Regarding the red stoplight:
In Germany we have a rule that you may turn right if theres a sign permitting you to do so. In that case the traffic light is to be treated like a STOP-sign.
Functionally the same but inverted in the states, there are signs that tell you when it’s NOT allowed. Just a matter of which is more efficient, signing when it’s allowed or signing when it’s not.
