What does a green arrow indicate?

A green arrow is a traffic signal that means it is safe to proceed in the direction the arrow points. This indicates that drivers have the right of way and can move forward without needing to stop for oncoming traffic or other obstacles that would typically require yielding. The green arrow typically accompanies a red light for other lanes of traffic, which reinforces the safety of proceeding in that specific direction. Understanding this signal is crucial for safe driving, as it helps manage traffic flow and reduce the risk of accidents at intersections.
