HC Deb 30 October 1985 vol 84 c557W
Mr. Harrison

asked the Secretary of State for Transport if, in the new guidelines for motorway sign cleaning and maintenance, it has been arranged for this to take place at three-yearly intervals; and what additional provisions have been made for the repair or replacement of damaged signs on the most heavily used motorways.

Mr. Ridley

The code of practice for routine maintenance of motorway and all purpose trunk roads (a copy of which is in the Library) specifies that sign faces shall normally be cleaned at three yearly intervals. But the code recognises that some signs may need to be cleaned more frequently than that and there is scope for local variations. The code also requires that motorways should receive safety inspections at seven-day intervals and that these inspections include checks on the general condition of signs.
