Traffic lights you can't go through

Ross

I believe the answer is:

reds

(Other definitions for reds that I've seen before include "Colourful communists" , "Scarlet and crimson, say" , "First snooker balls to be potted" , "These are not right" , "Tidies up" .)

I've seen this clue in The New York Times.
