89. Mr. Jenningsasked the Parliamentary Secretary to the Ministry of Works, as representing the Lord President of the Council, how far the investigations conducted by the Road Research Laboratory into the wearing of crash helmets by motor cyclists denote their efficacy.
§ Mr. H. NichollsA study by the Road Research Laboratory, with the co-operation of the Metropolitan Police, of 7,000 accidents in 1954 and 1955 showed that the wearing of a crash helmet appeared to reduce the risk of death by about 40 per cent. It also reduced by 30 per cent. to 40 per cent. the chance of injury to that part of the head covered by the helmet.
