HC Deb 10 December 1963 vol 686 c80W
Dr. Bennett

asked the Minister of Transport whether he will take steps to discourage the overloading of underpowered heavy vehicles and to encourage the use of fully-powered vehicles, if necessary by differential rates of licence dues.

Mr. Marples

A minimum power to weight ratio is one of the standards now being considered in working out a scheme for prescribing an authorised gross weight for every goods vehicle.
