Leadfooted New Yorkers are now on notice.

The state just passed a massively expanded speed camera bill that calls for installation of as many as 2,250 of the devices in 750 school zones in the city.

The new law expands on the 140 speed cameras that are currently in place in the five boroughs.

The law — which was sponsored by Sen. Andrew Gounardes and Assemblymember Deborah Glick and passed on Tuesday afternoon — also expanded the hours that the speed cameras can be turned on. The previous law only allowed them to be in operation from one hour before school starts to one hour after school ends.

The new law will allow them to issue tickets to speed demons from 6 a.m. to 10 p.m. every weekday.

The law is far bigger than the 290 cameras that Gov. Andrew Cuomo had suggested in his budget plan. Cuomo said he will sign the bill.

“I support speed cameras,” he said at a press conference on Tuesday afternoon.

The cameras would be phased in over three years, said city Department of Transportation Commissioner Polly Trottenberg, who added that this would be the most expansive school camera zone program in the country.

“We want to get the program up and running as fast as possible,” she said. “We have some contractual issues we are working through for us we want to make this program the gold standard, we want to be data driven we want to be thoughtful, we want to have them go up quickly but do it in a thoughtful way.”

The DOT issued 616,952 speed camera tickets from September of 2018 to February of this year, agency officials said.
