Vehicle on the move delivers seed (7)
I believe the answer is:
caraway
'seed' is the definition.
(caraway seed is a kind of seed)
'vehicle on the move' is the wordplay.
'vehicle' becomes 'car' (car is a kind of vehicle).
'on the move' becomes 'away'.
'car'+'away'='CARAWAY'
'delivers' is the link.
(Other definitions for caraway that I've seen before include "Umbelliferous plant" , "____ seeds, for cooking" , "Seed used as flavouring" , "Oil taken from it" , "Seeds used for flavouring" .)
