We don't hear of many trailer actually coming loose (thankfully!), and especially not a 5th wheel. The good part of this story is that the brakeaway system worked as it's supposed to, and it seems nobody got hurt. Awesome!
But yeah, can you imagine being behind that trailer when the brakes locked up, with no brake-lights giving you any warning!!?? Hopefully, being in a bend, everyone could see around the trailer and knew what was happening.
