Correct answer: Reduce speed and stop if the situation calls for it.
Answer options
AReduce speed and stop if the situation calls for it. Correct
BCome to a full stop every time, even when the way is clear.
CKeep the same speed and cross without needing to stop.
Why
At a YIELD sign you must reduce speed and let pedestrians and the traffic you are crossing or joining go first. If nobody is coming you can keep moving, but you have to stop whenever others have the right-of-way.
Tip A full stop at a YIELD sign is required only when traffic or pedestrians make it necessary.
