Phoned following parking accident (5)
I believe the answer is:
prang
'accident' is the definition.
(I've seen this before)
'phoned following parking' is the wordplay.
'phoned' becomes 'rang' ('ring' can be a synonym of 'phone').
'following' means one lot of letters go next to another.
'parking' becomes 'p'.
'rang' after 'p' is 'PRANG'.
(Other definitions for prang that I've seen before include "Crash (a car, aircraft) (colloq.)" , "Possible argument with van" , "nasty collision" , "Plane or car crash" , "Car accident, usually not too serious" .)
