In the UK a blinking yellow means you can go if there’s no pedestrians but you’ll only ever get that at a pedestrian crossing on a straight road. Never an intersection. As in, a place where the only reason the light would ever change is a pedestrian pressed the button to request it. Usually then they’ll go red for a few seconds, then blinking yellow to allow extra time for slower people to cross.
At intersections you might get green arrows to indicate you can go only in that direction. For example it might allow going straight but not turning because pedestrians are crossing the side road.
There’s never a case where red means anything other than you must stop and I’ve never seen a case where both vehicles and pedestrians would get a green light for the same piece of road at the same time.
Interesting, so blinking yellow obviously means the same everywhere but where these are placed varies a lot. In Greece I’ve never seen green for both cars and pedestrians either, but there are many cases where pedestrians get green and cars yellow for the same part of road (usually when cars turn right at intersections). From the answers I take it the original comment probably meant cars turning into the path of other cars, not people, which sounds a bit better.
