Emission of smoke, vapour, gases, oily substances etc.

74.—(1) Subject to paragraph (7), a vehicle shall be constructed and maintained so as not to emit avoidable smoke or avoidable visible vapour.

(2) A motor vehicle using solid fuel shall be fitted with—

(a)a tray or shield to prevent ashes or cinders from falling onto the road; and

(b)an efficient appliance to prevent any emission of sparks or grit.

(3) Subject to paragraph (7) and to the exemptions specified in an item in column 4 of Table I, wheeled vehicles of a class specified in that item in column 2 shall be constructed so as to comply with the requirements specified in that item in column 3.

(4) A motor vehicle to which an item in Table II applies shall be so constructed as to comply with the requirements relating to conformity of production models set out in the provisions specified in that item in column (4) of that Table.

(5) Instead of complying with paragraph (1) a vehicle may comply with a relevant instrument.

(6) Instead of complying with such provisions of items 1, 2 and 3 in Table I as apply to it, a vehicle may at the time of its first use comply with a relevant instrument.

(7) For the purposes of paragraphs (5) and (6), a reference to a vehicle complying with a relevant instrument is a reference to a vehicle complying—

(a)if it is propelled by a compression ignition engine, with Community Directive 72/306 (or, in the case of an agricultural vehicle, 77/537) or ECE Regulation 24.01, 24.02 or 24.03; or

(b)if it is propelled by a spark ignition engine, with any instrument mentioned in column (4)(a) of Table II.

(8) In relation to a vehicle which—

(a)has an engine the cylinder capacity of which is less than 700 cc and has a rated power speed of more than 3,000 revolutions per minute;

(b)is first used before 1st October 1998,

  • Community Directive 91/542 shall have effect for the purposes of this regulation as if for the figure “0.15” in the Table in paragraph 6.2.1 and 8.3.1.1 there were substituted “0.25”.

  • For the purposes of this paragraph, “rated power speed” has the same meaning as in Community Directive 96/1.

(9) A person shall not use, or cause or permit to be used, on a road a motor vehicle—

(a)from which smoke, visible vapour, grit, sparks, ashes, cinders or oily substance is emitted if that emission causes, or is likely to cause, damage to property or injury or danger to a person who is, or who may reasonably be expected to be, on the road;

(b)which is subject to the requirement in item 2 of Table I (whether or not it is deemed to comply with that requirement by virtue of paragraph (7)) if the fuel injection equipment, the engine speed governor or any other parts of the engine by which it is propelled have been altered or adjusted so as to increase the emission of smoke; or

(c)which is subject to the requirement in item 1 of Table I if the device mentioned in column 2 in that item is used while the vehicle is in motion.

(10) A person shall not use, or cause or permit to be used, on a road a motor vehicle to which item 3 of Table I applies unless it is so maintained that the m eans specified in column 3 of that item are in good working order.

(11) Subject to paragraphs (12), (13) and (14), no person shall use, or cause or permit to be used, on a road a motor vehicle to which an item in Table II applies if, in relation to the emission of the substances specified in column (6) of the item, the vehicle does not comply with the requirements relating to conformity of production models specified in column (4) unless the following conditions are satisifed in respect to it—

(a)the failure to meet those requirements in relation to the emission of those substances does not result from an alteration to the propulsion unit or exhaust system of the vehicle,

(b)neither would those requirements be met in relation to the emission of those substances nor would such emissions be materially reduced if maintenance work of a kind which would fall within the scope of a normal periodic service of the vehicle were to be carried out on the vehicle, and

(c)the failure to meet those requirements in relation to such emissions does not result from any device designed to control the emission of carbon monoxide, hydrocarbons, oxides of nitrogen or particulates fitted to the vehicle being other than in good and efficient working order.

(12) Paragraph (11) shall not apply to a vehicle first used before 26th June 1990.

(13) Where—

(a)a vehicle is fitted with a device of the kind referred to in sub-paragraph (c) of paragraph (11),

(b)the vehicle does not comply with the requirements specified in that paragraph in respect to it, and

(c)the conditions specified in sub-paragraphs (a) and (b) of that paragraph are satisfied in respect to the vehicle, nothing in paragraph (11) shall prevent the vehicle being driven to a place where the device is to be repaired or replaced.

(14) Where a vehicle is constructed or assembled by a person not ordinarily engaged in the business of manufacturing motor vehicles of that description, the date on which it is first used shall, for the purposes of paragraphs (4), (11), (12) and (13), be regarded as being the 1st January immediately preceding the date of manufacture of the engine by which it is propelled.

  • However, the date on which a vehicle is first used shall not, by virtue of the foregoing provisions of this paragraph, be regarded in any circumstances as being later than the date on which it would otherwise have been regarded as being first used had those provisions been omitted.

(15) Without prejudice to paragraphs (1) and (11) and subject to the following provisions of this regulation, no person shall use, or cause or permit to be used on a road, a vehicle first used on or after 1st August 1975 and propelled by a four-stroke spark ignition engine, if the vehicle is in such a condition and running on such fuel that—

(a)when the engine is idling the carbon monoxide content of the exhaust emissions from the engine exceeds—

(i)in the case of a vehicle first used before 1st August 1986, 4.5%; or

(ii)in the case of a vehicle first used on or after 1st August 1986, 3.5%;

of the total exhaust emissions from the engine by volume; and

(b)when the engine is running without load at a rotational speed of 2,000 revolutions per minute, the hydrocarbon content of those emissions exceeds 0.12% of the total exhaust emissions from the engine by volume.

(16) Without prejudice to paragraphs (1) and (11) and subject to the following provisions of this regulation, no person shall use, or cause or permit to be used on a road, a vehicle to which this paragraph applies and which is propelled by a spark ignition engine, if the vehicle is in such a condition and running on such fuel that Part I of Schedule 10 applies to the vehicle.

(i)is first used on or after 1st August 1992 and before 1st August 1994, and

(ii)is of a description mentioned in the Annex to the emissions publication;

(b)a vehicle which—

(ii)is first used on or after 1st August 1994, and

(iii)is of a description mentioned in the Annex to the emissions publication; or

(c)a passenger car which is first used on or after 1st August 1994,

and in this paragraph, “emissions publication” has the meaning given in Part I of Schedule 10.

(a)a vehicle to which paragraph (16) applies; or

(b)a vehicle if, at the date the engine was manufactured, that engine was incapable of meeting the requirements specified in that paragraph.

(19) Paragraph (16) does not apply to a vehicle if, at the date that engine was manufactured, that engine was incapable of meeting the requirements specified in that paragraph.
