At an intersection whose traffic signals are NOT working, you must _________ before proceeding through the intersection.

Explanation

In Alabama, if the traffic signals at an intersection are not working, you must 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 stop signs, and then proceed (with extreme caution) when it is safe to do so.
