Moved aimlessly around a vehicle (5)
I believe the answer is:
moped
I believe this clue is a double definition.
'moved aimlessly' is the first definition.
(I've seen this before)
'a vehicle' is the second definition.
(moped is a kind of vehicle)
'around' is the link.
(Other definitions for moped that I've seen before include "Vehicle - sulked" , "means of transport" , "Two-wheeled vehicle" , "simple conveyance" , "Was miserable; a vehicle" .)
