Man behind slow vehicle (6)


I believe the answer is:

'slow vehicle' is the definition.
(vehicle which moves slowly in a funeral procession)

'man behind' is the wordplay.
'man' becomes 'he'.
'behind' becomes 'arse' (synonyms).

(Other definitions for hearse that I've seen before include "Vehicle for carrying a coffin", "Car for carrying a coffin", "Undertaker's car", "Carriage for a coffin", "Funeral vehicle".)

I've seen this clue in The Guardian.
