Red-light speed cameras
Red-light speed cameras are installed to reduce crashes at high-risk intersections with traffic lights. Crashes at intersections are often more severe with drivers and passengers vulnerable to side-impacts, while pedestrians have no protection in a crash.
Red-light speed cameras detect the speed of vehicles by using detectors embedded into the road surface or radar technology. Red-light speed cameras also detect vehicles travelling over the stop line or entering the intersection after the lights have turned red. If the speed of the vehicle exceeds the legal limit, or a vehicle runs a red light, a digital picture is taken of the offending vehicle.
Frequently asked questions
If an offence is detected, a digital image of the vehicle is recorded. The image clearly shows the colour, type, make and number plate of the vehicle. Digital images also include:
- Date of the offence
- Time of the offence
- Location details of the camera that took the picture
- Direction of travel of the offending vehicle
- Speed of the offending vehicle
- Speed limit on the road where the camera is positioned
- The lane that the vehicle was travelling within
- Other security and integrity parameters
Speed and red-light cameras can monitor multiple lanes with the use of detectors embedded into the road surface or tracking radar technology. Vehicles cannot avoid camera detection by straddling lanes.
Red-light speed cameras operate automatically day and night. Red-light cameras detect and record the speed of a vehicle by using vehicle tracking radar or electronic detectors that are embedded in the road’s surface. These detectors both accurately measure the speed of a vehicle as well as its location when the traffic lights change to red. If the speed of a vehicle exceeds the speed limit or enters into the intersection on a red-light, a digital photograph is taken of the vehicle.
A speeding vehicle can be detected and photographed even if it is within a line of vehicles. The angle at which the cameras are set enables pictures to be taken, even if another vehicle is close by.
The original recorded images are stored digitally and cannot be overwritten or altered. A security indicator prevents any attempt to tamper with the image at any stage. All images and relevant information (such as time, date and location) is encrypted. The original image forms the basis of the evidence produced in court. In line with legislative requirements, the photographs from speed and red light cameras can be tendered as evidence in court, together with appropriate evidentiary certificates signed by an authorised person.
Speed and red-light camera systems (including the digital camera recording device and the associated speed-measuring device) chosen for NSW undergo a comprehensive evaluation and testing procedure to ensure accuracy and reliability prior to their introduction. Transport experts inspect each camera system and verify its accuracy and proper operation before the commencement of the camera operation, and thereafter at regular intervals. The camera recording device is inspected every 30 days and the speed-measuring device is inspected at least every 12 months in line with current legal requirements. An inspection is also conducted following any maintenance or repair of either of these devices.
Camera sites are selected on crash statistics at intersections. The site selection criteria can be accessed on the Centre for Road Safety website.
- Signposting at intersections to alert drivers that the red-light speed cameras are installed and operational
- Roads and Maritime Service’s Camera Enquiry Line (1300 782 230) to answer specific enquiries from the public about red-light speed cameras
- Information about the program, including the location of the red-light speed cameras, is available to all road users and potential defendants on the Centre for Road Safety website.
If a vehicle is detected both speeding and running a red-light, two penalty notices will be issued and demerit points recorded for both offences. Double demerits apply for speeding offences during long weekends and holiday periods.
