Victorian auditor-general Des Pearson has today backed the reliability of the state's speed cameras after a lengthy audit process.
Pearson said in a report released today that while no technological system can be relied upon for 100 per cent accuracy, regular testing and maintenance procedures are in place to ensure the cameras are functioning correctly.
"While there can be no absolute guarantee over the accuracy of any system, the processes and controls in place provide a particularly high level of confidence in the reliability and integrity of the road safety camera system," Pearson said in his report.
The auditor examined the testing and maintenance practices behind the Victoria's speed cameras and determined that the program was sound and ensured accuracy of results.
"Maintenance and testing of fixed cameras is comprehensive and methodologically sound. Testing is conducted by appropriately accredited independent organisations. Testing and maintenance of fixed camera equipment, including annual certification testing, is frequent enough to maintain accuracy and reliability," Pearson said.
He added that camera testing practices developed by Victorian Department of Justice are strictly maintained to avoid the 2003 incident on Victoria's Western Ring Road where malfunctioning speed cameras led to all fines and demerit points being refunded to drivers.
The audit was sparked in January with the incoming Victorian Deputy Premier and Minister for Police and Emergency Services, Peter Ryan, saying that the public had lost faith in the speed camera system.
"Victorians need to have confidence that the state's traffic camera network is accurate and has proper oversight," the deputy premier said in January.
At the time, Ryan also announced plans for a weekly, online list of mobile speed camera locations.
