Bad drivers rowed loudly - silence shrouding journey the other way (4,4)
I believe the answer is:
road hogs
'bad drivers' is the definition.
(road hog can mean a selfish driver)
'rowed loudly silence shrouding journey the other way' is the wordplay.
I cannot really understand how this works, but
'way' could be 'road' (road is a kind of way) and 'road' is present in the answer.
The remaining letters 'hogs' 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?
(Another definition for road hogs that I've seen is " Impatient and intemperate drivers".)
