A Manhattan judge has put the brakes on a class-action lawsuit challenging the city’s red-light-camera program.

“Plaintiffs cannot assert in good faith that it is against equity and good conscience to allow a municipality to levy fines against individuals who drive through red lights and thus pose a danger to society,” Manhattan Supreme Court Justice Kathryn Freed wrote in her decision released Monday.

The two Brooklyn drivers, David Halberstam and KellyAnn Williams, had sued the city in 2012 claiming their $50 fines were unfair.

They were arguing that the yellow-light signals in their cases were shorter than required by federal law, putting the whole program into question.

But Freed said they failed to show that the city knew the traffic lights “remained yellow for less than 3 seconds,” and upheld the program in general.
