(1) A drawbar-type
coupling, or drawbar eye, used in a road train must be built and positioned

the road train is moving, the drawbar can move at least 15° upwards or
downwards from the position it occupies when the road train is parked on level
ground; and
(b) the
pivot point of the coupling is not over 300 millimetres forward of the rear of
the trailer to which it is attached unless another rule of this jurisdiction
allows a greater distance; and
(c) it
is at a height of at least 800 millimetres, but not over 950 millimetres, when
the road train is unloaded and parked on level ground.
(2) The requirements
of subrule (1) (b) apply to a vehicle instead of the corresponding
requirements in the relevant ADR.
