Bend makes car crash (3)
I believe the answer is:
arc
'bend' is the definition.
(arc can mean to curve or bend)
'car crash' is the wordplay.
'crash' indicates anagramming the letters.
'car' anagrammed gives 'ARC'.
'makes' acts as a link.
(Other definitions for arc that I've seen before include "section of Circle Line" , "A curve for Joan of . . ." , "Luminous electrical discharge" , "Curved part of circle" , "be rapidly discharged" .)
