HC Deb 21 July 1969 vol 787 cc258-9W
Rear-Admiral Morgan-Giles

asked the Minister of Transport to what extent it is his policy to impose 40 miles per hour speed limits only in those areas where it is estimated that this speed will be voluntarily observed.

Mr. Marsh

If speed limits are not seen to be reasonable and so voluntarily observed by the great majority of drivers, they cannot be made effective by police action. Such limits do little if anything to reduce accidents and have a damaging effect on speed limits generally.
