Western Australian Consolidated Regulations (1) A person shall
not, with intent to hinder or obstruct the passage of any vehicle or vehicles
on a carriageway, park or stop a vehicle on the carriageway in such a manner
as to cause the passage of any other vehicle on the carriageway to be
obstructed or hindered.
(2) A driver shall not
unreasonably obstruct the path of another driver or a pedestrian.
(3) In
subregulation (2), a driver does not unreasonably obstruct the path of
another driver or a pedestrian only because —
(a) the
driver is stopped in traffic; or
(b) the
driver is driving more slowly than other vehicles (unless the driver is
driving abnormally slowly in the circumstances).
Example of a driver driving abnormally slowly
A driver driving at a speed of 20 km/h on a
length of carriageway to which a speed-limit of 80 km/h applies when
there is no reason for the driver to drive at that speed on the length of
carriageway.
