HC Deb 01 March 1968 vol 759 cc437-8W
Mr. Arnold Shaw

asked the Minister of Transport whether she will seek to amend the law to deal, in particular, with the excessive emission of exhaust fumes from the sides of vehicles, particularly from diesel vehicles.

Mr. Carmichael

It is already unlawful for a vehicle to discharge excessive smoke or vapour. In 1965 and 1966 there were respectively 2,800 and 2,140 prosecutions by the police and about 13,000 and 7,000 prohibitions of use issued by Ministry of Transport Vehicle Examiners.
