prevent the trailer from becoming separated from the motor cycle;
44.2.4.5.4.2.       be securely attached to a substantial portion of the trailer; and
44.2.4.5.4.3.       be equipped with attachments for safety connections. The attachments shall be of sufficient strength to withstand the load imposed and prevent the forward end of the `Drawbar' striking the ground in the event of failure or accidental detachment of the `Coupling' when the towing motor cycle is upright.
44.2.4.5.4.4.       To establish the strength of a trailer 'Drawbar' or 'Coupling' component the following tests should be carried out:

         When attached to a frame representing the trailer frame in its design configuration, the component shall withstand the following loads without incurring loss of attachment or any distortion or failure which would affect the safe towing of a trailer:

         Longitudinal tension and compression - 150% of the 'Gross Trailer Mass';

         Transverse thrust - 50% of the 'Gross Trailer Mass'

         Vertical tension and compression - 50% of the 'Gross Trailer Mass'

44.2.4.5.4.5.       To establish the strength of the attachments provided in association with safety connections, the following tests shall be carried out:

         The safety attachment shall withstand the following failure tests:

         Longitudinal tension – 150% of the 'Gross Trailer Mass'

         Vertical load – 50% of the 'Gross Trailer Mass'

44.2.4.5.4.6.       When viewed in plan, the centre of the trailer `Coupling' shall lie on the longitudinal centreline of the trailer.
44.2.4.5.4.7.       The `Coupling' shall be constructed and fitted in such a manner that accidental disengagement whilst in operation is precluded and when motor cycle and trailer are connected it has sufficient strength to prevent the drawing vehicle and the trailer from becoming separated in service.
44.2.4.5.4.8.       The `Coupling' shall be legibly and indelibly marked with the manufacturer's name or trademark and the maximum 'Gross Trailer Mass' of trailers for which the 'Coupling' body is designed (in kg).  Such markings shall be in characters not less than 5 mm high and shall be located in a prominent position on the 'Coupling' body.

44.2.4.5.5.              Safety Connections for Motor Cycles
44.2.4.5.5.1.       Safety connections shall be capable of supporting a load equal to or greater than the `Gross Trailer Mass'.
44.2.4.5.5.2.       Safety chain shall comply with the Australian Standard referred to in Clause 44.2.4.4.7.2, or other `Approved' standard and be marked accordingly. The capacity of the chain should not be less than the trailer's `Gross Trailer Mass' rating. No welding operation shall be performed on any chain subsequent to its fitment...
44.2.4.5.5.3.       Attachment of safety connections to both `Towbar' and `'Drawbar' shall be separate from the `Coupling' components and their fasteners.
44.2.4.5.5.4.       Safety connections shall be so designed as to prevent the `Drawbar' or attachments interfering with the rotation of the rear wheel.
44.2.5.                          'POLE-TYPE TRAILERS'
