HC Deb 17 February 1971 vol 811 c475W
112. Mr. Ronald Bell

asked the Secretary of State for the Environment whether he will take steps to discourage the present excessive use of two-tone horns by vehicles in the public service.

Mr. Eldon Griffiths

The regulations allow emergency service vehicles to use two-tone horns when it is necessary to do so as a warning to other road users. The precise circumstances in which they should be used must be left to the good sense of those concerned.
