I came back to my car and found out it was being towed. I asked the tow truck driver why and he said that it was illegally parked. I told him it was not and we got into an argument. He then hit me, breaking my jaw. Can I sue the tow truck company for this injury?
Perhaps. The tow truck company is not responsible for the intentional acts of a tow truck driver, and from the description of the incident it sounds like this was an intentional rather than a negligent injury.
However, an employer can be held to bear some level of responsibility when its employees intentionally cause harm if the employer negligently hired, trained or supervised the employees or negligently failed to fire them if the employer knew or reasonably should have known that the employee presented a risk of injury to members of the public.
