Speeding and running a red light are punishable offences under Queensland’s Transport Operations (Road Use Management – Road Rules) Regulation 2009.
Speeding makes it difficult for a driver to stop his vehicle while running a red light increases the possibility of crashing into a pedestrian or vehicle that has already crossed the road because of the red light.
Exceeding the speed limit and travelling at an intersection in violation of a red traffic light are kept in check by speed and red light cameras. There are locations where the camera is a combined speed and red light camera.
The locations of speed and red light cameras undergo careful research and study. One of the criteria for the location is the crash history in the area which means that it must have had at least five crashes in five years. Pedestrian population is also another factor. The crash potential of the site will also be considered since there are certain areas in Queensland that drivers tend to get careless and would just speed up like in tunnels.
Speed cameras may be categorized into mobile speed cameras and fixed speed cameras. A mobile speed camera is fitted into a vehicle and it monitors passing vehicles by emitting a radar beam at the road. The camera automatically takes a photograph of a vehicle that speeds through the radar beam.
Another type of mobile speed camera is the portable speed camera which basically functions the same way but the difference is that it is hand-held or may be set up on a tripod at the side of the road. The police handling these cameras may be in a marked or unmarked vehicle, wearing their police uniforms or plain civilian clothes.
Fixed speed cameras are permanent fixtures on roads or intersections. These cameras will detect a speeding vehicle, takes a picture of it and provides information like the location of the speeding, the time and speed.
Red light cameras are attached to a pole at intersections where there is a traffic light. The camera will take 2 photos. The first photograph that it takes is when you continue driving even though it is already a red light and the second photograph is taken 1 or 2 seconds after to show your location in the intersection.
The photos will be sent to the Traffic Camera Office along with the lane position, time and date that the driver ran a red light. Police officers will then issue an infringement notice to the driver for the violation.
