HC Deb 04 October 1939 vol 351 c1937
37. Mr. Leonard

asked the Minister of Transport whether he has considered the desirability of issuing regulations prohibiting the use of all signs on motor vehicles claiming priority; and will he take steps to substitute an easily recognisable official sign within his control for issue to departments requiring them?

Captain Wallace

It has, I believe, become generally recognised that these signs confer no privilege or priority on the road and I do not think that it will be necessary for me to make regulations in regard to them.
