Crossing the edge line of a road = $100 fine.
Crossing a continuous line when changing lanes = 2 demerit points and $100 fine.
Crossing a continuous centre line = 3 demerit points and $150 fine.
There are three types of single continuous (unbroken) lines:
1. Edge Lines
Are used to mark the edge of the road.
You can only cross over an edge line when entering or leaving the road or; passing a vehicle on the left that is turning right or making a U-turn.
2. Lane Lines
Are used to define multiple lanes travelling in the same direction.
If the lane line is continuous, don’t cross the line to change lanes.
3. Centre/Dividing Lines
Are used to separate lanes travelling in different directions.
If the centre/dividing lines are continuous, do not cross that line unless you are turning right (i.e. to leaving or entering the road) or making a U-turn. The same applies if there is a continuous line on the left of a broken or dotted centre line.
Exception - If you need to avoid an obstruction, you may cross the continuous centre line(s) or edge line providing you have a clear view of any approaching traffic.
