The law alllows -6 km per hour,or + 6 km per hour for the calibration of an anologue tacho,the question is can a copper nick you for speeding by asking for your tacho,as the true speed will be not be correct.
I have heard that if the police radar as not been checked before the police start their shift,you can argue,the speed is not correct,as the speed measuring device has to be checked daily.
No, plus it doesnt prove where you were when you were speeding, you could have been on private property which has no speed limit 
Certainly you can. Try driving through France with ADR or Germany at 60mph 
But in the UK, no you can’t, for the same reason you cannot use a tachograph to disprove a speed camera fine
Portuguese nicked me for one km per hour over the 80 km per hour limit on the IP5,i refused to pay,i was then put in an un-marked car to find a bank with an ATM,this was about 30 km`s away.
With ADR on the road from Bordeaux to Irun,it would wise to stick to the limit,even if you have 100 trucks waiting to pass on the no overtaking ban in some stretches.
On the same thread…does a digi-card record the speed travelled…

do you mean distance travelled? if so yes

Speed trace for last 24 hr if I remember rightly

That is correct, after I was slightly politely put right last year, the next generation ones will record all speed apparently.

I better learn how to control over run then

I’m sure the Forrest road from Bordeaux to irun is no overtaking now for the whole length of it,and 80k’s for all trucks not just ADR,that was around 5 months ago.

You can’t be prosecuted for speeding on a chart but you may use it in your defence actually.
the speed trace has been used a number of times that i know of by the TC where they have gone into a firm for a taco check and found that the trucks have been speeding from the operating centre!
if your yard is 40 miles from the m way and the truck has been sat at 56 mph!! this has caused far more problems for the operator than a simple fine given to a driver by a copper
i never bother about the speed trace much but try to keep the hrs and breaks in order

The TC may take action in a case like this but you won’t be done for speeding and given points.
so if were to be doing about 75-80 then over here you won’t be done for it??

No the Driver Card doesn’t hold a record of speed travelled apart from over-speeds, but the digital tachograph head holds the speed for each second of vehicle movements for a total of 24 hours of vehicle movements.
I believe later tachograph models may keep a record of speed for a longer period than 24 hours of vehicle movements but I’m not sure if they’ve been introduced yet.
I got my answer…the question was asked because the old tachos would/could show a speed trace for any particular day...so wanted to know whether a digi holds that information..suppose you get flashed by a camera when you know you wasnt speeding ( not that i was ) just wanted to know whether we had some kind of back up..and yes we do..well done boys and girls..im proud of ya.

The speed data in the tachograph head starts to be over-written when 24 hours of vehicle movements are recorded, so unless you see the camera flash and are in a position to have the data downloaded within a few days it probably wouldn’t be any good to you, by the time the NIP arrives the speed data in the tachograph head is likely to have been over-written.

AFAIR it was up to 2.5% over-read and by law, no speedo or tachograph, whether private car or commercial vehicle can underread so if you’re doing 100km/h actual speed it is completely illegal for a tacho or a speedo to indicate even 99km/h.

What do you mean it dose not prove where you are; they have evidence you where there on a time and date
Yes you can use you digital or analog tachograph as proof
As the speed camera will have photos of you registration plate to prove you where there

Show me a pic of a tacho or tacho printout that shows what road you are travelling on.
They show your speed and time but not location, you could have been on a private road for all they know.
Speed cameras will have serial numbers or such like showing where they are positoned.
Courts need to prove beyond reasonable doubt, a copper saying you might have been travelling down a 40mph road at the time aint gonna cut it. If they were behind you and caught it on there camera then you are ■■■■■■ but if they pull you over 50 miles after you were speeding and find you have been doing 61mph then they cant prove where you were when you did it.
