bare in mind people that what your speedo says and the speed you are actually doing a very different. speedos are in general not very accurate!
Legally there is an allowable tolerance of +/- 10% in the UK, more likely to be a +10% reading, even on your digital readouts.
The legal requirement is as follows:
The Road Vehicles (Construction and Use) Regulations 1986, as amended, allows the use of speedometers that meet the requirements of EC Community Directive 75/443(97/39) or ECE Regulation 39. Both the EC Directive and the ECE Regulation lay down accuracy requirements to be applied at the time of vehicle approval for speedometers. These requirements are that the indicated speed must not be more than 10 per cent of the true speed plus 4 km/h. In production, however, a slightly different tolerance of 5 per cent plus 10 km/h is applied. The requirements are also that the indicated speed must never be less than the true speed. In theory when you think you are doing 30 you could be only doing 24 mph though I don
