Driver's woe
I believe the answer is:
flat
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">driver's woe</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for flat that I've seen before include "Quarters - punctured - smooth" , "one or more in uniform" , "Pied-a-terre" , "Level - below the natural note" , "Prostrate" .)
