Turned rickety car in front of drive (6)
I believe the answer is:
rancid
'turned' is the definition.
(I've seen this before)
'rickety car in front of drive' is the wordplay.
'rickety' indicates anagramming the letters.
'front of' suggests taking the first letters.
The first letter of 'drive' is 'd'.
'car'+'in'='carin'
'carin' anagrammed gives 'ranci'.
'ranci'+'d'='RANCID'
(Other definitions for rancid that I've seen before include "Smelly and going bad" , "(Of fatty foods) gone off" , "Fetid" , "(Of fatty foods) stale" , "Stale, rank" .)
