Final answer:
The correct response is to yield to traffic already on the expressway when merging. Matching the speed of traffic is important, but must be done safely; using the shoulder or merging abruptly is not recommended or safe. B. Yield to vehicles already on the expressway.
Explanation:
The correct answer to the question regarding the truth about merging onto expressways is: B. Yield to vehicles already on the expressway. When merging onto an expressway, it is important to yield to the traffic that is already on the expressway, as they have the right of way. You should adjust your speed to find an appropriate gap in traffic, but this must be done without disrupting the flow of traffic already on the expressway. While you do want to match the speed of traffic to facilitate a smooth merge, it's essential not to do so abruptly or in a way that could cause danger or confusion to other drivers.
Using the shoulder to merge is typically not recommended or legal as it could be unsafe and is generally reserved for emergencies. Therefore, choices A, C, and D offer either incomplete or incorrect driving practices for merging onto an expressway.
