When you drive in a new state, it’s good to look up whether the state is “permissive yellow” (e.g. California and Washington) vs “restrictive yellow” (e.g. Oregon) as well as whether it allows “right turn on red”.

A "restrictive yellow" light would be paired nicely with a speed trap, to increase revenue, since people will be monetarily motivated to "floor it" to avoid fees.

Wait, "right turn on red" is a state-by-state law? It's been a while since I drove in the States, but I always thought this was the rule everywhere.

All traffic laws are state-by-state (or even more local) in the US, in general.

In practice, according to https://en.wikipedia.org/wiki/Turn_on_red#North_America everywhere in the US has had right turn on red unless otherwise signed since 1980. Except for New York City, apparently...

So, given the limited set of US States I've driven in, I don't appear to have been guilty of any violations.

Thanks.
