Lane lines
A driver must not change lanes over a single continuous lane line (see example E).

Painted islands
A driver must not drive over a painted island that is surrounded by a single continuous line. However a driver can drive over the island if they are entering or leaving the road, or entering a turning lane that begins immediately after the painted island (see diagram below).

A driver must not drive over a painted island at a freeway on-ramp. It is also illegal to drive on a painted island that is surrounded by a double line.

What you have to do
Remember that you can only cross a single continuous centre line if you are entering or leaving the road or to avoid an obstruction. You can’t overtake or do a U-turn over a single continuous line or a double continuous line.
