'driving' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'force' is the wordplay.
I cannot quite see how this works, but
'force' could be 'police' (police is a kind of force) and 'police' is found in the answer.
The remaining letters 'traffic' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
