Drivers in Tennessee will not have to worry about getting a ticket for turning right on red at intersections equipped with red-light cameras. A judge recently denied a request by two Arizona-based camera companies who were trying to keep lawmakers from banning that particular type of ticket.

State lawmakers passed a law last year that prohibits cities from issuing photo-enforcement tickets for right turns at red lights when the only evidence is from a traffic camera.

The two camera companies, RedFlex and American Traffic Solutions, attempted to challenge the law in court, but a Knoxville judge ruled against the challenge.

Tennessee lawmakers considered numerous bills last year on enforcement cameras, including one to eliminate ticket cameras statewide. That bill did not pass. Other measures have called for further traffic studies and for countdown timers at intersections equipped with enforcement cameras.

OOIDA and other groups, including the National Motorists Association, are critical of red-light cameras, saying the primary focus is to generate revenue. The groups advocate for longer yellow-light times and other measures to make intersections safer.

According to American Traffic Solutions, 30-50 percent of revenue from red-light cameras comes from vehicles making rolling right turns.

Last year, the Los Angeles City Council terminated a $2.7 million contract with American Traffic Solutions, saying the program at 32 intersections continued to lose money despite fines of $466 per violation.
