Power Steering Pump problems of the 2012 Toyota RAV4

I was driving westbound on I-70 around mp 129. This is just before glenwood canyon. There was a flashing icy road sign at which time, I signaled my intention to move to the right lane which I did. I slowed down and put my car in 3rd. This was just before a curve to the right where the road and visibility narrow. The right lane was completely iced over as I realized when I got around the curve. In front of me, I saw a pileup, both lanes of traffic were blocked. I tapped my brakes to slow down but because of the ice, I did not stop or slow down. I went around one car stopped in my lane to avoid hitting it from behind. I went around on the shoulder. I continued to pump the brake. Immediately in front of me was a sierra 4x 4 that was perpendicular to the lane of traffic and it was also blocking the shoulder. I plowed into it about the middle of the truck at a rate of anywhere of 25 - 30 mph. My airbags did not deploy. My dog and I were both restrained and we suffered no injuries. My car is in all likelihood totaled.
