With effect from 1 October 1985, Member States : — may no longer issue the document referred to in the last indent of Article 10 (1) of Directive 70/156/EEC in respect of a type of motor vehicle of which the sound level and exhaust system do not comply with the provisions of Directive 70/157/EEC, as amended by this Directive,
