Final answer:
A green arrow on a traffic light indicates the driver has the right of way to make the turn in the direction of the arrow, which can either be a left or right turn depending on its orientation.
Step-by-step explanation:
A green arrow on a traffic light generally indicates permission to proceed with a turn in the direction of the arrow. This can mean:
- A right turn if the green arrow points to the right.
- A left turn if the green arrow points to the left.
U-turns or proceeding straight ahead are typically not indicated by a green arrow but are subject to the regular green light or specific signage.
In your specific question, without an accompanying image to indicate the direction of the green arrow, the answer could refer to either a right or left turn, depending on the arrow's direction. U-turns and proceeding straight ahead are not commonly associated with green arrows.
