17.2.5.1.                    The 'Wheel Guards' must be so designed as to protect other road users, as far as practicable, against thrown-up stones, mud, ice, snow and water and to reduce for those users the dangers due to contact with the moving wheels.
17.2.5.2.                    The 'Wheel Guards' on the rearmost wheels must provide continuous protection between a point in area A and a point in area B in Figure 3, and must be provided for the 'Overall Tyre Width' (excluding the deflected part of the tyre sidewall, between the lowest point of the 'Tyre Rim' and the ground) of all tyres.
17.2.5.2.1.              In the case of steerable wheels, the requirements of this clause 17.2.5.2 shall only apply when the wheels are in the straight-ahead position.
17.2.5.3.                    'Wheel Guards' may consist of either permanent body structure or part structure and other components, including mudflaps, provided the specified protection is retained during vehicle operation.
17.2.5.4.                    Where two (2) or more 'Axles' form an 'Axle Group', separate 'Wheel Guards' may be provided for each rear wheel or a single 'Wheel Guard' may be provided which provides continuous protection from area 'A' of the foremost wheel to area 'B' of the rearmost wheel in Figure 3.

Except when 'Rear Marking Plates' are fitted, for every rear 'Wheel Guard' affixed to a motor vehicle, or trailer which is 2.2 metres or more in 'Overall Width' and which has a body of the tray type, that portion of the external surface of such 'Wheel Guard' which is visible to the rear of such vehicle must be white or silver in colour and clearly visible.
