okay here it is
took some searching but i found it and i saved it its official
this is the final word on lane splitting
straight from the road traffic regulations act
each lane can be seen as a public road by a motorcycle ie. each lane is a full road and you may overtake a vehicle when you feel it is save to do
that way if you cross the line and move into the fast lane then passing a car should be done on the right so they can nail you for passing on the left in the fast lane
this subject is now closed
