§ Mr. Aspinwall
asked the Minister of Transport if he will study the feasibility of changing the method by which roads are marked to show parking restrictions so that single and broken single yellow lines only are used; and what estimate he can make of the savings in labour and materials which would result.
§ Mr. Kenneth Clarke
The possibility of changing the system to reduce marking requirements has been thoroughly examined and found acceptable in principle. The problem is that any conversion should be country-wide and rapidly effected because parallel operation of different systems could present difficulties of enforcement. This would involve heavy short-term costs to achieve long-term savings. These costs cannot be accurately estimated as the total extent of existing yellow lines in unknown. A sample survey indicates, however, that the works costs alone would be too great to be contemplated at present.
