It's not one of the listed ways you can get Steak'n'Shake chili, as far as I can tell -- they have chili three way and five ways, but four? Forget that!*
No, four-way is what a failed stoplight devolves to: if the light is out, absent other signage or someone directing traffic, the intersection becomes a four-way stop. There are no significant exceptions to this rule.
From my workplace, one of the city's major intersections is readily visible. During rush hour (which runs from about four to six-thirty p.m., a long hour), the traffic light failed: power was out. Our lights were flickering, but we have a big UPS and a generator; about all that happens is the lights blink, the vending machines go off and on, and our internet connectivity becomes variable-- Yeah, that last will be looked into today; it shouldn't happen.
But this isn't about my office's lack of cute pet videos. It's about what people did at a high-traffic, multilane intersection. It wasn't pretty. There were lots of near-misses, though no actual crashes. People were zooming though as if the lack of a light meant "do your own thing!" There were the ones who didn't even slow down, the rolling stops, the swerves and unsignaled turns; there were people sitting stopped for turn after turn, trying to understand it all. There were even a few drivers who stopped their cars in the intersection!
That's not how this works. That's not how any of this works. It's a question on the driving exam and the answer is, when the traffic light goes out, the intersection is to be treated as a four-way stop.
* However, Skyline Chili will fix you right up for four-way chili -- they have two different kinds of four-ways. Which is confusing.
