I don't know about anyone else in how they respond

I don't know about anyone else in how they respond and of course I have a few stories but seeing that other trucker next to him I would have thought he would had laid on his air horn which would have alerted the trucker before hitting the truck ahead of him, Now let me also be clear that you never pull a hard left or right with those trucks but I still believe he had time to at least lock up his brakes and I just don't see that. It is also hard to see/judge if he slowed at all but if not he may have fallen sleep at the wheel or a truck with poor braking system to begin with. It sure looked like when that red truck swung around that it had to of hit that car but I guess not.

btw....was those 5 white things bags of groceries flying in the air or perhaps several bags of something from Home Depot?
