answer:Well, I’m not a lawyer or a cop, but I learned that you are responsible for everything in front of you. Thus, I would think that the person who hits the person in front of him his responsible for his part of the accident. I.e, the kid is responsible for 25% of the damages to the semi, and 25% responsible for the damages to his car. The first school bus driver is responsible for 25% of the damages to the semi, 25% of the kid’s car, and 50% responsible for the damages to his bus. The second school bus driver is responsible for 12.5% of the damages to the semi, 12.5% of the damages to the kid’s car, 25% of first school bus, and 100% responsible for the damages to his bus. Of course, since the kid was texting, maybe that should shift a little of everyone’s percentages to him. But again, this is all just my opinion. I have no clue what the law says about this. I’m guessing the lawyers are gonna have lots of fun over this :-p
