The Weighing of Motor Vehicles (Use of Dynamic Axle Weighing Machines) Regulations 1978
These Regulations make provision for facilitating the use of dynamic axle weighing machines in order to ascertain the weights transmitted to the road surface by the wheels of each axle of a motor vehicle or trailer, and, in consequence, the gross weight of the motor vehicle or trailer. The manner in which the weighing is to be carried out is indicated in Regulation 3. The limits of presumed accuracy for dynamic axle weighing machines are specified in Regulation 4 and Regulation 5 prescribes a form of certificate of weight to be issued when a dynamic axle weighing machine is used.
