Seriously, in these kinds of accidents that are chain reaction, the guy that caused is seldom any where around. Some clown panics hits his brakes, the result of which is not realized till much further behind him.The reason a semi is usually involved is because most drivers view them as nothing more than a nuisance and don't give them the respect they deserve. Until we stop giving everyone that has the ability to breath a drivers license we will see this more and more.
