Wrongly report the condition of a major road (8)
I believe the answer is:
misstate
'condition of a major road' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their base form.
Perhaps you can see a link between them that I don't see?
'wrongly report' is the wordplay.
'wrongly' becomes 'mis' (I can't explain this - if you can you should give a lot more credence to this answer).
'report' becomes 'state'.
'mis'+'state'='MISSTATE'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for misstate that I've seen before include "Put incorrectly" , "Inaccurately report" , "Declare wrongly" , "Wrongly announce" , "Give inaccurate info" .)
