I made a statement and signed an accident report for the trucking company. Does that mean I do not have a case?

Although I would recommend that you not make a statement or sign an accident report for a trucking company without first having seen or spoken with an attorney, it does not mean you do not have a case. How those documents will impact your case depends upon what was said. I recommend that as soon as possible, you seek counsel from an attorney who’s qualified in this area.
