Called after parking accident (5)
I believe the answer is:
Here is my best explanation:
'accident' is the definition.
'called after parking' is the subsidiary indication.
'called' becomes 'rang' ('ring' can be a synonym of 'call').
'after' says to put letters next to each other.
'parking' becomes 'p'.
'rang' put after 'p' is 'prang'.
(Other definitions for prang that I've seen before include "nasty collision", "Crash (informal)", "Plane or car crash", "Crash (a car, aircraft) (colloq.)", "Minor accident", "Car accident, usually not too serious", "Crash (slang)", "Car crash", "Crash (a motor vehicle)" and "Crash involving a car".)
