Answer :
Final answer:
The correct option when entering a freeway is to adjust your speed to the flow of traffic and merge safely. One should not stop or insist on right of way, but rather facilitate a smooth and safe transition onto the highway.
Explanation:
When entering a controlled-access highway or freeway, the most important action to take is to adjust your speed and merge safely with the flow of traffic. This means that option d) is the correct choice. Accelerating quickly to merge might not always be possible or safe, and coming to a complete stop before merging or insisting on the right of way can be dangerous and cause accidents. Instead, drivers should match the speed of traffic and use turn signals and mirrors to integrate into the flow of vehicles without causing disruptions. Traffic engineers and highway safety protocols emphasize the importance of smooth transitions onto a freeway to maintain the safety of merging operations.
