Doesnât matter, it might be a breach of the WTD but where is the tacho infringement?
You did 3 hours and 15 minutes of driving, and then 3 hours and 15 minutes of either POA or other work. Thatâs legal.
If Iâm reading your post right then you shouldnât have anything to worry about.
You havenât reached 4.5 hours driving so donât need to show 45 mins of âbreakâ.
The time spent on POA while in the passenger seat means you wonât have exceeded 6 hours âworkâ either.
Assuming you were simply being driven back rather than assisting the other driver with deliveries etc, then I see no reason to record any âother workâ on your card.
Legal.
I did it double manning earlier this year, and did exactly what you have described, and havenât been notified of any infringements off our agencyâs high profile customer.
Ken.
Itâs not double manning itâs what I believe is called a âshuntâ. As long as you havenât exceeded your 4.5 hour driving limit or your 15 spread I canât see a problem.
If your records are analysed by an analysis company Iâm not sure that they would know that you were not double manning so you probably wouldnât get an infringement off the company either way.
If you were stopped by VOSA would they know that you were not double manning unless you told them, I doubt it.
Having said that, as others have said it doesnât look like youâve done anything wrong anyway so itâs all academic really.
Youâre not double manning anyway - Youâre on âother workâ whilst being driven back by the other guy. No need to even put your tacho in and hit the â2â button.
You were never going to drive this vehicle right?
Manual entry is âother workâ rather than POA, as you are not free to do anything but be your driverâs captive audience for the duration. If it is night time, youâre not even free to âread a newspaperâ so donât use POA if you want to really be squeaky clean here! 
Basically you could drive for 4 hours 29 minutes and then spend the next 10 hours 31 minutes doing other work and although that would be a breach of the Working Time Directive, it would be 100% tachograph legal.
You couldnât do 4 hours 30 minutes and do 10 hours 30 minutes other work though because as soon as youâve completed 4 hours 30 minutes of driving you MUST take a break and cannot do any other work until you have.
Thanks for all the replies.
I just try to keep as clean as possible whether its Tacho regs or WTD.
Iâve recently started a new job and donât want any excuse for them to look at my probationary period again.
a friend of mine was taken off normal duty last week, asked to deliver a unit and trailer and get a lift back in a wagon with another driver. I 
) did and am now worried about getting an infringement. I was not double manning as my card didnât go in in the first hour of duty for the other driver and wagon. But of course my tacho will be recording me as no.2 driver and putting my time down as POA.
