Additional Provisions Relating to Form of Rear or Side Markings
1. Any variation in a dimension (other than as to the height of a letter) specified in any of the diagrams in Part I shall be treated as permitted for the purposes of these Rules if the variation —
(a)
in the case of a dimension so specified as 250 mm or as over 250 mm, does not exceed 2½% of that dimension;
(b)
in the case of a dimension so specified as 40 mm or as over 40 mm but as under 250 mm, does not exceed 5% of that dimension; or
(c)
in the case of a dimension so specified as under 40 mm, does not exceed 10% of that dimension.
2. Any variation in a dimension as to the height of a letter specified in any of the said diagrams shall be treated as permitted for the purposes of these Rules if the variation —
(a)
in the case of a dimension so specified as 105 mm, does not exceed 2½% of that dimension; or
(b)
in the case of a dimension so specified as 70 mm, does not exceed 5% of that dimension.
3. Any variation in a dimension as to the angle of hatching specified in any of the said diagrams shall be treated as permitted for the purposes of these Rules if the variation does not exceed 5 degrees.
4. Rear and side markings shall be illuminated by the use of red fluorescent material in the shaded areas shown in any of the said diagrams and by the use of yellow reflex reflecting material in any of the areas so shown, being areas not shaded and not constituting a letter.
5. A rear marking as in Diagram 1 or 4 shall be constructed in the form of a single plate, and a rear marking as in Diagram 2, 3 or 5 shall be constructed in the form of two plates of equal size and shape, and such plates shall be legibly and permanently marked with the specification number B.S.

Part III
Provisions As to Position on Vehicle, Maintenance, Etc., of Rear and Side Markings
1. A rear marking shall be fitted at the rear of the vehicle.
2. The lower edge of a rear marking shall be horizontal and at a height of not more than 1700 mm nor less than 400 mm above the ground, whether the vehicle is laden or unladen, and in the case of a rear marking as in Diagram 2, 3 or 5, the lower edge of each half of the marking shall be at the same height above the ground.
3. Every part of a rear marking shall lie within 20 degrees of a transverse vertical plane at right angles to the vertical plane through the longitudinal axis of the vehicle so that —
(a)
in the case of a rear marking as in Diagram 1 or 4, the vertical centre line of the marking lies on that vertical plane through the longitudinal axis of the vehicle; and
(b)
in the case of a rear marking as in Diagram 2, 3 or 5, each half of the marking lies in the same vertical plane and the innermost vertical edges of each half of the marking are equidistant from the vertical plane through the longitudinal axis of the vehicle.
4. A rear marking as in Diagram 2, 3 or 5 shall lie so that each half of the marking is as near as is practicable to the outermost edge of the vehicle on the side thereof on which it is fitted.
5.—(1) A rear marking shall be so fitted that every part thereof is clearly visible at all times when viewed from within a reasonable distance to the rear of the vehicle, except, while the vehicle is being loaded or unloaded, if the vehicle is so constructed at the rear that it is impracticable for the marking to be so fitted, without undue expense or risk of damage to the marking.
[S 450/2005 wef 11/07/2005]
(2) A side marking for a trailer shall be fitted on either side of the trailer as near as practicable to the front end without protruding beyond the trailer.
(3) A side marking shall be so fitted that every part thereof is clearly visible at all times when viewed from within a reasonable distance to the side of the trailer.
[S 450/2005 wef 11/07/2005]
6. The top edge of a side marking shall be at a height of not more than 1,700 mm nor less than 800 mm above the ground whether the vehicle is laden or unladen and shall stay within a plane parallel to the top level of the trailer.
7. Rear and side markings shall be securely attached to the vehicle so that no part of the markings projects beyond the outermost part of the vehicle on either side.
8. Rear and side markings shall be maintained in a clean and efficient condition while the vehicle is on a road.
