Final answer:
Drivers must stop behind crosswalks for left or right turns and yield to pedestrians, especially at busy intersections by campuses to ensure safety. A traffic signal at these intersections can prevent dangerous situations, allowing pedestrians to cross safely.
Step-by-step explanation:
If necessary, stop behind a crosswalk when making left or right turns and yield to pedestrians in the crosswalk. Considering the context of pedestrian safety, it's important to emphasize that at intersections, particularly near campuses where students and others frequently cross, drivers should be vigilant. The introduction of a traffic signal at busy intersections significantly aids pedestrians, allowing them to cross at appropriate times without the need to dodge traffic, thus reducing the likelihood of accidents and ensuring the well-being of everyone involved.
Incidents that illustrate the necessity of this rule include a situation where a student must cross a busy intersection to reach campus. A traffic signal regulates the flow of vehicles, making it safer for pedestrians. And in a more dramatic context, a story where a pedestrian crossing slowly is protected by someone holding the traffic, highlights the human element in traffic safety and the importance of giving priority to pedestrians at crosswalks.
