In Europe and some other countries, there is an agreement on the regime of work and rest of drivers (AETR). Drivers' work and rest regimes are monitored using special devices - tachographs. I have two questions on this topic:

1 How is the process of recording and storing information in a digital tachograph regulated? Who controls this process? Ministry of transportation? Workshops that set up digital tachographs? I would be very grateful to you for an answer to this question and for links to regulatory documents on this issue.

2 How is the account of the work of the masters of setting up digital tachographs kept? On paper or in electronic form? I would be very grateful to you for an answer to this question and for links to regulatory documents on this issue.

I would be grateful for any information on these issues in your country or other countries.
