A circular traffic signal with a green light on indicates that we have priority of passage over other vehicles and therefore permits passage, except when the traffic situation is such that the vehicle could foreseeably come to a stop at an intersection, pedestrian crossing, or cyclist crossing, in a way that obstructs or blocks cross traffic.
When the green light is on for vehicles, pedestrians will generally face a red light, prohibiting them from crossing.
