Could be worse - not a road-hog (8)
I believe the answer is:
passable
'worse not a road-hog' is the definition.
I can't tell whether this defines the answer.
'could be' is the wordplay.
I cannot quite see how this works, but
'be' could be 'pass' (passing is a kind of being) and 'pass' is found within the answer.
The remaining letters 'able' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for passable that I've seen before include "okay?" , "Good enough to be acceptable" , "not hogging the road" , "All right" , "Fair" .)
