(a)a standard or code of practice of a national standards body or equivalent body of any EEA State;

(b)any international standard recognised for use as a standard by any EEA State; or

(c)a technical specification or code of practice which, whether mandatory or not, is recognised for use as a standardby a public authority of any EEA State,

where the standard, code of practice, international standard or technical specification provides, in relation to couplings, a level of safety and compatibility with a BS coupling of the type shown in figure 1 of the British Standard specification equivalent to that provided by the British Standard specification as modified in accordance with paragraph (6).

(8) Paragraph (7) shall have effect—

(a)in relation to paragraph (4), as if for the words “paragraph (3)” there were substituted the words “paragraph (4)” and for the words “figure 1” there were substituted the words “figure 4”; and

(3) The condition is fulfilled while the vehicle is completing a journey at the beginning of which the ABS was operating correctly or is being driven to a place where the ABS is to undergo repairs.

(4) Paragraph (5) applies to every wheeled motor vehicle except—

(a)an agricultural motor vehicle which is not driven at more than 20 mph;

(b)a works truck;

(c)a pedestrian-controlled vehicle; and

(d)an industrial tractor.

(5) A vehicle to which this paragraph applies and which is of a class specified in an item in column 2 of Table I shall, subject to any exemption shown for that item in column 4, be so maintained that—

(a)its service braking system has a total braking efficiency not less than that shown in column 3(a) for that item; and

(b)if the vehicle is a heavy motor car, a motor car first used on or after 1st January 1915 or a motor cycle first used on or after 1st January 1927,

its secondary braking system has a total braking efficiency not less than that shown in column 3(b) for those items.

(6) A goods vehicle shall not be deemed to comply with the requirements of paragraph (5) unless it is capable of complying with those requirements both at the laden weight at which it is operating at any time and when its laden weight is equal to the design gross weight of the vehicle.

  • Provided that in the case of a goods vehicle drawing a trailer, references in this paragraph to laden weight refer to the combined laden weight of the drawing vehicle and the trailer and references to gross weight and design gross weight are to be taken as references to train weight and design train weight respectively.

(7) A bus shall be deemed not to comply with the requirements of paragraph (5) unless it is capable of complying with those requirements both at its laden weight for the time being and at its relevant weight.

(8) For the purposes of paragraph (7), the relevant weight—

(a)in relation to a bus first used on or after lst April 1982, is its maximum gross weight; and

(b)in relation to a bus first used before that date, is the weight specified in paragraph (9).

(9) The weight referred to in paragraph (8)(b) is—

where—

  • X is the unladen weight of that bus in kilograms;

  • Y is the number of passengers that the bus is constructed or adapted to carry seated in addition to the driver; and

  • Z is—

    (a)

    in the case of a PSV which is not an articulated bus and has a standing capacity exceeding 8 persons, the standing capacity minus 8;

    (b)

    in the case of a PSV which is an articulated bus, the standing capacity; or

    (c)

    in any other case, nil.

(10) The brakes of an agricultural motor vehicle which is first used on or after 1st June 1986 and is not driven at more than 20 mph, and of every agricultural trailer manufactured on or after 1st December 1985 shall be capable of achieving a braking efficiency of not less than 25% when the weight of the vehicle is equal to the total maximum axle weights which the vehicle is designed to have.

(11) A class of vehicle or combination of vehicles specified in an item in column 2 of Table II shall be so maintained that its brakes are capable, without the assistance of stored energy, of holding it stationary on a gradient of at least the percentage specified in column 3 in that item.

Application of brakes of trailers

25.—(1) Subject to paragraph (2) where a trailer is drawn by a motor vehicle the driver (or in the case of a locomotive one of the persons employed in driving or tending the locomotive) shall be in a position readily to operate any brakes required by these Regulations to be fitted to the trailer as well as the brakes of the motor vehicle unless a person other than the driver (or in the case of a locomotive a person other than one of the persons employed in driving or tending the locomotive) is in a position and competent efficiently to apply the brakes of the trailer.

(2) This regulation shall not apply to a trailer which—
