Let's hope the driver was wearing his seatbelt. I had a driver once, no seat belt, and involved in an accident and thrown from the vechicle. And his package car was still rolling down a 4 lane road until it crashed into a guardrail.
Could have been a lot worse with someone else getting hurt or he could have gotten run over by his own package car.
Went to see him in the hospital and he asked that I let all the other drivers know to wear their seatbelts at all times. That was the PCM the next day.
He never did come back to work and was a great driver. Permanent disability at age 48
