asked the Secretary of State for the Environment why recent trunk road improvements have included the provision of a nearside margin of carriageway some 2 ft. wide separated by a white line; and whether he will revise the Highway Code so that advice is given as to whether this margin should or should not be used by motorists to facilitate over-taking by other vehicles, and as to whether it should or should not be used in any circumstances by cyclists.

A hard strip, usually about 3 ft. wide, is added to the carriageway of certain roads in order to reduce the effect on traffic flow of stationary vehicles. My right hon. Friend will consider whether the Highway Code should contain advice about its use.
