What does a green arrow indicate?

Answer: A — May turn in direction of arrow

A green arrow typically indicates that you are allowed to turn in the direction of the arrow shown. It is a signal that gives drivers the specific permission to complete the indicated turn, usually even when other movements are restricted, such as when there is a red light for the general flow of traffic. This helps drivers make safer and more efficient turns at intersections. In this case, the correct answer is A because a green arrow specifically allows the driver to make a turn in the direction indicated by the arrow.
