Praise former road charge? Not entirely! (5)
I believe the answer is:
Here is my best explanation:
'praise' is the definition.
(extolling is a kind of praising)
'former road charge? not entirely' is the wordplay.
'former' becomes 'ex'.
'road charge?' becomes 'toll' (I've seen this before).
'not entirely' means to remove the last letter.
'toll' with its final letter taken off is 'tol'.
