HC Deb 22 October 1975 vol 898 c176W
Mr. Roy Hughes

asked the Secretary of State for the Environment at how many sites in the country, in conjunction with local authorities, his Department has agreed to install experimental ramp speed retarders.

Mr. Carmichael

We expect to instal experimental humps at about eight sites in all. Two have so far been agreed with the local authorities concerned, subject to the consideration of objections.
