The Roads Minister Duncan Gay is wrong when he says lane filtering is currently against the law.
If you pass a vehicle on the right in a line of traffic but don't cross the lane line on the right of that vehicle you are simply overtaking that vehicle.
In NSW it's not an offence to do it, but, if you pass a vehicle and travel between the left side of that vehicle and the lane line on the left of that vehicle then you are overtaking on the left, or overtaking nearside. That's an offence.
You can legally ride between a line of vehicles as long as the lane line, usually a broken white line, is on your right and the vehicle you are passing is on your left.
In NSW it's legal to ride 2 abreast and in fact if a bike was to overtake those 2 there is no requirement for the overtaking bike to leave the lane. That'd be 3 bikes in the one lane.
It's easy to see how uneducated comments create controversy.
