'Livestock Trailer' must not exceed 4.6 metres.
     5.                               'Ground Clearance'
         1.                         The 'Ground Clearance' of a trailer, measured from a horizontal road surface to any point on the underside of the vehicle except the tyres, wheels and wheel hubs must, under the conditions of 'Maximum Loaded Test Mass' loading as specified in the relevant braking rule, be not less than:
             1.                   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
             2.                   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.
     6.                               'Overall Width', including any 'Equipment'
         1.                         The 'Overall Width' of any trailer must not exceed 2,500 mm.
     7.                               'Running Clearance'
         1.                         The 'Running Clearance' of a trailer must be not less than 100 mm.
 1.                                           AXLE CONFIGURATION
     1.                                     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.
     2.                                     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.
     3.                                     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 of the vehicle.
 2.                                           LOAD SHARING SUSPENSION
     1.                                     All the 'Axles' in an 'Axle Group', other than a 'Twin Steer Axle Group' with
