The Road Vehicles (Construction and Use) Regulations 1986

Marking of longer projections

3.—(a) Every forward and rearward projection to which this paragraph applies shall be fitted with—

(i) an end marker, except in the case of a rearward projection which is fitted with a rear marking in accordance with the Lighting Regulations, and

(ii) where required by sub-paragraphs (c) and (d) of this paragraph, two or more side markers;

which shall be of the size, shape and colour described in Part II of this Schedule.

(b) the end marker shall be so fitted that—

(i) it is as near as is practicable in a transverse plane,

(ii) it is not more than 0.5 m from the extreme end of the projection,

(iii) the vertical distance between the lowest point of the marker and the road surface is not more than 2.5 m,

(iv) it, and any means by which it is fitted to the projection, impedes the view of the driver as little as possible, and

(v) it is clearly visible within a reasonable distance to a person using the road at the end of the vehicle from which the projection extends;

(c) where the forward projection exceeds 2 m or the rearward projection exceeds 3 m, one side marker shall be fitted on the right hand side and one on the left hand side of the projection so that—

(i) each marker is as near as is practicable in a longitudinal plane,

(ii) no part extends beyond the end of the projection,

(iii) the vertical distance between the lowest part of each marker and the surface of the road is not more than 2.5 m,

(iv) the horizontal distance between each marker and the end marker or, as the case may be, the rear marking carried in accordance with the Lighting Regulations does not exceed 1 m, and

(v) each marker is clearly visible within a reasonable distance to a person using the road on that side of the projection;

(d) where—

(i) a forward projection exceeds 4.5 m, or

(ii) a rearward projection exceeds 5 m

extra side markers shall be fitted on either side of the projection so that the horizontal distance between the extreme projecting point of the vehicle from which the projection extends and the nearest point on any side marker from that point, and between the nearest points of any adjacent side markers on the same side does not exceed—

• 2.5 m in the case of a forward projection, or

• 3.5 m in the case of a rearward projection.

For the purposes of this sub-paragraph the expression “the vehicle” shall not include any special appliance or apparatus or any part thereof which is a forward projection or a rearward projection within the meaning of regulation 81;

(e) the extra side markers required by this sub-paragraph shall also meet the requirements of (i), (iii) and (v) of sub-paragraph (c);

(f) every marker fitted in accordance with this paragraph shall be kept clean and unobscured and during the hours of darkness be illuminated by a lamp which renders it readily visible from a reasonable distance and which is so shielded that its light, except as reflected from the marker, is not visible to other persons using the road.
