Went on the radio with opinion representing driver's need (4,5)
I believe the answer is:
road sense
'need' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for road sense that I've seen before include "best practice" , "Driving schools teach this" , "Driver should display this" , "Driving skill" , "Driver's good judgment" .)
