Answer :
Final answer:
A red triangle 'Yield' sign means to slow down and yield to oncoming traffic when merging, not to stop completely or merge at regular speed without yielding. So the correct option is A. Slow down and yield to traffic on main road when merging.
Explanation:
The sign shaped like a red triangle with the word "Yield" means you should slow down and yield to traffic on the main road when merging. This sign is used to assign the right of way at intersections where it may not be practical to have a stop sign or traffic signal. It does not mean to always come to a complete stop; rather, you should slow down, check for oncoming traffic, and proceed when it is safe. It is also not correct to proceed into traffic at regular speed without yielding just because you are using your turn signal. Understanding traffic signals and signs is crucial to ensuring road safety and efficient traffic flow.
