On analog tachographs equipped to measure engine revolutions per minute (rpm), on which side of the chart disc is this data recorded?

Question

DentroTest · Accepted Answer

On analog tachographs that also record engine revolutions per minute, that data is traced on the back of the chart disc. The front holds the speed, the driver's activity times (driving, other work, availability, breaks and rests) and the distance traveled, which are the records required by the tachograph regulation (Annex I of Regulation (EU) 165/2014). Therefore, the revolutions are not recorded on the front or on either side without distinction.
