HC Deb 19 January 1987 vol 108 cc387-8W
Sir John Farr

asked the Secretary of State for Transport if he will install on the M1 at its junction with the M6 Marconi MET-3 fog detectors for a period of evaluation.

Mr. Peter Bottomley

There are no present plans to install fog detection equipment on the M1 motorway. As announced on 29 October, trials of differing designs of equipment will be carried out elsewhere over this winter and next winter to decide which design best meets the Department's requirements. The new system will then be installed at the 30 fog-prone sites on the M25 identified by the Metrological Office. The work is due for completion in 1990. The effectiveness of the system will be monitored to determine whether it should be used on other motorways.
