    Utility brand dry box trailers are noted for being one of the lightest constructed box trailer on the road. Without seeing an accident report I can tell you that the load inside had at least 1 heavy pallet stacked on top of another and if it had been secured at all often box drivers do not even look inside of their trailers when they are ;loaded, the load locks when used only extend from side to side and there sometimes are no vertical E tracks for strapping to.
    The impact of a 2500 lb pallet falling from 3 feet high un a turn could have been enough to cause the trailer to collapse especially if the trailer was loaded heavy in the first place.
    Remember these trailers have no frame only a short sub frame where the axles are All of the structural strength in them is from the thin siding and the even thinner roof the only other structure in these trailers is the extruded runner that joins the roof and the side walls

    "All things being equal" (lol), this video just gave me, yet another, reason to avoid riding alongside any tractor trailer. But now, I'm going to spend the rest of my driving days on special lookout for that brand of trailer!

    It is not limited to only one brand many manufactures make almost the exact same design of trailer I own a Great Dane branded name and it is made the same way also has damage on the top of 1 side where the skin of the roof and the skin of the side wall have ripped the rivets out of the top rail Not collapsed but only suitable for limited storage as well

    Load restraints can only prevent so much movement. Eventually inertia will overcome even the best secured load in extraordinary circumstances

    Especially with that electric pallet jack up high in the load at :06...lot of heavy stuff there. More to me was the nonchalantness of the guys standing there when it came toward them at :08! No worries...it's all good.

    Truck has already tipped onto it's right side which would have tossed everthing about and then when winched back upright contents came tumbling out.

    Yeah I doubt if they were expecting to encounter such a displaced load or they would have had another line to arrest the sudden movement in righting the truck.
    Most reputable towing companies would have used arresting lines even on an empty truck to prevent further damage to the vehicle or the possibility of a kinetic energy tip over the other way.
