HC Deb 15 July 1942 vol 381 c1214
23. Captain Gammans

asked the Parliamentary Secretary to the Ministry of War Transport whether in view of the reduction in road traffic, he is prepared to cut down the number of traffic lights at less important crossings, in order to save electric power?

Sir A. Salter

Arrangements have already been made for a review of all road traffic light signal installations, to determine what reductions can be made.
