Criminal with ridiculous speed on dodgy road (9)
I believe the answer is:
desperado
'criminal' is the definition.
(desperado can mean a criminal or outlaw)
'ridiculous speed on dodgy road' is the wordplay.
'ridiculous' indicates anagramming the letters.
'on' says to put letters next to each other.
'dodgy' is an anagram indicator (a dodgy or wrong order of the letters).
'speed' anagrammed gives 'despe'.
'road' with letters rearranged gives 'rado'.
'despe'+'rado'='DESPERADO'
'with' is the link.
(Other definitions for desperado that I've seen before include "Road speed (anag.)" , "reckless one" , "Bandit, outlaw" , "reckless type" , "Reckless outlaw" .)
