Red Light Camera

A red light camera is a traffic enforcement camera that captures an image of a vehicle which has entered an intersection against a red traffic light. By automatically photographing vehicles that run red lights, the camera produces evidence that assists authorities in their enforcement of traffic laws. Generally the camera is triggered when a vehicle enters the intersection after the traffic light 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 worldwide, in countries including: Australia, 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.

There is debate and ongoing research about the use of red light cameras. Authorities cite public safety as the primary reason that the cameras are installed, while opponents contend their use is more for financial gain than for safety.
