Stranded motorist's need (3)
I believe the answer is:
tow
'stranded motorist's need' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tow that I've seen before include "Pull along behind, say barge" , "Pull along (a vehicle)" , "Draw" , "Pull using cable" , "Drag along behind, say barge" .)
