Final answer:
Upon seeing a yellow arrow in a dedicated right turn lane, you should stop and yield to oncoming traffic. If the way is clear, proceed with caution. Always follow traffic signals for road safety.
Step-by-step explanation:
When a yellow arrow appears as you wait in a dedicated right turn lane, the correct action to take is to stop and yield to oncoming traffic before making your turn. A yellow arrow signals that the protected turning time is about to end, and you must prepare to stop if it is safe to do so. If the way is clear of pedestrians and oncoming traffic, you may proceed with caution. It is important to always follow the traffic signals and rules to ensure safety on the road.
