Well, scary accident. Im quite aware of the risks in the trucking business, there are many powerful things which can be potentially dangerous if not keept in good condition, which is why its important to make sure everythings in check, but humans are lazy, so i understand. Im a becoming truck driver aswell (atleast here in Sweden were we have "gymnasium" after 9th grade, i guess its the high school equivalant or whatever, and theres a choice for a "Vehicle Program" where there are different directions, and im on the second year of the Transporting direction) and atleast our teachers tell us about the risks, and when you see all the different parts you will quickly understand how things can become a danger if something goes wrong!
