The preparation of the detailed information asked for in this question would entail the diversion of staff, both in the police forces and in the Ministry of Transport, from more urgent work, to an extent which I should not feel justified in accepting in present circumstances. I am aware that there have been complaints in regard to the speed of public service vehicles, and I have taken steps to assure myself that operators are not working to speeds which are unsafe under black-out conditions. If, however, the hon. Member has in mind any particular case where it is alleged that these conditions are not being observed, I shall be glad to make inquiries if he will send me the necessary particulars. With regard to commercial good vehicles, there has been no modification of the statutory speed limits except in the case of vehicles used by the armed Forces. In reply to the last part of the question, it is the present policy that an all-red period for pedestrians at traffic lights should be provided where the volume of pedestrian traffic justifies it and where it is practicable to hold up traffic simultaneously on all the roads forming the intersection.
