Reduced break.
Started today at 04.40.
What time can I work until?
Thanks
You should be finished work by:
19:40 if you have another reduced daily rest period available.
17:40 if you do not have a reduced daily rest period available.
19:40 if you’ve managed to have 3 consecutive hours rest during the shift.
Thanks Tacho, 3 is the max in a2 week period right?
You can have 3 reduced daily rest periods between weekly rest periods.
Lets say you started work on Sunday after a weekly rest period, you had a reduced daily rest period Sunday so you can have 2 more before your next weekly rest period.
It doesn’t matter what part of the week you have your weekly rest periods, it’s 3 reduced daily rest periods between 2 weekly rest periods.
Great, thanks so much for the quick reply. I started this working week yesterday. I had a weekly rest period on Fri and Sat so last night was my first reduced daily rest period after a weekly rest period.
I’m getting confused as the truck timer app I use to record my hours is saying I need to stop at 17.40.
Thanks again.
You can legally have:
3 reduced daily rest periods between weekly rest periods.
2 extended driving days (10 hour drives) each week (00:00 Monday to 24:00 Sunday).
You can drive for a maximum of 56 hours in a week.
You can drive for a maximum of 90 hours in each 2 week period
It would have been simpler if everything was calculated between weekly rest periods, but who knows why the regulations were written the way they are 
I’ve no idea why a truck timer app would say you need to stop at 17:40, you have reduced daily rest periods available and you can’t possibly have reached your maximum weekly/fortnightly driving limit, so assuming that your daily driving limit is OK I’ve no idea about that 
Thanks for taking the time to reply so thoroughly.
I had a look at the timer app log and I had wrongly recorded the weekly rest as daily rest and so had no reduced rests left available today. I changed the log file to weekly rest and it showed I had until 19.40 before a daily rest.
At the end of day I was being a muppet.
Hi could you tell me which app you was using?
Cheers
Yes its called Trucker Timer. It cost £3 odd on Google Play for android. Not sure about iphone, probably the same.
