Late transport (6)
I believe the answer is:
hearse
'transport' is the definition.
(hearse is a kind of transport)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for hearse that I've seen before include "Last time transport" , "Vehicle for one's last journey" , "Car for carrying a coffin" , "Vehicle bearing coffin" , "Undertaker's car" .)
