Well, it depends on what the policy says and what the law says. It seems surprising to me, though, that if someone intentionally runs into you in an effort to commit suicide, then you don't have a claim against their insurance company, but if it's an accident, then you do.
Maybe that's the way it is, but I would not assume that is the case simply because a jury said so. Afterall, it's a legal issue, not a factual issue, and it's the judge who decides legal issues, not the jury. The judge let the case go to the jury, so he apparently thought that the legal issue was in the trucker's favor.
The other possibility is that the judge agreed that the policy did not cover suicide, but he wanted the jury to decide whether the other driver was actually trying to commit suicide, or whether it was simply an accident. I suspect that the guy did not leave a suicide note.
Now, since the guy did not leave a suicide note, who decided that he was indeed trying to commit suicide, thus nixing the trucker's chance of just compensation for his medical bills etc.(...which me thinks were picked up by either worker's comp and/or disability insurance anyways)!
Me thinks Progressive is just washing this guy out on technicalities. Keep in mind this company next time you're looking for car insurance!
