Satisfaction from parking vehicle (5)
I believe the answer is:
pride
'satisfaction' is the definition.
(I know that pride is a type of satisfaction)
'parking vehicle' is the wordplay.
'parking' becomes 'p' (abbreviation on road signs).
'vehicle' becomes 'ride'.
'p'+'ride'='PRIDE'
'from' acts as a link.
(Other definitions for pride that I've seen before include "''. . . . . goeth before a fall''" , "conceit" , "Hubris" , "Leonine family" , "big cats" .)
