Got caught by the camera doing a 38 in a 25. Speed zone cameras are in effect on weekdays from 6AM to 10PM (under Section 1180-b of the New York State Vehicle and Traffic Law). The time it captured my license plate was after 9PM. I am planning to dispute it online and they're asking me to explain why the violation should be dismissed. Any advice on mentioning the calibration of the camera or the fact that an officer was not present during the incident?
