Yellow = Go really fast
Red = Stop
I have since come to believe that the third definition is no longer applicable. With the new technology that most of our cities are employing, the Red signal should now read: "Smile, we just took a picture of your license plate."
No matter which way you decide to go, you're screwed. And don't expect me to take the blame for it, you were the idiot who chose this road in the first place. My advice to you is take your best shot pal, you might get lucky...
You and your car do not need to be here under any circumstances, so just leave. Of course, if you choose to disagree, please feel free to stop here and stay a while. There will be no consequences. (Do you think they bought it?)
Please be advised that the people around here are not the only things that experience Road Rage.
Of course these instructions make no sense, but what did you expect? Being confused about it won't do you any good. No matter which way that you decide, we are going to give you a ticket. Pretty funny, huh ?
This may be the only truly honest sign that I discovered. It is clear, to the point, and always correct.
