If you are asking whether the delay in obtaining a diploma is compensable in Wisconsin then the answer is yes. I agree with the other attorneys that you should talk to a personal injury attorney and use the find a lawyer option at this website. Good luck.
If the other driver was a semi then there is a great likelihood that he has insurance. You can look online or hire an attorney to help find their insurance and make a claim ASAP. That is probably your best bet to get your truck fixed.
I agree that you should call the attorney and see if a time after work or on a day off is possible. But please know that there are deadlines that must be met or the court may sanction either side. If you delay or ignore, the attorney may have no choice but to force you with a Subpoena to testify at a deposition. If you ignore a Subpoena the court can issue a bench warrant and ask for you to be picked up and brought before the court.
