What does a green arrow at a traffic signal mean?

A green arrow at a traffic signal indicates that drivers may proceed in the direction of the arrow, provided they yield to pedestrians who may be crossing in their path. This signal allows for a clear right of way, meaning that vehicles can move forward without the need to stop or wait for other signals, but they still have a responsibility to ensure that pedestrians have the opportunity to cross safely.

The significance of yielding to pedestrians is crucial because it highlights the importance of pedestrian safety at intersections. While vehicles can move when they see a green arrow, they must always be aware of any pedestrians who may be in or entering the crosswalk.

Understanding this helps drivers recognize the priority of pedestrian movement, even when traffic signals indicate that it's safe for vehicles to proceed. Thus, a green arrow conveys both permission to move and the necessary caution to ensure everyone's safety on the road.
