Final answer:
A broken yellow line in the middle of the road means passing is permitted in either direction, though safety, especially in pedestrian-heavy areas, remains crucial and can be further improved with traffic signals. The correct answer is B.
Step-by-step explanation:
A broken yellow line in the middle of the road typically indicates that passing is permitted in either direction, under safe conditions. This means that a driver can cross the yellow line to overtake another vehicle, provided there is no oncoming traffic and it is safe to do so. However, there are situations where extra caution is required, such as near intersections, where pedestrian safety is a concern and where traffic signals control the flow of vehicular and pedestrian traffic.
While a broken yellow line allows for passing, it's important for drivers to adhere to other traffic rules, including the posted speed limit. In areas near campuses or where there is a significant pedestrian presence, adherence to speed limits and awareness of pedestrian crossings is crucial for safety. Moreover, the installation of a traffic signal in such areas can greatly improve both the flow of traffic and the safety of pedestrians by providing designated times for crossing and managing vehicle speeds.
Therefore, a broken yellow line is not directly related to the issues concerning intersections with heavy traffic and pedestrian volumes referenced in the background information. Rather, the concerns mentioned highlight the importance of traffic control measures, such as traffic signals, to improve overall safety and order at busy intersections.
