Pop quiz! (Because everyone loves spontaneous tests of driving knowledge, right?)
It’s a stormy day and you approach a flashing red light while driving. As you get closer, it becomes clear it’s a traffic light controlled four-way intersection with a power outage or other mechanical failure. No yellow or green — just red lights flashing in all directions. You…
- A) Thank the electricity gods because you’re running late for a very important date, then step on the gas.
- B) Approach the intersection slowly and stop only if you see another vehicle approach.
- C) Curse the electricity gods, come to a complete stop, and wait for the power to come back on, giving you the green light to proceed.
- D) None of the above.
The answer is… D.
Options A) through C) aren’t only ridiculous, they’re dangerous and against the law. And yet, we’ve seen confused drivers approach intersections controlled by traffic signals in similar ways during power outages. Confusion at intersections can cause chaos, which can lead to serious “T-bone” collisions.
What To Do When Traffic Signals Aren’t Working
In a nutshell: treat the intersection like a four-way stop.
- The first vehicle to come to a complete stop at the intersection goes first;
- If two vehicles arrive and stop at the same time, the one on the right goes first;
- If two vehicles stop at the intersection at about the same time and are facing each other, the one making a left turn yields to the one going straight through. Otherwise, both vehicles proceed straight through at the same time.
- In all cases, yield to pedestrians.
- Before entering the intersection, be sure other approaching vehicles are following the rules and coming to a complete stop.
Inoperative traffic signals caused by a power outage usually show themselves as flashing red lights from backup power, which lasts a maximum eight hours. Signals will go completely dark if hydro isn’t restored during that time. So, keep that in mind if you ever approach a traffic signal controlled intersection with no lights working at all, and treat it like a four-way stop.

And remember, it’s never up to the electricity gods – only you have the power to get through intersections safely when the power goes out.
