Vespa vehicle (7)
I believe the answer is:
scooter
'vespa vehicle' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scooter that I've seen before include "To score (anag)" , "Large diving duck" , "Traveller" , "Wheeled board with steering handle" , "Motorised bike" .)
