Drivers pass through it for a change (7)
I believe the answer is:
neutral
'a change' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'drivers pass through it' is the wordplay.
I cannot really see how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is present in the answer.
The remaining letters 'neural' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for neutral that I've seen before include "Impartial, non-aligned" , "Unaligned" , "Inoffensive; beige colour" , "Not partisan or supporting either side in dispute" , "Not favouring one side or the other" .)
