§ 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.
