What does a green arrow mean?

A green arrow indicates that drivers are allowed to proceed in the direction the arrow points. This traffic signal provides a clear indication that it is safe to go, whether it means making a turn or moving straight through an intersection, depending on the arrow's direction. The significance of the green arrow is that it grants right of way, often accompanied by other signals or signs, ensuring that drivers can proceed without hesitation as long as the way is clear.

In contrast, the other options suggest circumstances under which caution or a halt would be necessary, which is not applicable here. A green arrow does not require stopping, yielding, or specifying a turn direction solely to the right; instead, it conveys a positive instruction to go forward in the indicated direction confidently.
