Satisfaction from parking on trip (5)
I believe the answer is:
pride
'satisfaction' is the definition.
(I know that pride is a type of satisfaction)
'parking on trip' is the wordplay.
'parking' becomes 'p' (abbreviation on road signs).
'on' is a charade indicator (letters next to each other).
'trip' becomes 'ride' (eg a trip in a car).
'p'+'ride'='PRIDE'
'from' is the link.
(Other definitions for pride that I've seen before include "Leonine family" , "big cats" , "cause of swelling?" , "Group of lions" , "Hubris" .)
