Final answer:
The correct option is A. Driver A should not assume the right of way. Extra caution is important at intersections for pedestrian safety and to ensure vehicles do not speed through traffic signals. Traffic signals help reduce accidents and improve safety for all users of the road.
Step-by-step explanation:
Driver A should not assume right of way when a private drive or side street is near a main intersection. Drivers must be cautious and consider various factors that affect safety, such as the possibility that other vehicles may not yield, pedestrian safety, and the potential for nearby traffic signals to change. For instance, when many vehicles speed through an intersection without regard for the speed limit, a traffic signal can make them slow down.
Additionally, pedestrian safety is a significant concern. Students and others crossing the intersection to access campus must sometimes dodge traffic, which is unsafe. Installing a traffic signal would greatly improve the situation by allowing for pedestrians to cross at designated times.
Finally, the presence of traffic signals can help reduce the number of accidents. When accidents occur frequently at an intersection, and the situation becomes critical, such as with fatalities, it's evident that adding a traffic control measure like a traffic signal can be justified and beneficial for community safety.
