HC Deb 11 December 1958 vol 597 c97W
56. Mr. Russell

asked the Secretary of State for the Home Department how many prosecutions or warnings have been given in the Metropolitan Police district in recent months for the emission of smoke from vehicles with diesel engines; and if he will arrange for such offences to be recorded separately in the Return of Offences Relating to Motor Vehicles.

Mr. Renton

During the twelve months ended 30th September, 1958, 73 persons were prosecuted and 77 persons received written warnings for offences committed in the Metropolitan Police District against the Regulation which makes it an offence in certain circumstances to use a motor vehicle which emits smoke. I regret that no separate figures are available relating to vehicles with diesel engines. Much additional work would he required if these offences were to be recorded separately in the Return of Offences Relating to Motor Vehicles, and my right hon. Friend does not think this would be justified.
