I've never gotten a photo ticket, which I assume this is what this is. I would fight it as a matter of principle. You have to nothing to lose if you do. But sometimes, they dimiss the charges to avoid having deal with the issue all the way through the courts, since it may be constitutionally questionable.

At least I've heard of a few local cities in my state doing that on the red light camera tickets.

I personally think any kind of mechanically issued ticket is disgusting and violates so many legal and ethical principles, it's mind boggling. Why nobody stands up to this is beyond me.

In one of our towns, the local news media actually proved that the yellow light, ONLY, on the lights with red light cameras, was actually set to be shorter than all the other lights in the city. How do you like that?
