Obviously it depends on the junction, but for anyone who’s not familiar with UK crossings here’s a touch more context:
It’s not necessarily all traffic at that entire junction, just traffic going across that specific crossing point that’s guaranteed to be stopped. So if there would be the possibility for a turn onto a road that has a green pedestrian light either all the traffic going that way would be on a red light, or there would be a filter light where only the relevant traffic (straight or a turn) would be on red.
