Final answer:
When encountering a yellow crosswalk sign, you must be prepared to stop if there are children in the crosswalk. This sign indicates the presence of a pedestrian zone ahead. Safety measures such as traffic signals and crosswalks ensure pedestrian safety and orderly vehicle traffic.
Step-by-step explanation:
When you see a yellow crosswalk sign, you should be prepared to stop if children are in the crosswalk. This sign is designed to alert drivers to the potential presence of pedestrians, particularly children, and indicates that there is a school or pedestrian crossing ahead. While you do not always have to stop when you see this sign, you must stop if there are people in the crosswalk or if there is a crossing guard signaling you to stop. The safety of pedestrians, especially in areas frequented by children, is of utmost importance. Not only do traffic signals and crosswalks help manage the flow of vehicles, but they also provide safe points for pedestrians to cross, reducing the need to dodge traffic and decreasing the likelihood of accidents.
