If the driving axle, is not steering the axle has twin tyres and road-friendly suspension or each driving axle is fitted with twin tyres and the maximum weight for each axle does not exceed 8.55 tonnes.
** Distance between the rear axle of the motor vehicle and the front axle of the trailer is not less than 3 metres.

(d) Powered by a low pollution engine.
OVERLOADING OF GOODS VEHICLES
Why does overloading matter so much?
- ROAD SAFETY. Lorries which are loaded beyond their design weight are less able to stop quickly in an emergency and the steering of the vehicle can be affected.
- ROAD WEAR AND TEAR. It is estimated that the overloading of good vehicles costs the community over £50M a year through additional wear and tear to roads and bridges. Heavy axles cause proportionately far more wear and tear, and overloading drive axles (legal limit 11.5 tonnes) are the biggest single cause of excessive wear and tear on roads.
- COMPETITION. Gross overloading is unfair to the majority of law-abiding operators who accept the constraints of the plated weight limits set by the law. An operator who persistently overloads a lorry can earn additional profits amounting to thousands of pounds per annul
SOME TECHNICAL TERMS EXPLAINED
GROSS VEHICLE WEIGHT:
The total weight transmitted to the road by all the wheels on one axle.
The weight of a vehicle and its load.
The weight of a vehicle, a trailer and its load.
Either the design weight limit is given on a manufacturer’s plate or the legal weight limit is given on the Department’s plate.
Any vehicle is drawn by a motor vehicle.
A trailer pulled by a rigid vehicle.
A trailer forming part of an articulated vehicle.
A tractor unit with a semi-trailer att
Goods vehicles are subject to U.K. weight limits. The weight limits are given on the manufacturer’s plate or the Department’s plate on each vehicle. They are determined by the technical specification of the vehicle and the need to protect U.K. roads and bridges from excessive wear and tear. Vehicles over 41 tonnes operate under special arrangements. 44 tonnes is allowed for combined (road to rail) transport.
A vehicle is overloaded if it exceeds the plated weight limits. A vehicle could be overloaded on all its axles, on its gross weight and on its train weight. Each of these would be separate offences, e.g. a 3 axle articulated which exceeded the plated weights on the 1st axle, 2nd axle and gross weight would make both the vehicle operator and driver liable to three separate offences.
A vehicle or vehicle combination from 1 January 1999 can operate under either The Authorised Weight Regulations 1998 or The Road Vehicles (Construction and Use) Regulations (as amended). This leaflet has been produced by the Department for Transport, at the request of the Magistrate’s Association to give guidance to Magistrates in dealing with cases on overloading. It is not intended to be a fully authoritative statement of the law
