Western Australian Consolidated Regulations Western Australian Consolidated Regulations (1) Each agricultural
implement being towed on a road must be connected to the towing vehicle or, in
the case of an agricultural combination consisting of more than one towed
implement, to the implement in front of it, not only by a coupling but also
by —
(a)
safety chains that conform with and are fitted in accordance with
subregulations (3) and (4); or
(b) a
safe locking device that conforms with subregulation (2).
(2) The safe locking
device referred to in subregulation (1) must consist of a spring clip,
split pin or similar device which is designed to mechanically capture the
coupling to prevent the accidental disconnection of the coupling.
(3) Safety chains
referred to in subregulation (1) must —
(a)
consist of 2 chains;
(b) be
capable of keeping the agricultural implement in tow in the event of the

and to a substantial portion of the towing vehicle or the implement in front
of that implement, as the case requires;

as short as practicable;
(b) be
fitted in a crossed over position so as to prevent the forward end of the
drawbar of the towed implement from striking the ground in the event of
accidental disconnection of the coupling referred to in
subregulation (3)(b);
(c) have
their forward ends fitted to the towing vehicle or another towed implement, as
the case requires, as close to the pivot of the coupling referred to in
subregulation (3)(b) as practicable;
(d) each
have links with the constituent metal thereof having a minimum diameter of
10 mm; and
(e) each
be attached to each end by a ring or shackle which is made of steel with a
