HC Deb 17 June 1931 vol 253 c1736
42. Sir GEORGE PENNY

asked the Minister of Transport whether he will issue regulations making compulsory the use of mechanical and illuminated signalling arms on heavy mercantile and passenger-carrying vehicles?

Mr. HERBERT MORRISON

The Highway Code describes fully the hand signals that drivers should give when intending to stop, slow down or change direction, while stating at the same time that where the appropriate signal can be given effectively by a suitable mechanical or electrical device there is no objection to its use. I do not think I should be at present justified in making the use of such mechanical or electrical devices compulsory in the case of any particular class or description of vehicle.
