HC Deb 24 July 1967 vol 751 c72W
Mr. Anderson

asked the Secretary of State for Wales whether, in view of the recent fatal accident on the M4, he will examine further the case for central crash barriers on the M4 motorway.

Mr. Cledwyn Hughes

There are already central barriers along more than four miles of the M4 in Wales, where the carriageways are at different levels. The types of barrier at present available do not however necessarily increase safety in all the situations which can arise. I am keeping in touch with my right hon. Friend the Minister of Transport, who is carrying out trials with crash barriers, both on selected lengths of motorway and at the Road Research Laboratory, where new designs are being developed.
