Final answer:
To safely leave the expressway after missing an exit, you must proceed to the next one. This adheres to traffic laws and maintains safety, as in the metaphorical example where an obstacle would be safely passed by traffic in the correct lanes. The working backwards heuristic is an effective problem-solving approach.
Step-by-step explanation:
Yes, if you miss an expressway exit, you are required to proceed to the next exit to leave the expressway safely. This is essential for maintaining the flow of traffic and avoiding potentially dangerous maneuvers such as backing up or attempting to cut across multiple lanes of traffic to reach a missed exit.
In the hypothetical scenario provided, if a car traveling in the furthermost lane from an obstacle like a rabbit allows the rabbit to cross all three lanes safely, it highlights the importance of staying in the correct lane for your intended exit well in advance.
Additionally, approaching complex problems by working backwards from a desired result is an effective strategy, as illustrated by planning a trip with potential traffic considerations to ensure timely arrival at a destination. Road signs are designed to be somewhat universal, but understanding and interpreting them correctly is crucial for safety.
