Red light camera

A red light camera (short for red light running camera) is a type of traffic enforcement camera that captures an image of a vehicle which has entered an intersection in spite of the traffic signal indicating red (during the red phase). By automatically photographing vehicles that run red lights, the photo is evidence that assists authorities in their enforcement of traffic laws. Generally the camera is triggered when a vehicle enters the intersection (passes the stop-bar) after the traffic signal has turned red. Typically, a law enforcement official will review the photographic evidence and determine whether a violation occurred. A citation is then usually mailed to the owner of the vehicle found to be in violation of the law. These cameras are used world-wide, in countries including: Australia, New Zealand, Canada, the United Kingdom, Singapore and the United States. If a proper identification cannot be made in lieu of a ticket, some police departments send out a notice of violation to the owner of the vehicle, requesting identifying information so that a ticket may later be issued.
