Where cars run the book by Kerouac (2,3,4)
I believe the answer is:
on the road
'book by kerouac' is the definition.
'on the road' can be an answer for 'book' (I've seen this before). I'm not certain of the 'by kerouac' bit.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for on the road that I've seen before include "Jack Kerouac novel" , "Book" , "as a commercial traveller?" , "In the Fifties, a novel" , "way to travel" .)
