What must you always do when joining a dual carriageway?

When joining a dual carriageway, it is essential to give way to traffic already on the carriageway. This requirement is in place to ensure a smooth and safe merge into the flow of traffic. Vehicles traveling on a dual carriageway typically have the right of way, and those entering from an on-ramp are expected to look out for oncoming vehicles and adjust their speed accordingly to merge safely.

Failing to yield to traffic on the dual carriageway could lead to accidents, as vehicles may be traveling at higher speeds. Merging safely requires awareness of the existing traffic, which often involves checking mirrors and using the acceleration lane to match the speed of the vehicles that are already on the road.

The need to give way is a fundamental rule that helps maintain order and safety on multi-lane roads, facilitating a seamless transition between slower and faster-moving traffic.
