§ 59. Sir C. Rawson
asked the Minister of Transport how many local authorities have made use of the apparatus mounted on motor-cycle and side-car combinations for measuring road-surface resistance to skidding; and whether, in view of the fact that slippery roads reduce the braking efficiency of cars, he will take steps to test roads, with or without the consent of the 26 local authority, simultaneously with the testing of the braking efficiency of cars?
Tests have been made by means of this type of apparatus in the areas of 41 local authorities. It is not necessary to test the resistance to skidding of a road in order to determine whether the brakes of a vehicle are efficient.
