Auto for hire (3)
I believe the answer is:
cab
'auto for hire' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cab that I've seen before include "Taxi to hold an engine-driver" , "vehicle" , "'The authority collects money made from crime, initially (3)'" , "Transport" , "A taxi in New York" .)
