If the digicard hasn’t been used since that shift, it might not be an infringement, if they remembered another 15min break and a little other work before daily / weekly rest, when the manual entry is made.
On the other hand if they didn’t have another 15 break, as stated above, would be a wtd infringement.
Way I think it works as said shift upto 6 hrs need 15 mins break over 6 hours need a second 15 mins. Say you work 4 hrs take 15 then work 3 hours and done for the day taking your week daily rest.
It thinks you’ve worked 7 hours only had 15 mins break as it can’t tell recognise you as having a weekly rest and or a break
So basically if happens what do before you finish take another 15 mins break change tacho to bit of other work for couple mins then back to rest for your daily rest.
If you have a 15 minute break from 11:45 to 12:00 you can then work until 18:00 before needing another break for the working time regulations 6 hour rule.
That is of course assuming you don’t reach 41/2 hours driving time.
It’s just on the odd occasion when I, I mean my friend, only does six hours there is no need for a break at all, as long has he hasn’t exceeded four and a half hours driving, but some advice says 15 minutes for six hours work, (which is not strictly true) then 30 minutes for six to nine hours work, which is a bit confusing.
