What is the purpose of a yield sign?

The purpose of a yield sign is to indicate that drivers must yield the right-of-way to other traffic. This means that when you encounter a yield sign, you are required to slow down and assess the traffic conditions. If there are vehicles or pedestrians in your path, you must give them priority before proceeding. The yield sign is designed to enhance safety by preventing accidents at intersections or when merging into traffic, ensuring that all road users can navigate safely.

In contrast, the other options do not reflect the true function of a yield sign. For instance, indicating that drivers should speed up is unsafe and contrary to the yield sign's purpose of increasing caution. Similarly, marking a stop required at intersections relates to a stop sign, which has a different directive. Lastly, signaling a school zone ahead is related to specific signage intended to warn drivers to be cautious around schools, not a yield sign. Understanding the yield sign's function is crucial for navigating intersections and sharing the road responsibly with other users.
