HC Deb 12 March 1925 vol 181 cc1498-9
109. Sir H. BRITTAIN

asked the Minister of Transport to extent the white dividing line in the centre of roads for the purpose of guiding motor and other traffic is being made use of; how many local authorities have already adopted it; whether it has the approval of the Ministry; and whether any material has yet been discovered which is impervious to rain?

The MINISTER of TRANSPORT (Colonel Ashley)

Isolated experiments have been made in many parts of the country, but I have no exact information regarding the number of local authorities who have adopted the practice. I am inclined to think that, in certain circumstances, the use of the white dividing line tends to facilitate the flow of traffic and to diminish the risk of accident. I am of opinion, however, that the greatest care should be exercised to limit the use of these signs, as their indiscriminate use will only defeat the object in view. I am informed that experiments are now being carried out with lines consisting of white stone setts, but I understand that the results on the road surface have not been altogether satisfactory.
