(b)if the vehicle in question is first used on or after 1st April 1991, but before 1st February 1996, the silencer must be so constructed that, were it to be fitted to an unused vehicle of the same model as the vehicle in question, the unused vehicle would meet—

(i)the requirements of item 3 of the Table in Part I of Schedule 9; and

(ii)the requirements specified in paragraph 3 (other than sub-paragraphs 3.2 and 3.3) of Annex I to Community Directive 78/1015 or 89/235;

and the silencer must be marked in accordance with sub-paragraph 3.3 of that Annex;

(c)if the vehicle in question is first used on or after 1st February 1996, the silencer must be so constructed that, were it to be fitted to an unused vehicle of the same model as the vehicle in question, the unused vehicle would meet—

(8) For the purposes of this regulation, Community Directive 89/235 shall have effect as if—

(a)in Annex I, for sub-paragraph 3.4.1, there were substituted—

3.4.1.After removal of the fibrous material, the vehicle must meet the relevant requirements.; and

(9) For the purposes of paragraphs (1)(b) and (2) in their application to vehicles with a design speed not exceeding 50 km/h, Community Directive 89/235 EEC shall have effect as if it were not only modified in accordance with paragraph (8) but were further modified by the omission of—

(a)fitted to a vehicle before 1st February 1997; and

(b)clearly and indelibly marked with the name or trade mark of the manufacturer of the silencer and with that manufacturer’s part number relating to it,

paragraphs (5) and (6) of this regulation and Parts II and III of Schedule 9 shall have effect as if they contained no reference to a silencer being marked.

(11) For the purposes of this regulation, a silencer forming part of the exhaust system of a vehicle shall not be regarded as being marked in accordance with sub-paragraph 3.3 of Annex I to Community Directive 78/1015 or 89/235, paragraph (10) of this regulation or any paragraph of Part II of Schedule 9 if the marking is so obscured by any part of the vehicle that it cannot easily be read.

(12) Part III of Schedule 9 shall have effect for the purpose of exempting certain silencers from the provisions of paragraph (4).

(13) No person shall use a motor cycle on a road or cause or permit such a vehicle to be so used if any part of the exhaust system has been indelibly marked by the manufacturer of that part with the words “NOT FOR ROAD USE” or words to that effect.

(14) In this regulation—

“original silencer”, in relation to a vehicle, means a silencer which was fitted to the vehicle when it was manufactured;

“replacement silencer”, in relation to a vehicle, means a silencer fitted to the vehicle, not being an original silencer; and

“trade mark” has the same meaning as in the Trade Marks Act 1994(1).
