§ Mr. MillsTo ask the Secretary of State for Transport what plans he has to introduce type approval standards for the approval of noise levels produced by motorway road surfaces; and if he will make a statement.
§ Mr. KeyType approval standards are not appropriate for the noise levels arising from road surfaces. The Department provides a specification setting limits on the surface texture, which seeks to minimise the level of noise from traffic consistent with safety requirements for adequate skidding resistance.
