Final answer:
The correct sign to indicate the end of a divided highway is the End of Divided Highway Sign. It is important for drivers to recognize this sign as it alerts them that the separation between opposing lanes of traffic will end, merging into a two-way road.
Step-by-step explanation:
The sign used to indicate the end of a divided highway is known as an End of Divided Highway Sign. This sign is important for drivers to recognize as it alerts them to the fact that the physically separated lanes for opposing traffic will soon come to an end, typically merging into a two-way road where vehicles will be directly opposite each other with no median or barrier.
Other signs mentioned, such as a Merge Sign, No Passing Zone Sign, and Stop Sign, serve different purposes. A Merge Sign alerts drivers that two lanes are going to combine into one, a No Passing Zone Sign indicates areas where drivers are not allowed to overtake and pass another vehicle, and a Stop Sign instructs drivers to come to a complete stop at an intersection.
Understanding road signs is crucial for safety and compliance with traffic regulations. In this case, option 1) End of Divided Highway Sign is the correct answer, signifying that the separated lanes will soon merge and no longer be divided.
