The driver of the UHaul can be sued.
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
First of all, report it to your insurance company. Your insurance company likely will take appropriate action. However, both UHaul and the driver of the UHaul truck can be sued.

Report this to your insurance company. You may have underinsured coverage. If not, then you may be able to sue the U Haul driver. Good luck.
