§ Mr. Pageasked the Minister of Transport and Civil Aviation if he will give an estimate of the reduction in road accidents when a "Halt" sign or a "Slow" sign is placed at a road intersection; and whether the one sign or the other has been found to be the more effective in bringing about such a reduction.
§ Mr. Watkinson"Before and after" studies were made by the Road Research Laboratory in 1954 of accidents at thirty road junctions where "Halt" or "Slow" signs had been erected. It was found that injury accidents fell on the average by 80 per cent. and 75 per cent. respectively when "Halt" and "Slow" signs were erected. The Road Research Laboratory reported that neither of these figures was very precise and that no significance should be attached to the difference between them.
