I believe the answer is:
logbook
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">vehicle registration document</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for logbook that I've seen before include "Vehicle registration document" , "official record" , "Former vehicle document" , "Car owner's document" , "Ship's record" .)
