What does a green arrow signal indicate for drivers?

A green arrow signal serves as an indication to drivers that they can proceed in the direction indicated by the arrow, provided they are in the correct lane designated for that movement and the area is clear of obstacles or pedestrians. This signal often comes into play at intersections where there may be multiple lanes, advising drivers to move safely and confidently in the intended direction. It's crucial for drivers to be aware of their lane positioning, ensuring they are aligned with the permissible turn or movement as dictated by the signal.

In contrast, other options suggest scenarios that do not apply to the meaning of a green arrow. The idea of proceeding in any direction is incorrect, as the green arrow specifically directs movement in a singular, indicated direction. The option that instructs drivers to stop is also contrary to the purpose of a green arrow, which encourages movement. Finally, the notion that turning left is the sole action allowed does not encompass the entirety of what a green arrow might permit, particularly if the arrow points in another direction, such as right or straight ahead.
