Break down in Cairo traffic (3)

I believe the answer is:

rot

'break down' is the definition.
(thesaurus)

'in cairo traffic' is the wordplay.
'in' says the answer is hidden in the clue.
'ROT' can be found hidden inside 'cairo traffic'.

(Other definitions for rot that I've seen before include "Rhubarb" , "Deteriorate" , "Decay, moulder" , "Decay - rubbish" , "Cobblers" .)

I've seen this clue in The Times.
