On a curve... at Deer Creek Reservoir... a semi-truck carrying propane jackknifed and lost control... hit the guardrail and crashed into the reservoir. This happened overnight, and when UHP arrived they had to make a tough decision on how to conduct the search for the driver and how to remove the semitruck from the reservoir. Heather Kelly from the KSL Traffic Center explains how this will impact the surrounding areas. Utah Highway Patrol's Lt. Cameron Roden provides updates on the tanker truck in the reservoir and the search for the driver.
