When are the WALK signal and green light typically active simultaneously?

The scenario where the WALK signal and green light are active at the same time typically occurs for drivers and pedestrians going the same direction. This situation is designed to enhance safety at intersections where both vehicles and pedestrians are present. When the WALK signal is illuminated, it indicates that pedestrians have the right of way to cross the street. If vehicles also have a green light, this usually means they are allowed to proceed straight or make a turn in the same direction pedestrians are crossing.

This arrangement necessitates caution from both parties: pedestrians should ensure that the vehicles see them and are stopping, while drivers must remain vigilant for pedestrians who might be crossing in front of them. The synchronization of the WALK signal and the green light helps facilitate a smoother traffic flow and improves safety when both drivers and walkers share the same path in a regulated manner.

In other scenarios, such as those considered in the other answer options, the dynamics and rules governing vehicle and pedestrian interactions are significantly different. For example, the presence of emergency vehicles typically does not apply to a WALK signal and green light simultaneously as they have their own protocols for navigating through traffic.
