Far away, referring to car test, English (6)
I believe the answer is:
remote
'far away' is the definition.
(I've seen this before)
'referring to car test english' is the wordplay.
'referring to' becomes 're' ('re' means regarding or about).
'car test' becomes 'MOT'.
'english' becomes 'E' (abbreviation).
're'+'mot'+'e'='REMOTE'
(Other definitions for remote that I've seen before include "Far-off" , "Distant - meteor (anag)" , "Distant, far away" , "as from armchair to TV?" , "Detached" .)
