HC Deb 27 July 1961 vol 645 cc76-7W
60. Sir B. Janner

asked the Secretary of State for the Home Department what standard of silence is imposed on the motor cycles used by the Metropolitan Police Force.

Mr. R. A. Butler

The Commissioner of Police does all he can to ensure that motor cycles used by the Metropolitan Police do not make undue noise, particularly at night. A considerable reduction in the sound made by the heavier machines was effected some time ago by arranging for the manufacturers to deliver new machines with an additional baffle in the tail pipe of the exhaust.
