At an intersection, what does a green arrow mean?

The green arrow indicates that drivers may turn in the direction of the arrow while also having the right-of-way over any other vehicles or pedestrians. This means that if you see a green arrow pointing to the right, for example, you are permitted to make a right turn, and you can proceed through the intersection safely without having to yield to oncoming traffic. The presence of the green arrow specifically directs you to turn while it is clear, ensuring a smooth and safe maneuver.

In contrast, simply proceeding through the intersection may not encompass the full intent of the green arrow, as it specifically allows for turns rather than general movement in all directions. Stopping before entering the intersection or coming to a full stop is not applicable in this context since the green arrow permits movement without needing to pause for other traffic, assuming it is safe to do so.
