We had a car accident on I-84 in Oregon, westbound, was hit on the driver side rear area which caused us to spin around. We were hit by a semi truck on the driver side rear. We ended up perpendicular to the concrete median (this is a highway with two lanes on either side) which is what stopped us. The semi truck also sustained damage to their passenger side front wheel and had to be towed. Our car had to be towed. None of the airbags went off. The back window of the RAV4 hybrid was gone. There was damage to the front passenger side, front, rear driver side, rear of car. Sheriff and Oregon state patrol came, both vehicles towed. Contacted Toyota who says they are going to retrieve event data recorder box to investigate. We have a police crash report case #.
