Minor accident: made call after parking (5)
I believe the answer is:
prang
'minor accident' is the definition.
(I've seen this before)
'made call after parking' is the wordplay.
'made call' becomes 'rang' (called by phone).
'after' says to put letters next to each other.
'parking' becomes 'p' (abbreviation on road signs).
'rang' put after 'p' is 'PRANG'.
(Other definitions for prang that I've seen before include "Crash involving a car" , "Crash (a motor vehicle)" , "nasty collision" , "knock" , "Popularly, a motoring contretemps" .)
