Final answer:
At an uncontrolled T-intersection, the vehicle on the terminating road is required to yield. This maintains the flow of traffic on the through road and ensures safety.
Step-by-step explanation:
At an uncontrolled T-intersection, the vehicle required to yield is the one on the terminating road, i.e., the road that ends at the intersection. The reason for this rule is to maintain the flow and safety of traffic on the through road, where vehicles are typically traveling at consistent speeds and may not expect the need to stop.
In contrast, a vehicle approaching from the terminating road must be extra cautious since it is arriving at the intersection where the normal flow of traffic does not include stops or interruptions. Therefore, the correct answer to the question is 2) Vehicle on the terminating road. It's important to follow these traffic rules to ensure safety and prevent collisions at intersections.
