Parade vehicle (5)
I believe the answer is:
float
'parade vehicle' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for float that I've seen before include "Not sink" , "Soft drink with a scoop of ice cream - rest on water - electric cart" , "Levitate" , "cash in hand" , "Stay on the surface without sinking" .)
