Regardless of the merits of their lawsuit against you, I don't think they can withhold you last week's pay for any reason. I'd check with your loca labor board. There are federal regulations regarding pay and what can and cannot be done with it. They'll help you for free if it's deemed that your employer withheld money illegally. Of course, whether you were an "employee" versus an "independent contractor" or something may have bearing, but I do not know. The lawsuit is a separate issue and I suggest you get an attorney. Don't trucking companies insure their rigs or is it your responsibility to insure it? What's the insurance's take on the matter? If you got in an accident, whether it was your fault or not, the insurance should cover it. This also could be construed as "work-related" if there were any injuries involved. there may be recourse there also. Talk to the labor board re; pay owed. Then an employment attorney re: the lawsuit.
