Final answer:
If you encounter a yellow arrow signal while turning left at an intersection, you must yield to oncoming traffic and pedestrians, and wait for the signal to turn green before proceeding with your left turn.
Step-by-step explanation:
If you encounter a yellow arrow signal while turning left at an intersection, you must yield to oncoming traffic and pedestrians, and wait for the signal to turn green before proceeding with your left turn.
The yellow arrow signal indicates that the left turn will soon be prohibited, and you should not initiate the turn once the arrow changes from green to yellow. It is important to obey traffic signals to ensure everyone's safety on the road.
