I am pretty sure that several people have seen the new flashing yellow arrow traffic signals in a few places, where the flashing yellow arrow is used in lieu of a solid green ball light to indicate a permissive left turn.
I see that the point of these signals is to reduce yellow-trap (especially on a road that uses hybrid lead-lag phasing), however, wouldn't some people find such signals distracting due to the flashing? This was one of the very reasons why white strobes inside red signals have been banned.
As alternatives to a flashing yellow arrow, why not add a fourth color arrow? Perhaps a solid blue, purple, white, or pink arrow may have been a better idea than a flashing yellow arrow. Or what about a "reversed" yellow arrow signal, which would have a black arrow inside a yellow ball light?
A flashing yellow arrow does not mean the same thing as a steady green light, so it's not being "used in lieu of". There's the first mistake.
There's no need for a 4th color. People need to learn what the signals mean, and pay attention. If people are so easily distracted by a traffic signal, maybe they shouldn't be driving at all. Adding another color when the current system works fine is pointless.
Arrow means it applies to traffic moving in that direction.
Yellow means proceed but yield if necessary.
Flashing means it is not going to change to red in a moment.
I see you are from Arizona. I think Tucson and maybe Phoenix are "testing cities" for new or proposed traffic control signs and devices.
I have traveled around the country a bit and see all sorts of unusual traffic gizmos when I visit Tucson which I have not seen anywhere else. Many states have red arrows for left turns only - they remain red while the straight through traffic has a green light. The left turn light only turns green before the straight through traffic gets a green.
(In Tucson at least, when the straight through traffic gets a green, you get a flashing yellow for left turn and can turn left if no oncoming cars. Then it turns red briefly when the straight through traffic also gets a red, then green after that pause for left turn. Quite different from other states!)
Whoever came up with/installed these new flashing yellow turn signals is in fact LYING to motorists about whether they can safely turn or not, it's unethical, and they will definitely be going to hell for eternity.

They always have signs that say "Yield on yellow flashing arrow", so I don't see how it's unethical except to people who can't read (who probably shouldn't be driving anyway... LOL).
