If you approach an intersection at which the traffic light is NOT working, you must _________ before proceeding through the intersection.

Explanation

Under North Carolina law, if the traffic signal that you are approaching is not working, treat the intersection like an all-way stop (i.e., as if there were a stop sign at each approach to the intersection). That is, you must stop before entering the intersection, yield according to the right-of-way rules for all-way stops, and then proceed (with extreme caution) when it is safe to do so.
