asked the Minister of War Transport what instructions have been issued for the limitation of white lines to main roads; and if he will consider issuing special instructions to local authorities in districts where fogs are known to be frequent to relax the ruling.

No such limiting instructions have been issued. I have endorsed the recommendation of the Departmental Committee on Traffic Signs. 1933, that it is advantageous, especially in areas subject to fog, to paint white lines across road junctions in continuation of the kerbs as a guide to traffic.
