am I right in saying, the same infringement cant be highlighted again once the card has been down loaded and the infringement brought to my attention 
It dependsā¦
When the card is downloaded, it will be downloaded into a raw format which usually takes the file extension of DDD or ESM. This raw data is then imported into whatever tacho management software you or your employers have chosen to use. If, for example, your company uses Software Brand A to analyse the data then this infringement will be highlighted but only the once because the analysis software will read the card to see whether any new data has been written to the card since it was last downloaded. If no new data has been written to the card then the analysis software will typically not bother to analyse it. If new data has been written to the card then typically the analysis software will import the new data.
Assuming you now take your drivers card and have it read to somewhere else and this company uses Software Brand B to analyse the data, the infringement will then show up again. The only way in which the infringement will not show up is when the day in question is overwritten by new data.
To give you some idea of how long this can take, I drive on average three times per week and on those three days, the mode probably changes twenty times. I am still waiting for my driving record for June 2012 to be overwritten!!
So any one know what happens when VOSA downloads your card and it flags up an infringement? They may deal with it with a warning which should be the end of it for that one.
But then you get stopped a few days later by VOSA, will it flag up as having being dealt with? Or could they decide to issue you a fine for it?
AIUI, nothing VOSA/your employer/the agency does when downloading data from your card will change the information held on your card at all - It is very much āRead Onlyā. So it follows that if anyone downloads data from your card several days, weeks or even months later it will have no effect at all on the status of any infringements that are recorded thereon. If your employer flags up the same infringement week after week, thereās not a lot you can do about it (but by the same token, it has no effect on the status of said infringement, other than wasting a few sheets of A4 and a small amount of printer ink).
But if VOSA notice an infringement and deal with same (whether it be by āwords of adviceā, fixed penalty or prosecution) then this will be recorded on their computer database. It wonāt affect the data on your card, but the information regarding the earlier disposal will be noted on their system, and will be visible to the VOSA inspector should you be stopped again in the ensuing days/weeks/months. Not sure what the situation would be if you got stopped elsewhere in Euroland though - anyone know?
Donāt they write some kind of note on it saying it has been dealt with?
Vosa canāt do you for the same infringement twice if thatās what you mean.
