7.—(1) This paragraph applies where—
(a)any relevant vehicle is carrying a load; and
(b)the load has a lateral projection or projections on either side exceeding 305 millimetres in length.
(2) Side markers must be fitted to the lateral projection so that, in respect of each side of the vehicle from which the projection extends, one marker is visible from the front of the vehicle and one marker is visible from the rear of the vehicle.
(3) Each side marker must be fitted so that at least part of it is within 50 millimetres of a longitudinal plane passing through the point on that side of the projection which is furthest from the axis of the vehicle.
8.—(1) If the user of the vehicle shows that it is not reasonably practicable to fit side markers in accordance with paragraph 7, the load must be marked with tape so that the point at which the width of the load is at its greatest is clearly visible from the front, rear and side of the vehicle.
(2) The tape must be—
(a)red, yellow or white (or any combination); and
(b)made of day-glow, fluorescent or retro-reflective material which is of a standard approved by—
(i)the British Standards Institution; or
(ii)an equivalent body in another EEA State or in any other country which is a member of the United Nations Economic Commission for Europe.
(3) Nothing in this paragraph affects any requirement imposed by the Lighting Regulations, including, in particular, the requirements of regulation 11(1) (which states that no retro-reflective material is to be fitted to a vehicle which is capable of showing red light to the front of the vehicle) and regulation 11(2) (which states that no retro-reflective material is to be fitted to a vehicle which is capable of showing any light other than red to the rear).
