asked the Secretary of State for Transport, in view of the need to decrease accidents, if he will study the 12-month experiment of edge lining on rural unlit roads by the East Sussex County Council and the remarkable decrease in accidents; and if he will make a statement.

Interim data from the trial in East Sussex has been studied and results are encouraging. I have agreed to look at the two-year results when they become available, and these, taken together with reports from highway authorities, will be studied to see whether there is any need to revise present design policies under which a good deal of edge lining has already been carried out.
