    Most responding forces using 10% + 2MPH as per the now defunct ACPO (Association of Chief Police Officers) guidelines (not legislation), despite there being a tolerance guideline, that does not override the final decision of a police officer.

    ACPO replaced by National Police Chiefs' Council (NPCC).

    Hmmm - that seems very generous. Here in France, 5% is deducted from measured speed for a stationary installation and 10% for the new mobile-units fitted to vehicles which measure as they drive.

    Your ticket gives you both the measured speed, and the speed you are being fined for .

    At 40 kph over the limit the gendarmes/police take your licence away ( = temporary driving ban until you go to court ) and there will probably be a month ban, and at 50 kph they impound your car - unsure for how long, and can confiscate it if the offence is serious enough. Minimum fine outside town is € 68 and in a 50 kph limit € 135 with one point off your licence ( the system here is you start with 12 points and lose them for offences )

    If you look at national politics, reducing road deaths is the only policy that has been a success since, say 2007, and therefore (all ) governments have kept the pressure on and policing is much tougher than it used to be. Macron's universal application of the 80 kph limit on single-carriageway roads hasn't yet proved to be the outright success that he had hoped, and it did have the unexpected effect of launching the "gilets jaunes " protest movement.

    Not so much generous as fair, vehicle speedometers can be as much as 8% out so only a 5% margin would mean innocence motorist are penalised.

    If this opens ok for you, you will see that your answer is not correct ( if you believe this site )

    Kudos to you for wading through that verbiage. I couldn't find it, but believe you. Presumably though, that is -0/+10% plus 4kmh ?

    I think we all know how accurate , or not, the manufacturers are with their info.
    According to then speedo on my old 1.6 cortina it could do 125 mph.!!!!!!

    In France they have sensible speed limits. Most A roads have a 90/110/130km limit, unlike the UK where they are increasingly set to 40-50mph.
    In the UK Guidelines for considering prosecution are 10%+2mph but you will be directed to speed awareness at up to 10%+9mph. There is a financial incentive for the police as they can recover a portion of the "training" costs, whereas if you get points and a fine the money goes to the treasury .

    Not any more . Since last autumn the limit on single-carriageway roads has been reduced to 80 and it is only 90 on dual-carriageway where there is a fixed, permanent central separation ( I'm unsure if this has to be a fence/wall or if an earthen strip counts ) Some dual-carriageways do have different limits up to 110 kph, individually signed.
