No. Creating an Attestation of Activities does not write, update, or transfer any information to the driver's card or the tachograph.
The attestation is a separate supporting document used to explain periods that are not recorded by the tachograph, such as annual leave, sick leave, other work, periods of availability, or driving a vehicle exempt from the EU drivers' hours rules.
After completing the form, print the document and ensure it is signed by both the company representative and the driver before the journey. The signed original should be kept with the driver's tachograph records and presented during a roadside inspection if requested.
This document supplements tachograph records—it does not replace or modify them.
