What action is required when approaching a yield sign?

Answer: C — Slow down and prepare to stop if necessary

When approaching a yield sign, the appropriate action is to slow down and prepare to stop if necessary. Yield signs indicate that drivers must give way to other vehicles or pedestrians that have the right of way in an intersection or when merging. This means that as you approach the yield sign, you should assess the traffic conditions around you. If there are no vehicles or pedestrians in the path, you may proceed without stopping. However, if there are vehicles or pedestrians present that have priority, you must either stop or yield to them, ensuring safe passage for everyone involved. This helps in preventing accidents and maintaining orderly traffic flow at intersections or merging lanes.
