Drive a car around trees (5)
I believe the answer is:
steer
'drive a car' is the definition.
'around trees' is the wordplay.
'around' indicates an anagram.
'trees' with letters rearranged gives 'STEER'.
(Other definitions for steer that I've seen before include "Con" , "Drive - young ox" , "Guide; bullock" , "Reset so as to direct" , "Direct; young ox" .)
