Speedometer accuracy
Under Tasmanian legislation, it is the motorist’s responsibility to ensure they do not exceed the speed-limit and that their vehicle’s speedometer is operating correctly.
Since June 2006, the Australian Design Rules require that new vehicles must have a speedometer that either shows the vehicle’s actual speed or faster (within 10 per cent plus 4 kilometre per hour).
The Speedometer Accuracy Fact Sheet provides a general guide for checking your speedometer is working correctly.
