Following on from your comments regarding the legal error rate allowable in speedos, where would one stand if, following a series of "surprising" speeding fines, it transpired that my vehicle's speedo was inaccurate in reading slow by 17 per cent. While I did not take any action at the time I did carry the letter from the firm that fixed the speedo for a number of years in case I found myself in the position of possibly losing my licence due to accumulation of points. If a speedo can be legally inaccurate to the extent you mention one trip up the highway to Gympie would very likely see sufficient points accumulated to cost a licence.

For starters, if the speedo was reading slow it would not be legal, it can only read faster than the real speed. The bottom line is that the law requires you to drive within the speed limit, so the responsibility is on you to obey the law. Unfortunately the responsibility isn't reduced by your speedo being inaccurate. Of course, you could contest the allocation of points in court.
