On August 1, 2013 Governor Andrew M. Cuomo signed legislation that permits New York City to establish a five-year demonstration program to monitor school speed zones in New York City with speed cameras and to allow evidence captured on camera to be used to impose liability for speeding. This new law will enhance the safety of children, pedestrians and drivers in New York City school speed zones by encouraging drivers to drive with caution through these areas and supplement law enforcement efforts to catch violations and prevent accidents caused by speeding. 
New York City is authorized to set up cameras in 20 school zones. There was some discrepancy in media reports if this means they are limited to just 20 cameras or if they can put multiple cameras in each of 20 school zones, however more recent first-hand reports indicate that there are up to 120 cameras currently in operation. These camera can be moved from school zone to school zone as the city sees fit. The cameras can only operate during school hours and/or after-school activities. This is a 5 year pilot program - the law is set to expire on August 1, 2018 unless it is extended by the New York State Legislature.
