What does a green arrow next to a traffic light signify?

A green arrow next to a traffic light signifies that you can proceed in the direction indicated by the arrow. This means that drivers have the right of way to move in that specific direction, and they do not need to stop for oncoming traffic or pedestrians that may be crossing in that direction. It clearly indicates a safe movement, allowing the driver to continue without hesitation.

In contrast, other traffic signals are designed to ensure safety and caution. For example, a traffic light alone might indicate that you need to stop or yield, which is not the case with a green arrow. Therefore, understanding the significance of the green arrow helps drivers navigate intersections safely and efficiently, ensuring they follow the specific rules of the road as indicated by traffic signals.
