Exchange rubbish vehicle (5)
I believe the answer is:
truck
This clue is a triple definition!
'exchange' is the first definition.
(I've seen this before)
'rubbish' is the second definition.
(thesaurus)
'vehicle' is the third definition.
(truck is a kind of vehicle)
(Other definitions for truck that I've seen before include "Bargain" , "trade" , "trolley" , "Vehicle (with which one has no dealings?)" , "Lorry - wagon" .)
