Apparently there are but I’ve never encountered one. Plus traffic laws in the US are very vibe-based. It’s more of a set of cultural norms than actual rules. You do what everyone else does, regardless of the law, or you get hit by another vehicle.

inconsistent traffic laws make you safer by keeping you on your toes

in practice we just have “no right on red” signs or specific right turn signals at intersections where it would be problematic. out where everything is so spread out there isn’t any pedestrian traffic and bikes act like vehicles (and so are not alllowed to cut past cars on their right where they are liable to get hit).

as typical, american imagination about change is based on the assumption there will be no infrastructure to support it. no turn on red wouldn’t make sense as a blanket rule given current infrastructure due to a lack of bike or pedestrian infrastructure to take advantage of it and the obvious congestion problems that come from cars idling at a traffic light. actually create that infrastructure and the time lost to needing to sit at a red light so non car traffic can cross safely will be less than the time saved due to there being fewer cars on the road to begin with. imagine if the light wasn’t red to begin with because there weren’t other cars. imagine not having to drive at all.
