This proposal for a Directive seeks to limit the noise generated by the contact between types in motion and road surfaces. In conjunction with the action already taken in order to curtail noise emissions from the mechanical part of the vehicles, the new measures will help to reduce noise emissions caused by road traffic, without thereby diminishing road safety and without unduly dusrupting the tyre market. The proposal is a follow-up to the provisions of Article 4(2) of Directive 92/97/EEC amending Directive 70/157/EEC relating to the permissible sound level and the exhaust system of motor vehicles. The Council's common position involves no changes of substance to the Commission's initial proposal, except as regards Article 3. Since the Council has adopted the common position unanimously, the Commission can at this stage only take note of the common position.�
