Late Sunday units responded for a crash on I-70 in Cooksville. At 22:30 the station was alerted for the reported vehicle overturned on I-70 near Route 97. Units arrived at Westbound I-70 just west of Route 97 to find a pickup truck on its roof on the slow shoulder with a single occupant who had self-extricated. The pickup struck a truck-mounted crash attenuator that was on scene protecting work crews painting new stripes on the roadway. A crash attenuator is a device that is attached to the back of a truck positioned behind the work area and is designed to absorb impact in the event of a rear-end collision. The single occupant was evaluated by Paramedic 135 and transported priority 3. Units cleared at 23:10.
