Unless there is a specific law regarding bikes I don't know about, Arizona statute only forbids entering an intersection on red. As long as you have a tire over the line before the yellow turns red, you are legal.
What ARS is cited?
What is ARS? Didn't think they cite cyclist.
Just got a bicycle ticket for going to a yellow light. WTF? Are they bored here? Where can I read up regarding bicycle citations?
Arizona is THE state of tickets next to Florida. It's an infestation. I would hate to live in either places.

If there isn't an ARS cited, get it thrown out, its invalid.
