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.

Who yields when leaving Indonesian roadside property?
