What does a green arrow indicate at a traffic signal?

A green arrow at a traffic signal specifically indicates that you may proceed in the direction of the arrow. This means that the intersection is clear for you to continue driving in that direction without needing to stop. The presence of the green arrow generally signifies that traffic in that direction has the right of way, and you can proceed safely, assuming all conditions are clear.

In situations where there are other signals or signs present, such as a red light or stop sign, those must still be obeyed. However, when only a green arrow is displayed, it overrides other signals pertaining to movement in the specified direction, ensuring that drivers have a clear indication that it is safe to move forward.
