Twisting of Safety Chains has also been shown to cause a trailer to roll when the forces of torque are applied in a disconnect situation. Properly lengthened chains not twisted accept the load without additional torque issues.

Dragging chains too long have been shown to start fires. Much safer to twist them, if needed, ensure you are hooked up properly and head down the road.

At work we had a fleet of different trailers & a bigger fleet of all different kinds of trucks to pull them so the only way to shorten or lengthen chains to accommodate everyone was to twist or untwist to fit, in 30+ years employed there we did have a few come loose & the chains did their job as designed even being twisted.
One thing I noticed in the video was that it appeared to be galvanized chain which is not the correct chain to be used as safety chains as per DOT, at least not on commercially licensed trailers. There's also DOT requirements on the hooks that's approved for safety chains & locations to attach the break away cable.
I've also never seen nor heard of the twisted chain causing the trailer to flip due the chain torque. As I said I've experienced a trailer come loose, with the chain twisted, the tongue cradled in the chain never hitting the ground & followed straight behind, it did ding up the tailgate & broke a taillight, incident had a very high pucker factor. If the tongue hits the ground then it's anybodys guess where or what it'll do.

Might we see some data or a source or two covering this information?

Twisting them puts a side load on them, they are designed for a straight pull. Someone said it's easier to twist them then to start a fire, I disagree. It's easier to make them the proper length.

There is a difference between twisting and wadding them up in a knot. It's becoming more scarce but a little common sense goes a long ways. Been twisting chains for over 40 years, no other way when using different vehicles.

A lightly twisted chain certainly is preferred over a chain wadded into a twisted ball. (The twisted ball is what one would get when using the uhaul length chains as was identified in a prior post.). The lightly twisted chain would still be subjected to torsional forces whereas a chain’s primary loading is to be in tension. Better to take the slack out of the chain using zip ties or a bungee cord that will break away.

Okay, don't get riled up: If you twist one chain clockwise and the other counterclockwise does the twisting effect offset?

I like your humor.
It will counter the twisted flip that was predicted.

Or would that make the trailer roll end over end rather than "twist" or "corkscrew" down the highway?????

I suspect the chain was rated for far more than the weight of the trailer, so this was not a risk. I notice the cahins on my Load Trail 10K payload dump trailer are barely long enough to hook on there, which tells me a twist is not recommended...

I also noticed no data showed up and no videos either showing trailers rolling over because of the twist in the chains.

Just an observation: You can sure tell that nobody is having any "RV related problems to solve" when we have 4 pages of discussion about what happens if you twist the safety chains.....
I'm definitely not complaining, in fact, sort of happy that "things RV related" are going so well......
