Years ago the tolerance was 10kmh, it was changed to 10%, the ADR's require speedo accuracy to be within 10% if reading sloer than actual speed, no limit if reading higher than actual speed, most read 7-10kmh higher than the actual speed so if you were to sit your speedo on the limit you should never get done.
Victoria's tolerance is 1% for heavy Vehicles, 3% for all others, I'm suprised no one has challenged it in court yet.
