What should you do when you see a yield sign?

Answer: B — Slow down and yield to oncoming traffic.

When you see a yield sign, it is essential to understand that its primary purpose is to alert drivers to slow down and be prepared to yield to any oncoming or cross traffic. The yield sign indicates that you must give the right-of-way to other vehicles or pedestrians who are already on the road you are entering or crossing. In practical terms, this means approaching the intersection with caution, assessing the traffic conditions, and only proceeding when it is safe to do so—ensuring that you do not impede the flow of traffic. This approach prioritizes safety for everyone on the road and helps prevent accidents. The other options do not align with the correct action associated with a yield sign. Coming to a complete stop may be excessive unless it’s necessary for safety reasons, speeding up to merge conflicts with the innate caution required when approaching a yield, and ignoring the sign can lead to dangerous situations and potential collisions. Always remember that the yield sign is there to ensure a safe merging process or lane change.
