I have a Rand McNally Atlas from 1985 and it says in Connecticut it is illegal to turn right on red. Maybe that has changed. Anyone know? Anyway they should term it “Pause on Red” as very few people actually come to a complete stop. They treat it as a yield sign
Yes, traffic laws are passed at the state level, but the Federal government can strongly encourage a state to change its laws by withholding Federal highway construction funds (without which most of your state’s roads would go to hell) to state’s that don’t have laws they like.
This was how the speed limit was changed to 55 (later changed back of course) and the legal drinking age was raised to 21.
Is there anyone else here who is seriously concerned for the health and well being of a fellow poster who actually had to DRIVE in New York City??? 
FWIW, the way the law was explained to me when I took Driver’s Ed (admittedly this was a loooong time ago. Henry Ford was our instructor) was that it was legal to make a turn when the light was red as long as you turned into the adjacent lane. This covers the right-turn and the left-turn-onto-one-way scenarios but specifically excludes turning from and/or into the second available lane. If this is, in fact, correct it is a law honored more often in the breach than the observance.

I believe that NYC is the only place in the US where it is, as a rule, illegal to make a right on red.
