Those trailers are really low. Guaranteed he got high centered and as soon as that happens all the weight comes off the drive tires because the air suspension dumps. The tires now have just slightly more traction than if they were hanging in mid air.
he was definitely badly high-centered. I had to look up the story and thank goodness no one was seriously injured.
And to those making fun of the driver wailing and waving his arms--in hindsight it was kind of funny, but at the time the guy may have thought he just killed a train load of people. Or at a minimum lost his job or his livelihood with that rig.
In a real crisis most people don't know what to do so they act irrationally or (more often) don't act at all. Rare is the individual who can keep a cool head and act quickly in the heat of the moment. And it is is usually NOT the guy you would expect.
