Final answer:
Anytime you want to merge with other traffic, you need a gap.
Step-by-step explanation:
Anytime you want to merge with other traffic, you need a gap.
Merging is the act of joining and blending with the flow of traffic from one lane to another. To do this safely, you must find a suitable gap in the traffic stream that allows you to enter without disrupting the flow. This means you need to consider the speed and spacing of the vehicles around you.
For example, when merging onto a highway, you might wait for a gap in the traffic and then accelerate to match the speed of the vehicles already on the highway. This ensures a smooth and safe merge.
