HC Deb 11 July 1985 vol 82 cc486-7W
Mr. Alexander

asked the Secretary of State for Transport if he will consider seeking to require coloured lines to be painted in the middle of roads in built-up areas in order to indicate to drivers that they are driving in built-up areas, during hours of darkness.

Mrs. Chalker

No. Coloured lines would be less conspicuous than the present white ones and differentiation between colours would be very difficult, especially with the lighting systems in current use.
