It should have a lane to itself (3)
I believe the answer is:
bus
'it should have a lane to itself' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for bus that I've seen before include "Motor-coach" , "eg Double-decker" , "Something caught" , "Means of public transport" , "People carrier" .)
