§ LORD CHESHAMasked Her Majesty's Government:
How many accidents on motorways and on the roads not subject to speed limits during 1960, 1961, 1962, 1963 and 1964 involved vehicles travelling at speeds in excess of 70 m.p.h.; and, of these, how many resulted in fatal or serious injury.
§ THE PARLIAMENTARY SECRETARY, MINISTRY OF POWER (LORD LINDGREN)We do not know. We do, however, know that the injury accident rate on American expressways, where maximum speed limits generally apply, compare favourably with those in Europe, where general speed limits are exceptional. There is also evidence from America that the casualty rate is about three times higher at speeds over 70 m.p.h. than at speeds between 65 and 70 m.p.h.
House adjourned at fourteen minutes past six o'clock.
