First off, I don't take these kind of cases. Second, we don't know all the facts. We haven't seen the police reports, the interviews with bartenders, the truck driver, etc. So, lets hold off before condemning someone as the scum of the earth. Most states do have what is called a dram shop law. Basically, a tavern owner cannot serve an intoxicated person. If they do, they are considered PARTIALLY negligent. Do you think a tavern owner is going to voluntarily admit that they overserved a guy? Nope, thus the lawsuit. As for the other parties if there is no reason for them to be in the suit, they will be dismissed. If the lawyer who brought the case didn't have any reason to do so, he/she can be punished (yes it does happen cynics). Do I like this suit? No. But if Dad has been asking questions and not getting any straight answers, it is within his right to bring suit. If people always told the truth or always did what they contract to do, there would be no need for the legal system. EDIT: Hawing, to respond to your question, some form of negligence on behalf of the stalled driver is possible. If that stretch of road lacks a left hand shoulder, and they had the opportunity to get over before stopping, they may have created a dangerous situation. No, they would not be 100% liable, but some percentage could be attributed to them
