Answer :
Final answer:
The correct answer is all of the above options. When merging onto the expressway from the left, it's essential to yield to traffic already on the expressway, safely match the speed of traffic, use signals, and merge when a gap is available, prioritizing safety and the particular challenges of merging from this position.
Explanation:
When merging onto the expressway from the left, the essential steps to take can differ slightly from merging from the right due to the typical higher speeds and sometimes shorter acceleration lanes. However, the fundamental actions remain focused on safety and efficiency when integrating into the flow of traffic. Among the options provided, the correct answer is (d) Yield to traffic already on the expressway. This entails matching the speed of the vehicles on the expressway as quickly and safely as possible, using your mirrors and turning your head to assess the traffic, signaling your intention to merge, and then merging into a gap in the traffic. Accelerating to match the speed of traffic is a part of this process, and while immediately merging into the right lane or signaling right might be part of an overall safe merging strategy, yielding and safely merging based on traffic flow is the primary action that might be differently emphasized when merging from the left due to the potential for higher speeds in those lanes.
