§ Mr. Peter Walkerasked the Minister of Transport if she will publish further details of table 5 of the preliminary analysis by the Road Research Laboratory on the 70 miles per hour speed limit experiment, showing how many accidents were due to mechanical failures, worn tyres, and drink, respectively, how many occurred through a vehicle passing on the inside, how many occurred when vehicles 291W were bunching, how many had occurred when one or more of the vehicles involved was exceeding 70 miles per hour, and how many had occurred at a time when wet conditions were causing vehicle spray; and if she will indicate any difference in police patrol car activity by giving for each of the December-April periods over the six years the number of police patrol car hours on the 73 miles of the London-Birmingham motorway.
§ Mr. John MorrisIt is impracticable to cover these matters in the Laboratory's assessment of the first four months of the experiment which is to be published in July. Details of this sort will, however, be included, as far as possible, in the Road Research Laboratory report, which will be published in 1967 before the end of the 70 miles per hour speed limit experiment. The information regarding police patrol car activity over the last six years is not available.
