A truck driver in the United States uploaded footage that was recorded by his dsahcam of a Ford Excursion towing a caravan, which began to sway, got out of control and ultimately flipped itself and the large SUV that was hauling it.
The trucker was driving down the Interstate 82 in Washington when the Ford Excursion pulling the caravan passed him at about 105kph. Everything looked fine until a few seconds after the Excursion had passed, when the trailer began to sway. The swaying continued to get worse and the speed indicator on the video suggests the Excursion didn’t attempt to slow down.
The swaying eventually gets bad enough that the caravan’s passenger side wheels leave the ground. When the wheels come crashing back down seconds later as the Excursion leaves the roadway and then all you see is clouds of dust as the two flip.
The truck driver brought his truck to a stop and offered his assistance. Fortunately, he reported that everyone was okay but they were likely very shaken up about the crash.
