What is the purpose of yield signs?

Yield signs serve a specific purpose in traffic management by instructing drivers to slow down and prepare to give way to other vehicles or pedestrians that have the right of way. When a driver approaches a yield sign, they must assess the situation and determine if it's necessary to stop based on oncoming traffic. This helps maintain a safe flow of traffic, allowing vehicles already on the intersecting road to continue moving while ensuring that all road users can navigate intersections or merging lanes safely.

The other options do not accurately reflect the role of yield signs; for instance, stop signs are designed to make all traffic come to a complete stop, while speed limit signs indicate the maximum speed a vehicle should travel. Additionally, signs regarding school zones are separate and developed specifically to enhance the safety of children by notifying drivers to be extra cautious in those areas.
