Steal a free ride (4)
I believe the answer is:
lift
This clue is a double definition.
'steal' is the first definition.
(I know that lift is a more specific form of the action steal)
'a free ride' is the second definition.
(as in a lift in someone's car)
(Other definitions for lift that I've seen before include "Raise - shot in the arm" , "Raise - hoist" , "It's an elevator in USA" , "Raise; elevator" , "Means of access to different floors" .)
