A course for non-drivers (8)
I believe the answer is:
footpath
'a course' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for footpath that I've seen before include "It's at the side of the road for pedestrians" , "Way for pedestrians beside road" , "cross-country route" , "Walker's track, pavement" , "means of access?" .)
