Looked into wrong sign always blocking road (1,5)
I believe the answer is:
x-rayed
'looked into' is the definition.
'wrong sign always blocking road' is the wordplay.
'wrong sign' becomes 'x' (x is used to show an incorrect answer).
'always' becomes 'aye' (I've seen this before).
'blocking' means one lot of letters goes inside another.
'road' becomes 'rd' (abbreviation).
'aye' placed inside 'rd' is 'rayed'.
'x'+'rayed'='X-RAYED'
(Other definitions for x-rayed that I've seen before include "Medically photographed" , "Photographed using radiation" .)
