HC Deb 14 July 1966 vol 731 c246W
89. Mr. Ronald Bell

asked the Secretary of State for the Home Department what persons are authorised by regulations to use two-tone horns; and whether he will take the necessary steps to prevent the use of such horns.

Mr. Roy Jenkins

Two-tone horns may be used only for the purposes of certain emergency services such as police, fire and ambulance.

The enforcement of the regulations is a matter for chief officers of police.
