Odometer accuracy is no longer defined. What this means: For a vehicle travelling at a true speed of 100km/h, the speedo must read between 100km/h and 114km/h.
How much accuracy do speedometers need to be accurate?
Until July 2006 this rule specified an accuracy of +/- 10 percent of the vehicle’s true speed when the vehicle was travelling above 40km/h. That is, at a true vehicle speed of 100km/h the speedo could indicate between 90km/h and 110km/h.
