This is logical. But, I've seen firsthand in Quebec (the city of Sherbrooke) where that's not the case. A driver may have a green arrow at the SAME TIME that a pedestrian has a walk signal. And in St. Thomas USVI I've seen opposing traffic have conflicting signals too (green arrow at same time oncoming traffic has green to go straight!)
