Further lamps must be displayed to ensure that the distance between side marker lamps does not exceed three metres .
Regulation 43 exempts from these requirements a combination of vehicles if it has broken down and single vehicles carrying a long or wide load.as laid down in Regulation 35 of the Motor Vehicles (Construction and Use) Regulations 1973.

In this case, one lamp must be carried on each side not forward of and not more than 1,515mm (5ft) from the rear of the vehicles and another not forward of and not more than 1,515mm to the rear of the centre point of the overall length of the load,
