Are you saying that a right-turn can be green simultaneous with the pedestrian's crossing light being green?

Because where I'm from, traffic lights are not allowed to be set up like that. No simultaneous green for crossing traffic flows, unless otherwise indicated (eg, an extra warning light+sign under the turn's traffic light flashing when it's green and off otherwise).

A car turning on a green light can be simultaneous with the pedestrian's crossing light being green. The driver is obligated to see the pedestrian and wait.

What's not simultaneous is a green turn arrow with a green ped crossing. Intersections in the US are designed so that a green arrow will mean the driver has no conflicts and can proceed.

Not everyone (both drivers and peds) understands that distinction.

  • I feel like I see a lot of fairly crazy intersections in my US city, where it feels like they break at least one expectation of the simple red/yellow/green patterns from drivers ed. I wouldn’t want to trust anyone’s life to assuming that a green arrow should mean I have the unconflicted right of way, let alone that others are even paying attention to their own signal

solid green (right turn allowed) + pedestrian green (for crossing).

car and ped both have access to ped crossing. (Car should yield to any ped in crossing.)

Also, I drew a picture before I realized that this wasn't what you were asking about. But I like the picture.

  • There is a way to mitigate the danger somewhat by giving pedestrians green light first, so when the car turns they are already in the middle of the road.

Yes. This pattern is normal in the US.

While vehicles are traveling north and south, the walk sign for crossing north and south is available. But vehicles are typically allowed to turn in the same cycle, protected lefts with their own cycle are common. Some intersections have a dedicated arrow for right turns and those will signal no rights while a walk sign is on, but otherwise pedestrians and right turns conflict.

> Are you saying that a right-turn can be green simultaneous with the pedestrian's crossing light being green?

I can't think of many places that I drive where this isn't the case.

The pedestrian crossing lights are in sync with the traffic lights, if traffic going N/S is green then the pedestrian lights going N/S will also be green even if cars are turning E/W

  • I know at least one intersection that crosses a bike path and walking path near me that changed recents so now oncoming traffic goes with the walk signal while turns are forbidden, then only right turns are allowed, then only left turns. It takes slightly longer to go through the cycle (particularly on busy days where pedestrians don’t yield the street for people to turn), but otherwise makes it much less stressful to go through that intersection regardless of my mode of transit around it
