..answering the cam photo ticket can sometimes be taken care of by knowing what day the cops are sched’ for appearance then requesting a different day to appear. Sometimes they just drop the issue

If you get one of these tickets, one of the first things you should determine is whether the photo enforcement system is operated by the police or a private company.

If it's the police, you might be better off paying the ticket because it will cost you less than your time and efforts in the long run. If it's a private company, then fighting it through a legitimate legal process means it will cost THEM more time and money in the long run. The private company is in business to make money, so the last thing they want to do is pay one of their employees to show up in court. I suspect that's the real reason why many of these charges are dropped once the motorist who receives the summons indicates that they're going to fight it.
