Notice the traffic light's against you and get furious (3,3)
I believe the answer is:
see red
'get furious' is the definition.
(I've seen this before)
'notice the traffic light's against you' is the wordplay.
I cannot quite understand how this works, but
'notice' could be 'see' (notice can mean to spot or see) and 'see' is found within the answer.
'light' could be 'red' (red light is a kind of light) and 'red' is found in the answer.
No letters remain.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for see red that I've seen before include "Burst a blood vessel" , "Be suddenly angry, as bull might" , "Lose one's temper" , "Become enraged" , "Lose temper like enraged bull" .)
