HC Deb 18 February 1981 vol 999 c170W
Mr. Maxwell-Hyslop

asked the Secretary of State for Transport who authorised the painting bright yellow of a metal plate in the road surface across the centre lane of the London-bound carriageway of the M4 just before exit 10 and why; and whether, in view of the fact that drivers take it to be debris obstructing the lane and take violent action to avoid it, he will have it repainted black immediately.

Mr. Kenneth Clarke

I am grateful to my hon. Friend for drawing this to my attention. The metal plate is part of a recording device installed in the carriageway of the M4 motorway by the Department's Transport and Road Research Laboratory.

In view of the difficulties that its yellow colour has caused, the plate has now been painted black.
