Striking car, admit to crash (8)
I believe the answer is:
dramatic
'striking' is the definition.
(I know this)
'car admit to crash' is the wordplay.
'to crash' indicates an anagram.
'car'+'admit'='caradmit'
'caradmit' anagrammed gives 'DRAMATIC'.
(Other definitions for dramatic that I've seen before include "Substantial" , "Sudden and striking" , "Like play" , "Histrionic" , "Thrilling in effect" .)
