Editing Speedometer (section)

===Australia===
There were no [[Australian Design Rules]] in place for speedometers in Australia before July 1988. They had to be introduced when speed cameras were first used. This means there are no legally accurate speedometers for these older vehicles. All vehicles manufactured on or after 1 July 2007, and all models of vehicle introduced on or after 1 July 2006, must conform to UNECE Regulation 39.<ref>{{cite web | title = Australian Design Rule 18/03 – Instrumentation |work=Road Vehicle Certification System |url= http://rvcs-prodweb.dot.gov.au/files/ADR%201803.pdf |access-date=7 January 2008 }}</ref>

The speedometers in vehicles manufactured before these dates but after 1 July 1995 (or 1 January 1995 for forward control passenger vehicles and off-road passenger vehicles) must conform to the previous Australian design rule. This specifies that they need only display the speed to an accuracy of ±10% at speeds above 40&nbsp;km/h, and there is no specified accuracy at all for speeds below 40&nbsp;km/h. 

All vehicles manufactured in Australia or imported for supply to the Australian market must comply with the Australian Design Rules.<ref>{{cite web |url= http://www.comlaw.gov.au/ComLaw/Legislation/LegislativeInstrument1.nsf/0/A678C717ABCB8D02CA2571CC0014D003?OpenDocument | title=Australian Design Rule 18/02 – Instrumentation | work = Commonwealth of Australia Law | access-date=14 January 2008}}</ref> The state and territory governments may set policies for the tolerance of speed over the posted speed limits that may be lower than the 10% in the earlier versions of the Australian Design Rules permitted, such as in Victoria.<ref>{{cite web|url = http://www.aussiemotorists.com/misc/msa-speedo.html | title = Vehicle Speed Measurement II |work=National Motorists Association Australia |year=2004 |first=Leslie |last=Felix |access-date=14 January 2008}}</ref> This has caused some controversy since it would be possible for a driver to be unaware that they are speeding should their vehicle be fitted with an under-reading speedometer.<ref>{{ cite web|url = http://www.parliament.vic.gov.au/rsc/DEMERIT/demerit3.htm#6 |work=Victoria Road Safety Committee, Inquiry into the Demerit Points Scheme |date=November 1994 |title=3.6 Accuracy of speedometers |access-date=14 January 2008}}</ref>
