1.                               for any point in the width of the vehicle which is within one metre fore and aft of any 'Axle', 100 mm;
 2.                               for the mid-point between any 2 consecutive 'Axles', the dimension in millimetres obtained by multiplying the distance between those 2 'Axles' in metres by 33.33; and
 3.                               for any other point, 'Ground Clearance' is such that if the wheels of one 'Axle' are on one plane and the wheels on the next consecutive 'Axle' are on another plane which intersects the first so that the angle between them is 7 degrees 38 minutes the point will pass over the apex transverse to the vehicle formed by that intersection, as shown in Figure 1.
 1.                                      'Overall Width', including any 'Equipment'
     1.                               The 'Overall Width' of any motor vehicle (other than an L-Group vehicle) or trailer must not exceed 2,500 mm.
     2.                               The 'Overall Width' of an L-Group vehicle must be as follows:
         1.                         In the case of a two wheel vehicle (LA or LC), the maximum width must not exceed 1,000 mm.
         2.                         In the case of a three wheel vehicle (LB or LE) or a motor cycle with a side car (LD), the maximum width must not exceed 1,850 mm.
 1.                                           AXLE CONFIGURATION
     1.                                     Vehicles must satisfy the following requirements:
     2.                                     A rigid motor vehicle must be supported by 2 'Axle Groups' disposed as follows:
         1.                               one towards the front of the vehicle, with all wheels connected to the steering system for that part of the vehicle, on either a 'Single Axle' or a 'Twin Steer Axle Group'; and
         2.                               one towards the rear of the vehicle.
     3.                                     A 'Semi-trailer' must be supported towards the rear by an 'Axle Group'.
         1.                               Every 'Semi-trailer' which is extendible or fitted with a sliding 'Axle Group' must be so constructed that:
             1.                         positive locking devices are utilised;
             2.                         all locking device controls must be in a lockable   enclosure when mounted on the chassis;
             3.                         failure of the engagement of the locking device   must activate a visible and/or audible warning device;
             4.                         where the locking device is air operated the supply must be fitted with a protection valve to prevent loss of air to the air brake supply in the event of line fracture or failure; and
             5.                         the movable assembly must be fitted with substantial stops to prevent disconnection from the vehicle in the event of failure of the locking device.
     4.                                     A trailer other than a 'Semi-trailer' must be supported by either:
         1.                               one 'Axle Group'; or
         2.                               an 'Axle Group' towards both the front and rear of the trailer provided that all wheels in the front 'Axle Group' are connected to the steering mechanism for that part
