Screens beer as driver’s concern? (5,4)
I believe the answer is:
blind spot
'driver's concern?' is the definition.
(I've seen this in another clue)
'screens beer' is the wordplay.
'screens' becomes 'blinds' ('blind' can be a synonym of 'screen').
'beer' becomes 'pot' (pub name for large glass of beer in Australia).
'blinds'+'pot'='BLIND SPOT'
'as' acts as a link.
(Other definitions for blind spot that I've seen before include "Unseen area of road" , "where one cannot see" , "Area where understanding is lacking or one is unsighted" , "source of misunderstanding?" , "Hazard for driver" .)
