Final answer:
Drivers are legally required to yield to pedestrians in an unmarked crosswalk to ensure their safety. Traffic signals can further enhance pedestrian safety by controlling vehicle speed and providing safe crossing times.
Step-by-step explanation:
The statement that drivers must yield to pedestrians in an unmarked crosswalk is true. Pedestrian safety at intersections is a significant concern, especially in busy areas like school campuses. Without proper traffic controls like traffic signals, pedestrians can find themselves having to navigate through moving vehicles, which can be dangerous. These traffic signals play a pivotal role in regulating vehicle speed and providing safe crossing opportunities for pedestrians at appropriate times.
In the absence of traffic signals, drivers are legally required to yield to pedestrians crossing the road within any crosswalk, marked or unmarked, to ensure their safety. Therefore, the installation of traffic signals would not only make drivers slow down due to the control of traffic flow but would also formalize the crossing points for pedestrians, enhancing safety for all.
