It seems many of the most entertaining videos on the internet started as dashcam footage out of Russia. Whether it’s truck drivers miraculously thrown through their windshields and casually walking away or actual meteor strikes, it seems like Russian dashcams have captured it all. Rumor has it that insurance fraud is so common there, dashcams have become standard accessories on all cars. And I’m grateful for that: without them, we’d have no footage of the great sewage truck implosion of 2016.

In the video [embedded below], a driver with his radio blasting pulls up to an intersection. He idles to a stop behind a taxi and next to a bus, parked further ahead is an orange tanker truck. Just as the pop song on his radio hits a beat, the tanker implodes, its metal sides blow out, and it covers the intersection in brown sludge.

That’s right, the bus, the nearby cars, and the road are all sprayed down with the tanker’s…contents.

One of my favorite aspects of the video is everyone’s reaction. You would think the driver of a white hatchback, coated with the worst of the spill, would stop and confront the truck driver. In a place like the U.S., there might be some compensation for such an unfortunate incident. But not in Russia. When the light turns green, the white car takes off, seemingly deciding to just hose the mess off later.

Then there’s the driver filming the entire incident. He just chuckles and comments the entire time. I don’t speak Russian. But there’s certainly never a “Holy crap!” like I would have uttered. He seems amused by the entire thing as he fords the floating feces to navigate the flooded intersection. Does this happen often in Russia?

So what went down? The comments on the viral YouTube video below give us some clues.

First and foremost, why would a truck implode? You can clearly see the metal sides of the tank collapsing inward. One commenter asked point blank, “So there was low air pressure inside the tank in comparison to the outside? What caused air to be sucked out of the interior of the tank?” Someone else explained, “Someone left the pump on. So while they were driving it was continuously lowering the pressure in the tank. Once the differential was high enough, it sucked the seal into the tank, after that it just leaks out.”

Yet another commenter disagreed: “I used to drive one of these trucks. Rust along the seams on the inside played a factor. It was still compressed from his last job. These tanks are built heavy-duty like submarines. He would’ve known if the pump was still going, it wouldn’t have made it over 5 mph with the pump still going without throwing his PTO shaft.”

I’m not entirely sure what caused the accident. But I’m here to say it wasn’t just slowly leaking through some rusty seam. That was an explosion!

So was this truly a sewage truck? Again, the internet seems divided. Some commenters insist it was, and the flooding seems to have the correct…consistency. But one commenter said, “This is not a septic truck, it’s a hydro excavation tank used in directional drilling applications and exposing underground utilities.” Another said, “That’s not a poop truck. That’s a mud truck used in ditch digging.” But of course, some armchair experts disagreed with them.

Whatever the truck was carrying and whatever caused the explosion, I’m just grateful there was no bicyclist riding through the danger zone. See the implosion for yourself in the video embedded below:
