§ Sir J. Lambasked the Minister of Transport whether he is aware that the Government control of materials used in the manufacture of commercial motor vehicles has compelled manufacturers to use metals heavier than the light alloys and softwoods heretofore used, so that a vehicle now constructed to the same design and dimensions as a pre-war vehicle weighing less than 50 hundred weights, weighs more than 50 hundred weights; and whether he will review the speed-limit regulations so as to maintain the speed-limit of such a vehicle at 30 miles per hour, instead of requiring it to be reduced to 20 miles per hour on account of the increase in weight?
§ Captain WallaceI do not think that it would be practicable to have the same speed limit for vehicles of different unladen weights, according to whether or not certain parts had been substituted either in manufacture or in the course of repairs by parts of a heavier material.
