Take to the impound lot (3)
I believe the answer is:
tow
'take to the impound lot' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tow that I've seen before include "Pull along (a vehicle)" , "form of flax" , "Pull along behind, say barge" , "Draw" , "Tug" .)
