Where is the Missing Mileage report?
The “Missing Mileage” report can be found in OPTAC3 under “Reports” and “Vehicle Reports”. This report is for vehicles fitted with analogue tachographs only.
The equivalent report for vehicles fitted with digital tachographs is called “Unknown Driver”. This report is also located under “Reports” and “Vehicle Reports”.
In the Unknown Driver report, select the option “Show driver(s) before and after unknown driving periods” to display the distance that the vehicle has travelled without a driver’s card inserted in the tachograph. The report will group together the unknown driving times and then display the “missing mileage” – the distance is the difference in the odometers from the last driver’s card extraction and next driver’s card insertion.
