The cameras led to more than 700,000 tickets to drivers going 11 miles per hour or more over the speed limit from September 2008 to September 2009, the most recent data available, according to the Department of Public Safety. The mandated fines and surcharges on all those tickets would total more than $127 million, but they had generated just $36.8 million through September, Lieutenant King said.

Some of the people who got those tickets are contesting them in court and could end up having to pay the fine, but many of them have gone unpaid because drivers know they have a good shot at getting away with ignoring them. When people get tickets, they can pay without question, request a court date and fight the ticket, or simply ignore the ticket because law enforcement cannot prove they received it. The ticket becomes invalid if a violator who ignores it is not served in person within three months. It is nearly impossible to say how many people have ignored their tickets because courts do not track the figure.

Whatever the figure, overtaxed process servers cannot get to most of those people, and many of the citations go unpaid. That is part of the reason the speed cameras have not made as much money as expected. While certain to increase, that $36.8 million in revenue through September will still fall far below the $120 million a year that former Gov. Janet Napolitano hoped to put in the state’s coffers when she ordered up the program in early 2007.

The camera operator, Redflex, may not even be breaking even. It cost the company $16 million to install the cameras, and it got back $4.6 million from September 2008 to June, Lieutenant King said.
