Trailer sway crash - GIF

Is there anything to be done, once the swaying first starts, to avoid the roll over?

I always heard that locking up the trailer brakes will help, but haven't seen that method tested.

Step on the throttle. The driver saw a short opportunity to get around the slower vehicle, and mashed the throttle to the floor. Once he got clear, he backed off. Now the trailer is going faster than the truck, trying to push it down the road.{never works} Simple solution: step on the throttle {gently} until the truck is once again pulling the trailer down the road. Works with almost any combo of tractor/ trailer, on almost any surface.
Watched this happen probably a couple dozen times in 12 short years in the trucking business.
The other thing to do is don't panic. Just walk into the throttle and drive on.
