Fair or not? Could I have fought it?
I was on unfamiliar streets, a little after midnight after leaving a college DII club hockey game. I was traveling a street I had never been on and come to a T-intersection of the two lane street I was on intersecting a four-lane street. My street divided into a left turn lane and a right turn lane. It was after midnight and there were no cars behind me and not a car in sight on the four-lane street in a semi-industrial, semi-commercial area. I was in the right turn lane, and came to a complete stop because my light was red. I turned to the person with me and said, "Do you suppose I can turn right on red?" the reply was "Sure." The instant I moved there was a flash behind me, and I realized I had been photographed.
Several weeks later I received a $120 citation for turning right at a "no turn on red" intersection. Neither of us saw a sign, and I even looked for it while I approached the intersection. They presented a link to an online site that gave a series of pictures of my "crime", which included me stopped at the light, going through with the turn and one after my car was out of view. Not a car in sight but mine on either street in any of the pictures.
This happened 100+ miles from home, so I wasn't about to go back to fight it. I found out that the municipality had actually "sold" intersection enforcement to a private company that installed and maintained the cameras, so my fine wasn't even directly from the city.
I paid it just to be done with it. What should I have done?
