is bad. This function is fulfilled for oncoming drivers by the use of dipped headlights. Front fog lights can certainly make driving easier in some circumstances, but I have no evidence to suggest that there would be significant road safety benefits in requiring their compulsory fitment.
