We are being sued by a car salesman after taking a test drive in a car and apparently injuring the salesman. We did a u-turn after coming to a complete stop, the salesman was in the back seat with no seat belt on, and ended up on the floor. We asked if they were ok, and they answered yes. 3 years later, they are claiming they were severly injured in the event and are completely disabled. Will our car insurance cover this?
