A semi truck rolled over Wednesday afternoon on West First Street in Craig. The driver, 26-year-old Kalen Study of Casper, failed to navigate a turn when he lost control, sending his tractor-trailer into the ditch. Study was transported to the hospital for treatment. Excessive speed is believed to have contributed to the crash. Photos from the scene of the accident courtesy of Doug Slaight for Craig Fire and Rescue, click to enlarge.
