The (legally correct) approach would be to set the tacho to whatever mode fits with the situation at the point you leave the cab to hand the keys in, then if necessary do a handwritten entry once you are able to return to the cab to correct any incorrectly recorded activity.But (almost) no-one ever does that…
…most would drivers would picture trying to explain this to a TM who is proffering pieces of paper to sign and realise that it wouldn’t matter what words came out of your mouth or handwritten notes were provided, the TM would just require the infringements to be signed for.
