http://www.essex.police.uk/pages/pa/bt220200.htm "10% is the technically accepted margin of error for speedometers." http://ww2.northumbria.police.uk/ePolicing/Web/WMS.nsf/FAQContentDocs/FAQ004 821?OpenDocument "The standard ACPO (Association of Chief Police Officers) guidelines are 10%plus 2mph over the speed limit (i.e. 35mph in a 30mph zone) ... individual police officers can enforce below these guidelines if conditions justify this course of action."
