HC Deb 26 October 1955 vol 545 c29W
80. Mr. Arbuthnot

asked the Minister of Transport and Civil Aviation when he now expects to be in a position to make some announcement regarding the use of winking traffic indicators on motor vehicles.

Mr. Boyd-Carpenter

I have now received a Report from the Road Research Laboratory giving the results of their investigations into the respective merits of semaphore arms and flashing indicators on private cars, and I should like to take this opportunity of expressing my gratitude to the Laboratory and to the Medical Research Council with whom they collaborated for this most useful piece of field research. I am at present considering this Report.
