Got Caught By a Red Light Camera?

Ohio also just passed a new law requiring any citations issued from a red light or speed camera must be personally witnessed by a police officer. That effectively puts them out of business. Goes into effect April 1. However, Ohio cities that are using them are expected to take the new law to court, saying it is an infringement on Ohio's city home rule law. We'll see how this plays out. In Toledo, they budgeted $3.5 MILLION as income from their red light and speed cameras for 2015. Only about half of the notices ever get paid, and I don't know why anyone would pay them. The current law has no teeth, they can't issue a warrant or seize property (like a car), all they can do is send it to a collection agency, and they can't even put it on your credit record.

Red light cameras are ineffective. If intersections that have these cameras for some time still have a lot of violators, and camera citations are still issued in large numbers, what's gained other than the city and the camera owners making $$$ off them?
