According to the Sydney Morning Herald 25 March 2011 (link here
) there has been a tolerance of only 3km/h for speed cameras up until now.
However, this tolerance is being axed.
The NSW tolerance has always been fiercely guarded but in 2007 the Victorian government revealed that its tolerance level was 2km/h for fixed speed cameras and 3km/h for mobile speed cameras, plus a discretionary tolerance.
Australian design rules used to allow for a 10% tolerance either way on car speedometers, but now the rules only allow for the tolerance above the actual travel speed. Where does this leave cars made before this change, which could potentially read 10% too slow? Will this be a possible argument for contesting fines?
