Road shoulders are marked by yellow edge line to the left of the road and white solid lines to the right edge of the road where multiple lanes going in the same direction.

You may not drive on the shoulder or to the left of the yellow edge line of the road, except to allow another vehicle to overtake and only if:

1. It is safe to do so; and
2. You have at least 150 metres of visibility; and
3. it is daytime (between sunrise and sunset); and
4. it is a single-lane roadway

Generally, you should keep within the lane lines. You should enter a lane or cross a road only if you are certain your vehicle is not likely to create a dangerous situation or obstruct traffic flow.

If you must change lanes:

1. Make sure it's safe before you start
2. Signal for at least three seconds before changing lanes
3. Before changing lanes, look over your shoulder to check that there are no vehicles in your blind spot.

Ideally you should get into the correct lane before you get to the intersection. However, if you must change lanes:

1. Make sure it's safe before you start
2. Signal for at least three seconds before changing lanes
3. Before changing lanes, look over your shoulder to check that there are no vehicles in your blind spot.

Never change lanes suddenly.

When there are overtaking lanes, drive in the left-hand lane unless you are overtaking another vehicle.

If you've been driving slower than the speed limit, don't speed up when you reach a overtaking lane if other vehicles are following – give them the opportunity to overtake you safely.

Special vehicle lanes have signs or markings that indicate they are only for the use of specific kinds of vehicles, such as buses, cycles, taxis or vehicles carrying a specified number of passengers (transit lanes). 

Some special vehicle lanes operate 24 hours a day for the use of the designated vehicles. Others have times of operation specified on their signs, for example, '4 pm to 6 pm'. In that case, you may be able to drive in them outside of these times.
