strength of the attachments provided on the 'Towbar' for safety connections, the following tests shall be carried out:

         The safety attachments shall withstand the following loads without failure:

           Longitudinal tension – The 'Towbar's' specified towing capacity.

           Vertical load - 0.5 x the 'Towbar's' specified towing capacity.

44.2.4.4.4.4.       The 'Towbar' shall clearly and permanently display the following information when fitted to the vehicle:
44.2.4.4.4.4.1.      the 'Towbar' manufacturer's name or trade marl
44.2.4.4.4.4.2.      the 'make and model' shown on the 'Compliance Plate' fitted to the vehicle to which it is designed or manufacturer's part number, and
44.2.4.4.4.4.3.      the towing capacity expressed in kg. The towing capacity shall be the `Gross Trailer Mass' for which the `Towbar' is designed.
44.2.4.4.4.5.       A Towbar' bearing reference to manufacture for a particular 'make and model' shall be fitted only to a vehicle of that make and model classification, or any subsequent model variant, provided that the 'Towbar' attachment points remain unchanged.
44.2.4.4.4.6.       The towing capacity of a `Towbar' fitted to a vehicle as displayed on the 'Towbar' shall not exceed 1.5 times the 'Unladen Mass' for an MA vehicle or the 'Unladen Mass' for an MB or MC vehicle, or the manufacturer's recommended towing capacity, whichever is the least
44.2.4.4.5.              'Drawbars' for passenger cars (MA, MB, MC)

         The 'Drawbar' shall:

44.2.4.4.5.1.       be of sufficient strength to prevent the trailer from becoming separated from the 'Coupling'
44.2.4.4.5.2.       be securely attached to a substantial portion of the trailer, and
44.2.4.4.5.3.       be equipped with attachments for safety connections. The attachments shall be of sufficient strength to withstand the loads imposed and prevent the front end of the 'Drawbar' striking the ground in the event of failure or accidental detachment of the `Coupling'.
44.2.4.4.5.4.       To establish the strength of a `Drawbar' the following tests should be carried out: When attached to a frame representing the trailer frame in its design configuration, the `Drawbar' shall withstand the following loads without incurring loss of attachment or any distortion or failure which would affect the safe towing of the trailer:

         Longitudinal tension and compression – 1.5 x the 'Gross Trailer Mass'

         Transverse thrust – 0.5 x the `Gross Trailer Mass'.

         Vertical tension and compression – 0.5 x the 'Gross Trailer Mass'.

44.2.4.4.5.5.       To establish the strength of attachments provided on the 'Drawbar' for safety connections, the following tests should be carried out:

         The safety attachments shall withstand the following loads without failure:

           Longitudinal tension - The 'Gross Trailer Mass'.

           Vertical load – 0.5 x the `Gross Trailer Mass'.

44.2.4.4.6.              Not used
44.2.4.4.7.              Safety connections for passenger cars (MA, MB and MC)
44.2.4.4.7.1.       Safety connections shall be capable of supporting a load equal to or greater than the trailer's 'Gross Trailer Mass'.
44.2.4.4.7.2.       Safety
