Car going around curve (3)
I believe the answer is:
arc
'curve' is the definition.
(arc is a kind of curve)
'car going around' is the wordplay.
'going around' is an anagram indicator.
'car' anagrammed gives 'ARC'.
(Other definitions for arc that I've seen before include "Electrical spark" , "bends?" , "part of turning circle?" , "section of Circle Line" , "Half-moon" .)
