There is a wide discrepancy in speedos here in the UK., it is an accuracy of 10%, plus or minus.
To get to an accorancy of 1 mph would add £3,000 to the cost of a car.
Even our works cars, as Enforcement Officers, are allowed that discrepancy.
That is not the case your speedo accuracy is not + or - 10% the indicated speed must
always be lower than the true speed. I couldn't believe that we were ahead of the UK on this so I checked:
http://www.legislation.gov.uk/uksi/1...Dspeed%20lower
There's this bit in Section 19 of the UK design rules
1. The vehicle shall be fitted with a speedometer capable of indicating speed in mph at all speeds up the maximum design speed of the vehicle.
2. For all true speeds up to the maximum design speed of the vehicle,
the true speed shall not exceed the indicated speed.
3. For all true speeds of between 25 mph and 70 mph (or the maximum design speed if lower), the difference between the indicated speed and the true speed shall not exceed—
V / 10 + 6.25mph
where
V = the true speed of the vehicle in mph.
Despite the use of the archaic speed measurement this legislation says basically the same as ours except yours is even less stringent so when your indicated speed is 70mph your actual speed could be as low as approximately 58mph.
(70 - 6.25) - (70-6.25)/11
So as I say if you are exceeding the speed limit then your speedo
will be indicating well over the speed limit.
