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. *TR
