| 6.10.2. | When the vehicle is travelling in a straight line, no part of the wheels, other than the tyres, situated above the horizontal plane, passing through their axis of rotation, shall project beyond the vertical projection in a horizontal plane, of the body panel edge above the wheel. However, if functional requirements so warrant, the protective devices which cover wheel nuts and hubs may project beyond the vertical projection of the body panel edge above the wheel, on condition that radius of curvature of the surface of the projection part is not less than 5 mm and that the projection beyond the vertical projection of the body panel edge above the wheel in no case exceeds 30 mm. | a0c0 |
