A class action lawsuit against three red-light camera vendors and more than 70 Florida counties and cities is moving forward after a Miami federal judge rejected their motion to dismiss.

The ruling Monday by U.S. District Judge Federico Moreno tossed out some limited motions by the local governments—including procedural due process claims—but kept alive most of the plaintiffs' claims.

The suit involves hundreds of thousands of red-light tickets issued to Florida drivers since 2010. It was filed last October by two Florida residents on behalf of all motorists ticketed for running red lights based on camera photos.
