Dancing bishop leaves one stretched out on the road (4)
I believe the answer is:
limo
'one stretched out on the road' is the definition.
(as in a stretch limousine)
'dancing bishop leaves' is the wordplay.
'dancing' becomes 'limbo' (limbo is a type of dance).
'bishop' becomes 'B' (chess abbreviation).
'leaves' indicates named letters should be taken away.
'limbo' with 'b' taken out is 'LIMO'.
(Other definitions for limo that I've seen before include "Set of rooms" , "Stretched car, often used for partying" , "Luxury car" , "Large luxurious car" , "Long motor" .)
