§ Mr. Iain Millsasked the Minister of Transport how many car accidents involving death, injury or serious damage have occurred in which tyres were the primary or contributory factor.
§ Mr. Kenneth ClarkeRoutine identification of primary or contributory causes of accidents is not possible on a national basis.
However, of 2,000 accidents investigated " on the spot ", in the area around the Transport and Road Research Laboratory in the period 1970 to 1974, tyre defects were judged to be a main contributory factor in under 3 per cent. of the cases.
