Final answer:
Drivers must yield to pedestrians in an unmarked crosswalk for pedestrian safety and accident prevention.
Step-by-step explanation:
The statement is true. Drivers must yield to pedestrians in an unmarked crosswalk. An unmarked crosswalk refers to any area where pedestrians are crossing, even if there are no painted lines on the road. In most jurisdictions, drivers have a legal obligation to yield to pedestrians in crosswalks, whether marked or unmarked. This is to ensure pedestrian safety and prevent accidents.
