HC Deb 28 April 1971 vol 816 c130W
62. Mr. Dykes

asked the Secretary of State for the Environment whether he will examine the flashing amber light method of junction control of traffic in evening hours, as practised on the Continent, with a view to its possible introduction in Great Britain.

Mr. Griffiths

No. Continental signals are generally fixed-time; ours are vehicle-actuated and cause less delay at off peak times.
