How to do if 2 or more Driver driving across Europe 
do what exactly?
I would assume he is talking about tacho modes?
just an inkiling.
maybe iām totally wrong 
If you mean double man teams.
9 hours rest
9 hours driving each, can still be extended to 10 hours twice per week
Vehicles manned by two or more drivers are governed by the same rules that apply to single-manned vehicles, apart from the daily rest requirements.
Where a vehicle is manned by two or more drivers, each driver must have a daily rest period of at least 9 consecutive hours within the 30-hour period that starts at the end of the last daily or weekly rest period.
