HC Deb 28 April 1971 vol 816 c132W
111. Mr. Dykes

asked the Secretary of State for the Environment what recent examination of road lane moving procedures in other countries has been made by his Department with a view to possible improvements in the United Kingdom.

Mr. Eldon Griffiths

Safe procedures for lane changing are set out in the Highway Code and my Department's manual "Driving". The Road Research Laboratory are also studying overtaking behaviour in association with research workers in other countries.
