HC Deb 17 February 1971 vol 811 c481W
93. Mr. Eadie

asked the Secretary of State for the Environment how long Government Departments have had under active consideration making compulsory the installation of a device to prevent jack-knifing in every articulated lorry.

Mr. Eldon Griffiths

We cannot consider compulsion unless satisfactory equipment is available. The production of this makes its own demands on time and effort. Although development work has taken longer than anyone would wish, there is still a long way to go.
