Commonwealth Department of Transport and Regional Services, Review of Australian Design Rule (ADR) 18 – Instrumentation, Regulation Impact Statement for Standards for Instrumentation, Public Comment Draft Sept 2003 :

“The ADR requires visual indicators to meet specific location requirements and provides detailed visibility requirements for visual indicators for passenger cars and three wheeled passenger vehicles. It also provides technical requirements for speedometers and odometers and one particular aspect is that it allows a tolerance on the indicated speed of + 10%. This means that the vehicle could be traveling 10% faster than the indicated speed, thereby exposing motorists to inadvertently exceeding speed limits. This has become a particular problem as jurisdictions tighten up on their speed enforcement regimes, reducing their tolerances below the ADR allowed tolerance .”
