For the purposes of this item—

• “effective date” means the date of manufacture of the vehicle, except that in the case of a vehicle which for the time being meets the requirements of paragraph 3 of Schedule 1 to these Regulations, it shall mean the 1st of January immediately preceding the date of manufacture of the engine by which it is propelled, if that date is earlier;

• “a normal idling speed” means in the case of a vehicle of a description mentioned in the Annex to the emissions publication, a rotational speed between the minimum and maximum limits shown against that description of vehicle in columns 2(b) and 2(c) respectively of that Annex;

• “the emissions publication” is the publication entitled “In-service Exhaust Emissions Standards for Road Vehicles” (ISBN O-9526457-O-X) published by the Department of Transport;

• “the relevant percentage” means in the case of a vehicle of a description mentioned in the Annex to the emissions publication, the percentage shown against that description of vehicle in column 2(a) of that Annex;

• “rotary piston engine” means an engine in which the torque is provided by means of one or more rotary pistons and not by any reciprocating piston; and any rotary piston engine shall be deemed to be a four-stroke engine;

• “a fast idling speed” means—

  1. (a)

     in the case of a vehicle of a description mentioned in the Annex to the emissions publication, a rotational speed between the minimum and maximum limits shown against that description of vehicle in columns 3(e) and (f) respectively of that Annex; or

  2. (b)

     in any other case, a rotational speed of between 2500 and 3000 revolutions per minute;

• “the lambda value” means the ratio by mass, of air to petrol vapour in the mixture entering the combustion chambers divided by 14.7; and

• “the relevant limits” mean in the case of a vehicle of a description mentioned in the Annex to the emissions publication, the minimum and maximum limits shown against that description of vehicle in columns 3(c) and 3(d) respectively of that Annex.

Paragraphs 2, 3 and 4 shall not apply to—

1. (a)

   vehicles propelled otherwise than by a spark ignition engine;

2. (b)

   vehicles having an effective date before 1st August 1975; and “effective date” means the date of

3. (c)

   vehicles having an effective date before 1st August 1987 and propelled by a rotary piston engine.

Paragraphs 3 and 4(b) shall not apply to vehicles fuelled by natural gas.

Paragraph 4(c) shall not apply to vehicles fuelled by liquid petroleum gas or natural gas.

Paragraphs 2(a) and (b) and 3 shall not apply to vehicles propelled by a 2-stroke engine.

Paragraphs 2(c) and 4 shall not apply to transitional provision vehicles which have been constructed from a kit which—

1. (a)

   included a chassis or a body; and

2. (b)

   was sold by retail before 1st January 1998.

If the vehicle has an effective date on or after 1st August 1979, when the engine by which it is propelled is subject to the free-acceleration test, the coefficient of absorption of the exhaust emissions from the engine immediately after leaving the exhaust shall not exceed—

1. (a)

   if the engine of the vehicle is turbo-charged, 3.0 per metre, or

2. (b)

   in any other case, 2.5 per metre.

For the purposes of this item—

• “effective date” has the same meaning as in item 1;

• “free acceleration” has the same meaning as in Annex II to Directive 77/143/EEC as last amended by Directive 92/55/EEC; and

• “co-efficient of absorption” shall be construed in accordance with paragraph 3.5 of Annex VII to Directive 72/306.

This item shall not apply to vehicles propelled otherwise than by a spark ignition engine.

Paragraph 2 shall not apply to suppression equipment fitted to vehicles which meet the requirements of either paragraph 2 or paragraph 3 of Schedule 1 to these Regulations.

For the purpose of this item—

• “braking device”, “control”, “transmission”, “service braking”, “secondary braking” and “parking braking”, have the same meaning as in 71/320/EEC as last amended by Directive 85/647/EEC;

• “anti-lock device”—

  1. (a)

     except in relation to a vehicle having not more than three wheels, has the same meaning as in 71/320/EEC as last amended by Directive 88/194/EEC; and

  2. (b)

     in relation to a vehicle having not more than three wheels, has the same meaning as in Appendix 2 to the Annex of Directive 93/14/EEC;

• “brake efficiency” means maximum total brake force expressed as a percentage of the maximum gross weight;

• “maximum total brake force” means the total braking force when the brakes are fully applied;

• “total braking force” means the total of the braking forces transmitted by the tyres to the road surface when the brakes are applied;

• “servo-assistance” means an energy supply which supplements the muscular energy of the driver;

• “lateral brake distribution”, in relation to an axle, means the ratio (expressed as a percentage) of the lower to the higher of the braking forces transmitted by the tyres and to the road surface for two wheels, on opposite sides of the vehicle on the same axle;

• “longitudinal brake distribution” means the ratio of the braking forces transmitted by the tyres to the road surface through the front and rear wheels respectively when the vehicle is in running order and being braked on a level surface;

• “in running order” means—

  1. (a)

     with all fluids (such as oils and engine coolant) necessary for the vehicle to be driven, the fuel tanks full, a spare wheel and a tool-kit;

  2. (b)

  3. (c)

     not otherwise carrying any load or passengers.

Paragraphs 1 to 4 shall not apply to vehicles having not more than three wheels, if they comply with the requirements for motor-tricycles in the following provisions of Directive 93/14/EEC—
