I got a red light ticket once. I had stopped in the intersection for a stray dog. Could not get it dismissed because the dog was in front of the car and the camera was behind me. They didn't have video back then. Supposedly now they have video.
My neighbor got one for his daughter's car when her boyfriend ran the red light. He went to the judge and told him who was driving the car and the judge said, and I quote, "You are responsible for the car because it is registered in your name". I wasn't aware of that rule.
