Oh dear. Thats about as stupid an advertisement as its possible to make.

These are quite scary:

Note, some of the shots are the same crash at different camera locations.

Can someone please tell me what happened with the two trucks? I just can't figure that one out.

I'm more than willing to have a go at motorists attitudes towards cyclists but this is just insane. How can anyone be expected to deal with some idiot turning in front of them without even signalling never mind looking? (and yes I realise that in the precise situation shown he could have taken evasive action or even stopped if he had been paying attention)

Does one truck pull out of a side slot in the tunnel? As the previous crash ends, it looks like a truck is prked in an opening, then at the end of the truck sequence, somebody is waving traffic around the accident already - might have been "seeing" out the driver!!
The second truck exits the impact facing backwards!

and WTF is the road surface made out of? Glass?

Loads of the crashes seem to involve things skidding for no real reason.

Oil on the road?

I think that's some Russian tunnel which is notorious for black ice. All of those accidents were caused by inappropriate speed for the conditions!

I'm surprised that significant amounts of moisture could deposit itself in a tunnel.


That's a bit strong. In some cases that is at best a contributory factor

1) Although quick, the driver was being absolutely insane with the last millisecond lane change, their ensuing panic resulting with the loss of control - the classic pendulum swing. This would have been avoided if numpty had changed lanes far earlier (although I'm not a fan of large differential speeds)

2) Unless all 4 cars were at inappropriate speed, the crasher could not have been so (would not have been able to get past as all 3 lanes were in use).

3) Could well have been (but didn’t seem that fast), that could instead have been a mechanical problem.

4) Lane changer didn’t check behind until too late (although there was significant speed differential), then inadvertently cutoff the escape route of the follower

5) I still can't get my head around that one, the ‘other’ truck seemed to have gone into the collision facing the camera ?

6) Extremely poor lane change by the driver in front, no indication of excessive speed or differential. Seems to have been exacerbated by poor brake balance (too much rear) of the crasher

I can see no reason for the bus tank slapper, wow what a ride that would have been, other the possibility of black ice. This is a tunnel, so water could easily be leaching onto the road surface through the ceiling or the walls. I know that our Melbourne tunnel has regular lane closures for repairs to the tunnel walls causing water leakage.

I don't know why I didn't think of that

I've reviewed the crashes again, I'm convinced black ice isn't the problem due to the black marks left by the crashers (except the bus as we can't see what started that one - but it took a suspiciously long tiime for that to stop) and the rate at which the other cars manage to scrub off speed and come to a quick safe halt (even those following in the same lane).

Yeah, but you're both wrong. It's slippery because it doesn't rain in tunnels and badly maintained cars have been depositing oil and rubber for years.

More like pouring in ---try walking through a tunnel - two things you find in there - spray and rats.




Add the water and instant skid pan

I originally saw that film back in June and it came with the following text:

This 3150 m long tunnel in Russia is the longest in-city tunnel of Europe.
There is a river running over it and water leaks at some points. When the temperature reaches -38 degrees like it did this winter, the road
freezes and the result is the attached video taken during a single day with the tunnel camera.

how much fun would the bus ride be......... ?!

So assuming this information is correct the culprit does appear to be ice.

I don't know the rules regarding lane markings in Russia (if there even are any?) but to me the solid white lines would forbid changing lanes. In several of the clips poor lane-changing procedure was a significant factor.
