What should a driver do when entering an expressway in the acceleration lane?

When entering an expressway, a driver should use the acceleration lane to gain speed and merge safely into the flow of traffic. The correct choice emphasizes the importance of searching for a gap in traffic and adjusting speed accordingly. This approach allows the driver to match the speed of vehicles already on the expressway, facilitating a smooth and safe merge.

Additionally, finding a suitable gap in traffic before entering ensures that the driver can merge without causing disruptions or hazards to other vehicles. Simply speeding up to the highest velocity possible may not be safe or practical if there are no available gaps in traffic. Stopping completely before merging is not advisable, as it can create a dangerous situation, disrupting the flow of traffic. Signaling right and waiting for a larger gap can also lead to unnecessary delays and confusion for other drivers, making it essential to be proactive in assessing the traffic situation while adjusting speed to fit seamlessly into the existing stream of vehicles.
