Of all the accidents I have seen, only 1 in 10 does the operator admit to it being his fault. I can't see how he was thrown from the truck. If the tail "swung", the articulation plate stops were not adjusted right, or the operator was going too fast, the floor was uneven, or he tried to jump out. This is all just my opinion. I agree with the above message:"STAY IN THE TRUCK". I have driven fast Raymonds and Crowns where the brake would lock up or the truck slid in a turn because of slick of un even floors. I no circumstances did I ever expericnce a force that came close to throwing me from the truck
