(iii) domed heads of bolts or rivets may protrude beyond the surface to a distance not exceeding 10 mm;

(b)no part of the lowest edge of a sideguard shall be more than 550 mm above the ground when the vehicle to which it is fitted is on level ground and, in the case of a semi-trailer, when its load platform is horizontal;

(c)in a case specified in an item in column 2 of the Table the highest edge of a sideguard shall be as specified in that item in column 3;

(f)the foremost edge of a sideguard fitted to a semi-trailer with landing legs shall, as well as complying with sub-paragraph (e), not be more than 250 mm to the rear of a transverse plane passing through the centre of the leg nearest to that edge;

(g)the distance between the foremost edge of a sideguard fitted to a vehicle other than a semi-trailer and a transverse plane passing through the rearmost part of the tyre fitted to the wheel of the vehicle nearest to it shall not exceed 300 mm if the vehicle is a motor vehicle and 500 mm if the vehicle is a trailer;

(h)the external edges of a sideguard shall be rounded at a radius of at least 2.5 mm;

(i)no sideguard shall be more than 30 mm inboard from the tangential plane;

(j)no sideguard shall project beyond the longitudinal plane from which, in the absence of a sideguard, the vehicle's overall width would fall to be measured;

(k)every sideguard shall cover an area extending to at least 100 mm upwards from its lowest edge 100 mm downwards from its highest edge, and 100 mm rearwards and inwards from its foremost edge, and no sideguard shall have a vertical gap measuring more than 300 mm nor any vertical surface measuring less than 100 mm; and

(l)except in the case of a vehicle described in paragraph (1) (c) every sideguard shall be capable of withstanding a force of 2 kilonewtons applied perpendicularly to any part of its surface by the centre of a ram the face of which is circular and not more than 220 mm in diameter, and during such application—

(8) In this regulation

relevant plate” means a Ministry plate, where fitted, and in other cases a plate fitted in accordance with regulation 66;

relevant train weight” means the train weight shown in column 2 of the Ministry plate, where fitted, and in other cases the maximum train weight shown at item 8 of the plate fitted in accordance with regulation 66; and

tangential plane”, in relation to a sideguard, means the vertical plane tangential to the external face of the outermost part of the tyre (excluding any distortion caused by the weight of the vehicle) fitted to the outermost wheel at the rear and on the same side of the vehicle.
