At least in Georgia, there's at least one yellow light with a speed limit sign attached. During active school hours, the yellow light will flash on and off. On my daily commute, there's two overhead flashing yellow lights. Previously, my Model Y would begin to brake and then speed back up, thinking it's a normal traffic light (prior to FSD). With FSD, it's at least smart enough to know not to brake; but it certainly doesn't read the speed limit from the sign, as it normally would.
