Australia is considering using noise cameras [yahoo.com] to detect and fine drivers whos vehicle exceeds noise limits. Drivers could face fines of up to $1,200 where noice exceeds the prescribed noise limit by 15 decibels. NSW authorities last year trialled hi-tech noise cameras in the Wollongong and Bayside council areas. NSW Police are still reviewing the data obtained from the trial and have yet to announce a broader rollout of noise cameras. Police could also issue a $434 fine and three demerit points to motorists who start or drive a vehicle in a way that makes unnecessary noise or smoke, including unnecessarily revving an engine.
