On Tuesday am I was headed out to West Virginia for a normal day driving my then empty big truck car carrier, on a country country road I came up over a crowned slight rise and rounded a curve, a school bus was stopped on the other side some 300' from where I was, I hit the air brakes and in an instant it took off, jack knifed with an explosive bang coming to a quick stop. Didn't hit anything, stayed on the roadway, managed to back it out of the jacked position and limped it back home.
The floor is heaved torn from the frame mounts, air ride seat twisted around a bit too. Heavy damage to the left side to the tractor, stoved in and twisted the cab pretty good above the fuel tanks and also crushed the side and twisted the open deck trailer. Seat belts work boys and girls ...... kept me tightly in place and was able to walk away with a scratch.
