Total hours on tachgraph

hi can you help me with this i only passed my test in march.on two days of the week you can work a 10 hour day does this include breaks loading/unloading
and poa.

so the tachograph can not show more then 10 hours from start
till finish.

On two days a week you can DRIVE a maximum of 10 hours, your shift could be up to 15 hours, provided you still have a 9 hour daily rest available to you, with other work, POA and breaks. If you do not have a 9 hour daily rest available than the shift could be up to 13 hours, including the 10 hours driving.
