What does a green arrow light indicate at an intersection?

A green arrow light at an intersection signifies that it is safe for drivers to proceed in the direction indicated by the arrow. This signal provides a clear direction to motorists, indicating that they have the right of way to turn or move forward safely, as there is no conflicting traffic.

For example, if the green arrow is pointing left, drivers may turn left without having to yield to oncoming traffic, as the signal indicates that they are allowed to do so. This helps improve traffic flow and enhances safety for vehicles making the allowed maneuver, as they are directing traffic efficiently and minimizing the chance of accidents.

Other options do not accurately describe the meaning of a green arrow. A stop and wait response applies to red lights or situations where traffic must yield before proceeding. Yielding to oncoming traffic is also not necessary when a green arrow is present, as it gives the driver the right of way. Therefore, acknowledging that a green arrow indicates a safe direction to proceed helps in understanding the rules of traffic management and safety at intersections.
