HC Deb 16 February 1981 vol 999 cc57-8W
Mr. Pawsey

asked the Secretary of State for Transport if he is satisfied that the requirements relating to the rear lights of heavy goods vehicles are such as to ensure that such vehicles are safely visible by other road users when after rain the lights may be obscured by road dirt.

Mr. Kenneth Clarke

Yes, if they are properly observed. The law requires the obligatory lamps and reflectors on all vehicles, including heavy goods vehicles, to be kept in a clean condition and in good and efficient working order at all times. The compulsory red and yellow rear markings on heavy goods vehicles, which are intended to improve their conspicuity to following traffic, are subject to similar requirements.
