I was in a car accident involving an eighteen-wheel truck. The driver thinks the truck hit the car. I was in the passenger seat and I think the car hit the truck. Can someone give their opinion given the details: The car was traveling in the left lane at about 70 miles on the highway. The truck was next to the car in the right lane. Suddenly, the car started veering slightly out of its lane to the left. I was very suprised and looked over at the driver to ask what was happening. There was no sound or push or vibration at all. Then the car swung to the right perpendicular to the truck's middle part. The truck was directly in front of us and I think part of the car's hood went under the truck. At this point, the car began spinning and flipped about three times before landing in the median facing the opposite direction. Miraclously, there were no major injuries but the car was totalled. The reason I believe the truck did not hit us is because there was no sound or vibration at all before the car swung to the left. It was a huge truck and I've been rear-ended, so I know if you get hit, you will hear the noise and you will feel the impact when you are hit even by a small car at a low speed. The police report states that the car veered out of the lane and overcorrected itself, but the driver insists the truck hit us. Can anyone offer their opinion by applying some physics knowledge? Thanks.
