MB, MC, MD1, MD2, MD3, NA, NB1, TA and TB vehicles must be provided with 'Wheel Guards' that comply with clause 17.2.4 or clause 17.2.5 below.
17.2.3.                          All wheels of category MD4, ME, NB2, NC, TC and TD vehicles must be provided with 'Wheel Guards' that comply with clause 17.2.5 below.
17.2.4.                          'Wheel Guards' for passenger cars and other light vehicles
17.2.4.1.                    The 'Wheel Guards' (parts of the bodywork, mudguards, etc.) 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.
17.2.4.2.                    When the wheels are in the straight ahead position:
            (a)      in the part formed by radial planes at an angle of 30 degrees to the front and 50 degrees to the rear of the centre of the wheel (see Figure 2), the overall width (q) of the 'Wheel Guards' must be at least sufficient to cover the 'Section Width' (b) of the tyres fitted to the vehicle, taking into account the extremes of tyre/wheel combination as specified by the 'Manufacturer';
            (b)      the rear of the 'Wheel Guards' must not terminate above a horizontal plane 150 mm above the axis of rotation of the wheels (as measured at the wheel centres) and furthermore the intersection of the edge of the 'Wheel Guard' with this plane (point A, Figure 2) must lie outside the median longitudinal plane of the tyre; and
            (c)      within the part formed by the radial planes referred to in part (a) above, the contour and location of the 'Wheel Guards' must satisfy the following requirements:
               (i)        the projection - situated in the vertical plane of the tyre axis - of the depth (p) of the outer edge of the 'Wheel Guards', measured in the vertical longitudinal plane passing through the centre of the tyre, must be at least 30 mm; and
               (ii)      the distance (c) between the lower edges of the 'Wheel Guards' and the axis passing through the centre of the wheels must not exceed 2r, 'r' being the 'Static Loaded Tyre Radius' of the tyre.
17.2.4.2.1.              The depth (p) referred to in part (c)(i) of this clause 17.2.4.2 may be reduced progressively to zero at the radial planes specified in clause 17.2.4.2(a) above.
17.2.4.3.                    In the case of vehicles having adjustable suspension height, the above mentioned requirements must be met when the vehicle is in the normal running position specified by the 'Manufacturer'.

17.2.5.                          'Wheel Guards' for off-road and/or commercial vehicles
17.2.5.1.                    The 'Wheel Guards' must be so designed as to protect other road users, as
