In Idaho, where they also have 65+ mph highways with traffic light intersections, they have the "stop light ahead" signs, but instead of having long yellow lights, there are lights on the "stop light ahead" sign. (The lights on the sign will start flashing several seconds before the traffic lights change to yellow.) The rule is basically the same though, if you pass the sign before its lights start flashing, you'll make it thru the intersection, otherwise, start slowing down.

We have these in places in Florida. I still slow down (but not slower than the posted min) through these intersections. I've seen way too many accidents on these types of intersections to trust anybody.
