thus recording no information whatsoever. There is also "forgetting to insert" the chart when beginning duty. Unauthorized changing of the discs (and then discarding one of the two, so that some activities are "forgotten") is well known throughout Europe. "Ghosting" is another common trick when false driver information is entered onto a second chart to give the appearance that there is a second driver present in the cab for long-distance runs that cannot be completed within a single driver's daily driving period. Digital tachographs Introduction of the digital tachograph in the EU Digital tachographs make tampering much more difficult by sending signals in an encrypted manner. EU regulation 1360/2002 makes digital tachographs mandatory for all vehicles described in the above section Regulations and manufactured after 1 August 2005. Digital tachographs have been required as of 1 May 2006 for all new vehicles for which EWG regulation VO(EWG)3820/85 applies, as was published in the official newsletter of the European Union L102 from 11 April 2006. Digital tachographs have been implemented in Mexico since 1994, but this is not a federal regulation. The last implementations developed in Mexico have GPS capabilities such as mapping, altitude and location-activated video triggering.
