Roadside area (3-2)
I believe the answer is:
lay-by
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">roadside area</span>' is the definition.<br/ ><span class="explanation-format__explanation">(area by the side of a road)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for lay-by that I've seen before include "Off-road stopping place" , "Stopping-place" , "Area where drivers can pull over" , "Drivers' pull-in" , "Roadside parking place" .)
