It varies state to state but in my experience it’s a single digit dollar amount fine and that’s it. Only in places that have adequate crosswalks everywhere and rarely enforced unless there’s been chronic pedestrian issues. In US, pedestrians always have right of way. Jaywalking laws are there as a deterrent to protect pedestrians as much as drivers. About the only place I’ve seen jaywalking laws enforced are university campuses. You’ve got throngs of young adults, on their own for the first time, and walking around everywhere in busy urban environments

Oh, we don’t walk. We drive everywhere, even if our destination is in the same neighborhood.
