HC Deb 16 January 1986 vol 89 c631W
Mr. Harrison

asked the Secretary of State for Transport what sources of information he uses in replying to parliamentary questions on the state of road signs on motorways; and what checks his Department carries out to confirm the information provided.

Mr. Ridley

Details are obtained from the county councils which maintain the motorways as my agents. My Department's regional offices also periodically carry out their own inspections of motorways.
