Aye that's right ^. ( bold).The Highway Code says
“watch out for pedestrians crossing a road into which you are turning. If they have strated to cross they have priority”
I know that’s a specific situation but I’ve always taken that to mean that the Highway Code gives a pedestrian right of way once they enter the carriageway
But do they have right of way if they step onto the A1? In front of you? I know you'd still try to miss them, but right of way for the pedestrian?
