What should a driver do upon seeing a yield sign?

A yield sign indicates that a driver must slow down and be prepared to stop if necessary to allow other vehicles or pedestrians the right of way. The correct response is to yield to traffic on the crossroad, as this ensures that the driver is aware of and responsive to any vehicles that may already be traveling on that road.

This practice is essential for maintaining safety on the road, as it allows for smooth traffic flow and reduces the likelihood of collisions. When approaching a yield sign, drivers should assess their surroundings, including both pedestrians and oncoming vehicles, and yield accordingly.

Option C illustrates this principle accurately, emphasizing the importance of giving way to other traffic. While yielding to pedestrians is also vital, the primary focus at a yield sign is to ensure to oncoming vehicles that may not be stopping or slowing down, which is why this option is the best choice. Other responses suggest actions that could lead to unsafe situations or misunderstandings regarding the yield requirement.
