U-turns and overtaking
Centre dividing line
A driver must not overtake (see example A ), or do a U-turn across a single continuous centre line (see example B), or a single continuous line to the left of a broken line.
However a driver can cross over a centre dividing line (except a double continuous centre dividing line) when entering or leaving the road (see example C).
The driver can also cross over a broken line to overtake or do a U-turn (see example D).
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.
