little help required please, if i only drive 5 /6hrs a day in 5 day week i do 27hr wk driving plus installs, so can i still do p/js for the other 18hrs, or does that say after my working week even if only 27hrs driving &18hrs of installs over the week i still have to take a 48hr rest, even though not reached drivers hrs… silly question maybe just looking for honest ans cheers weeman 
You must begin a new weekly rest no later than 144 hours after you finished your last one. How many hours you have actually driven while working has no bearing on that.
A weekly rest is 45 hours, not 48.
cheers for your info, in these tough times just find meself trying to use up my driving hrs to make more £ $, if poss,
