Final answer:
The Green Arrow on a lane use control light indicates that you can make a turn in the direction of the arrow while other vehicles are stopped.
Step-by-step explanation:
The Green Arrow on a lane use control light indicates that you are allowed to make a turn in the direction of the arrow. It means that you have the right of way to proceed with your turn while other vehicles coming from the opposite direction are stopped.
For example, if you see a Green Arrow pointing left, you can safely turn left at the intersection even if the main traffic signal is showing a red light.
Remember to always check for oncoming traffic and pedestrians before making your turn.
