Renegade's terrible speed approaching rough road (9)
I believe the answer is:
desperado
'renegade's' is the definition.
(both can mean a rogue or outlaw)
'terrible speed approaching rough road' is the wordplay.
'terrible' indicates an anagram.
'approaching' is a charade indicator (letters next to each other).
'rough' is an anagram indicator (a rough or broken ordering of the letters).
'speed' anagrammed gives 'despe'.
'road' with letters rearranged gives 'rado'.
'despe'+'rado'='DESPERADO'
(Other definitions for desperado that I've seen before include "Reckless guy" , "Reckless criminal" , "Road speed (anag.)" , "reckless type" , "Reckless outlaw" .)
