EXPLANATORY NOTE
(This note is not part of the Instrument and does not purport to be a legal interpretation).
These regulations amend the Road Traffic (Construction and Use of Vehicles) Regulations 2003 to update the weights and dimensional-related requirements for agricultural and forestry vehicles (including agricultural tractors, agricultural trailers, fully mounted agricultural equipment and interchangeable towed equipment). They come into effect on 1 January 2016.
National weight limits of 18 and 24 tonnes respectively are introduced for two and three axle agricultural tractors with limits of 13, 19 and 22.5 tonnes introduced for rigid drawbar single, tandem and triaxle agricultural trailers respectively. However higher limits of up to 24 and 34 tonnes are permitted for rigid drawbar tandem and triaxle agricultural trailers respectively that are plated; subject to them satisfying additional technical requirements such as a mandate for the fitment of a flexible suspension system, flotation tyres and a steered or steering axles on trailers with axle centres of 1.8 metres or greater.
As regards dimensions, the overall width of an agricultural trailer or piece of interchangeable towed equipment with a design gross vehicle weight exceeding 3.5 tonnes has been increased from 2.5 to 2.55 metres. This is to align it with the requirement that is already applicable to goods trailers. Note however that the following items are disregarded in the calculation of the overall width of an agricultural trailer or piece of interchangeable towed equipment; the projecting part of flotation tyres and associated mudguards protruding beyond the bodywork on each side of the vehicle up to a maximum of 100 millimetres, and devices associated with hydraulic rear door opening mechanisms.
Requirements are also introduced pertaining to the maximum vertical load that can be exerted on an agricultural tractor’s coupling by a trailer’s drawbar, which must not exceed the lower of the tractor manufacturer’s specifications, 3 tonnes, or 4 tonnes in the case of a ball and spoon type coupling which has been approved for this load.
Finally, combinations of agricultural tractors and trailers, where either of them is unplated, will have their maximum towable mass capped at 3 times the tractor’s unladen weight.
