There are two key rules you should be aware of when it comes to merging, and it all comes down to the line markings:

Dashed: The first kind of merge is when vehicles cross a dashed line – like on a freeway. Here the vehicle wanting to switch lanes needs to give way to cars already travelling in that lane.

The first kind of merge is when vehicles cross a dashed line – like on a freeway. Here the vehicle wanting to switch lanes needs to give way to cars already travelling in that lane. No dash: In a zip-merge situation – which is when two lanes of traffic join and there’s no dashed line – the vehicle in front should be given way regardless of whether they’re on the left or right.

When it comes to changing lanes – regardless of whether there’s line marking – you must indicate. The signal must be long enough to give enough warning to other drivers. So, no flicking on your indicator at the last minute!
