What is the purpose of yield signs?

Yield signs serve a crucial role in maintaining safe traffic flow at intersections and other merging points. Their primary purpose is to advise drivers to slow down and be prepared to give way to other vehicles or pedestrians that may have the right of way. This means that upon approaching a yield sign, a driver must assess the situation, reduce speed, and allow vehicles or pedestrians to pass if necessary, ensuring safety for everyone on the road.

Understanding the context of yield signs highlights their importance in preventing collisions and facilitating smoother traffic operations. The other options, while they may relate to certain traffic situations, do not accurately reflect the specific function of yield signs as they do not involve yielding the right of way.
