Where traffic lights were dark, drivers treated the intersections as four-way stops.
Good job, North Carolinians.
My local experience has been that when traffic lights are dark, drivers – who have a questionable understanding of “traffic takes turns a car at a time in clockwise order at a stop sign”, much less “treat a flashing red signal as a stop sign”, much less “treat an out traffic signal as a stop sign” – just enter a state of total confusion and start randomly driving however.
The thing says “video unavailable” for me, but this YouTube video from Associated Press seems to have at least the same frame shown in the thumbnail:
