Traffic lights and arrows?

Question

What rules apply if the right turn arrow displays no arrow, although the lights are still operational?

Answer 1

If your state allows "right turn on red," that rule applies.

If not, you stay until you get a green light or arrow.

Answer 2

is it a solid green aftre the arrow has come and gone?  ... then you have to wait until the opposing traffic clears and then make your turn .
