What does a green arrow indicate at a traffic light?

A green arrow at a traffic light is an indication that drivers can proceed in the direction of the arrow. It signifies that the way is clear for that specific lane of travel. However, it is essential to yield to any pedestrians who may be crossing the intersection in accordance with traffic laws. This ensures safety for both drivers and pedestrians, making it clear that while you have the right of way to move forward in the direction indicated by the arrow, you must still be cautious and observant of other road users.

The other choices suggest scenarios that do not apply to the meaning of a green arrow. For instance, the notion of waiting or stopping contradicts the purpose of the green arrow, which is to grant permission to proceed. Moreover, a green arrow does not imply traffic closure; instead, it actively indicates that traffic is permitted to continue.
