1. Merging
Merging is the process of joining a stream of traffic from another lane or road, such as when an entry lane joins a motorway or when two traffic lanes become one. The merging driver must observe surrounding traffic, signal when required and enter an appropriate gap safely.
Drivers already in the continuing traffic lane should remain alert to merging vehicles and avoid unnecessarily preventing them from joining. Special zipper-merging rules may apply when traffic is heavily congested and a lane ends.
Does New South Wales distinguish between merging and changing lanes?
Yes. In NSW, if your marked lane ends and you must cross a broken lane line, you must give way to vehicles already in the lane you enter. Where lines of traffic merge without a dividing lane line, the vehicle behind gives way to the vehicle ahead.

Is the same merge rule necessarily used everywhere in Australia?
Australian road rules are applied by states and territories. The NSW distinction between a lane change across a broken line and an unmarked merge is a useful example; follow the markings and the rules applicable in the state or territory where you drive.
