What does a green arrow at a traffic signal mean?

Answer: B — Proceed in the direction of the arrow

A green arrow at a traffic signal indicates that drivers can proceed in the direction of the arrow without any concerns. It is a clear authorization to move forward, ensuring that the lane is open for travel. This signal combines the meaning of the green light, allowing safe passage through an intersection while also showing the specific direction in which vehicles are permitted to go. With a green arrow, drivers typically have the right of way and do not need to stop unless there are other unusual conditions, such as pedestrians crossing or emergency vehicles present. Understanding this signal is crucial for safe and efficient navigation at intersections, promoting smooth traffic flow.
