Hole, after reversing, crossed by a street vehicle (9)
I believe the answer is:
aeroplane
'vehicle' is the definition.
(aeroplane is a kind of vehicle)
'hole after reversing crossed by a street' is the wordplay.
'hole' becomes 'pore' (pore is a kind of hole).
'after reversing' says the letters should be written in reverse.
'crossed by' indicates putting letters inside (inserted letters are crossed or covered by others).
'street' becomes 'lane'.
'pore' backwards is 'erop'.
'a'+'lane'='alane'
'erop' going within 'alane' is 'AEROPLANE'.
(Other definitions for aeroplane that I've seen before include "Flying vehicle" , "What taxis" , "Flying craft" , "Flier" , "Spitfire, for example" .)
