A green arrow indicates that you:

A green arrow provides a clear directive for drivers, signifying that they can proceed to turn in the direction of the arrow without any restrictions. This signal indicates that it is safe to make a turn, as it often accompanies a traffic signal that may be red or yellow for other approaching vehicles. The green arrow effectively grants the driver right-of-way, meaning they do not need to stop or yield to oncoming traffic when moving in the indicated direction.

In contrast, a stop, slowing down, or yielding would be appropriate responses to different signals such as a red light or a yellow light. A red light requires a complete stop, while yellow signals caution to slow down, as the light is about to change to red. Yielding to oncoming traffic typically occurs at intersections or when turning left, but with a green arrow, the right-of-way is explicitly given to the driver turning in the direction of the arrow. Thus, the green arrow serves as a clear and affirmative signal for proceeding safely.
