Final answer:
You are not required to stop for an ice cream truck on a dual highway when you are on the other side of a safety island or median.Therefore, the correct answer to this question is d).
Step-by-step explanation:
You needn't stop your vehicle for an ice cream truck when: d) On a dual highway if you're on the other side of a safety island or median from the ice cream truck. In such a scenario, the physical barrier between directions of traffic implicitly allows you to continue without stopping,
as the safety concerns addressed by stopping for an ice cream truck (such as children crossing the road to reach the truck) are mitigated by the presence of the median or island.
This is similar to how a traffic signal manages the flow of vehicles and pedestrians, increasing safety and reducing accidents.To answer when you needn't stop your vehicle for an ice cream truck, let's consider each option provided:
a) It shows flashing red lights - Typically when an ice cream truck or any similar service vehicle shows flashing red lights, it is an indication that you must stop or yield as the vehicle may be serving customers, and pedestrians, often children, could be in the vicinity.
b) It shows a stop signal arm - Similar to a school bus, if an ice cream truck has a stop signal arm extended, you are required to stop. The stop signal arm is used to ensure the safety of pedestrians who may be crossing the road to or from the vehicle.
c) A person is crossing the roadway to or from the frozen dessert truck - When someone is crossing the road to or from an ice cream truck, it is imperative to stop in order to avoid endangering the pedestrian, again often a child. d) On a dual highway if you're on the other side of a safety island or median from the ice cream truck - On a divided highway with a safety island or a median separating the two directions of traffic,
you generally do not need to stop if you are on the other side of that physical barrier from the ice cream truck. The safety island or median provides a buffer between the traffic lanes, making it unlikely pedestrians would cross to your side of the road from the ice cream truck.
From these points, the only situation where you are not required to stop is option d) "On a dual highway if you're on the other side of a safety island or median from the ice cream truck." Therefore, the correct answer to this question is d).
