HC Deb 10 February 1960 vol 617 c51W
68. Mr. Rankin

asked the Minister of Transport if he will introduce legislation in the interests of road safety requiring the maximum speed of which a passenger vehicle is capable to be related to its weight.

Mr. Marples

Though weights may be one factor to be taken into account, speed limits which vary with weight would not be readily enforceable. Past experience has shown that such speed limits are not necessarily in the interests of road safety.
