I believe the answer is:
learner
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">unqualified driver</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 learner that I've seen before include "One with an L-plate" , "One under tuition" , "Scholar - novice" , "Student (of driving?)" , "who needs plates" .)
