Parking neatly when hammered? Fine, sometimes (7)
I believe the answer is:
penalty
'fine sometimes' is the definition.
I can't tell whether this defines the answer.
'parking neatly when hammered?' is the wordplay.
'parking' becomes 'p' (abbreviation on road signs).
'when hammered?' is an anagram indicator (I've seen 'when hammered' mean this (letters beaten into a new form)).
'neatly' with letters rearranged gives 'enalty'.
'p'+'enalty'='PENALTY'
Can you help me to learn more?
(Other definitions for penalty that I've seen before include "Fine - handicap" , "Perhaps fine" , "Disadvantage imposed" , "Spot kick" , "Punishment for error (in game)" .)
