I know this has been done in Sacramento for years. Yellow Lights at large higher speed (40mph) intersections (like Fair Oaks and Howe) have the yellow light set at the CalTrans minimum safe approach speed, which is often 25 mph. This is on a double lane left turn with traffic at or above the posted speed limit.

Good luck fighting that ticket, well within the California State law.

Too bad they don't have to set the yellow light timing consistantly. That probally wouldn't give you the 2x increase in citations.
