agency job tomorrow

Hey guys. Some of you might know i started with agency last wednsday only thursday and friday work. Which isnt good enough. Anyway just wanted to know since i only worked 19hrs those to days. Only drove 6hrs somthing on friday because i was in a sprinter box van in the tacograph read 6hrs somthing. I must check my printout exactly. And way do i take away those 6hrs from the 90hrs driving in a the 2nd week? Since i only started last thursday. On thursday i was driving van so didnt need tacograph. Another thing… i mite not have to use tacograph someone told me on this site because its 3.5ton if i remember. Cheers guys :smiley:
