The color green had caused more bad judgment and rash decisions among drivers not to yield and end up anticipating too quickly. So, the FHWA decided to mandate the use of FYA (Flashing Yellow Arrow) at intersections, high volume or not, to initiate better safety guidelines for drivers. The FHWA did a study and concluded that the flashing yellow arrow resulted in fewer accidents than stale green had. The implementation has been in effect for about ten years. Flashing yellow is in, and stale green, eventually, will be OUT!

Flashing yellow arrows are here to stay. It's a better system and people all over are still making adjustments to it at the intersections that currently employ it. This implementation is being done in phases throughout the country. Yes, it's now mandatory. People just have to yield to oncoming traffic until clear, then make the left turn. Stale yellow is still going to be a signal to slow down and prepare to stop for red.
Flashing yellow arrows are not mandatory. Some states are making it policy for permissive left turns, but there is no FHWA mandate to implement them.

How this is an improvement, is a mystery to us.
That isn't the fault of the flashing yellow arrow. Clearly those were not good places to allow permissive left turns, and a circular green would not have made the intersection any safer. If you can't see oncoming traffic, left turns should be protected or prohibited. Where you *can* see oncoming traffic, they are an improvement over a circular green for permissive left turns.
