This case involves a mid-sized sedan. The plaintiff, a forty-five-year-old man, was traveling south on a major highway when he was struck from the front by the wheel and tire assembly that had detached from a truck that was on the other side of the highway. The tire rolled across the hood of the plaintiff’s car and crossed the header over the windshield and above the plaintiff’s head. The upper header of the plaintiff’s car slid out of its unattached position at the side rails along with the roofing skin into the passenger safety compartment of the car. This caused the roof structure of the car to hit the top of the plaintiff’s head, resulting in multiple fractures and leaving him paralyzed. The plaintiff later regained the ability to walk but was left permanently disabled due to central cord syndrome, which is an acute type of spinal cord injury. The plaintiff also suffered a mild traumatic brain injury and remains unable to work or participate in many activities of daily life as the result of the accident.
