Car crashed at bend (3)
I believe the answer is:
arc
'bend' is the definition.
(arc can mean to curve or bend)
'car crashed' is the wordplay.
'crashed' indicates an anagram.
'car' with letters rearranged gives 'ARC'.
'at' is the link.
(Other definitions for arc that I've seen before include "Part of a circle's circumference" , "Something curved in shape" , "circle, partly" , "Segment of circumference" , "Semi-circle" .)
