Three people from Rock Springs, Wyoming were injured during a collision between a car and a semi tractor-trailer Wednesday evening, in Adair County. The Iowa State Patrol reports the crash happened at around 7:52-p.m. on Interstate 80 eastbound, near mile marker 75.

Authorities say a 2013 Toyota Camry driven by 68-year-old Pamela Willey, of Rock Springs, rear-ended a 1999 Peterbilt semi, which was disabled on the roadway due to an accident that had occurred a few minutes earlier. The car came to rest partially under the trailer of the semi. Pamela Willey, and her passengers, 85-year-old Harold Willey, and 68-year-old Faye Frolic, were injured. All three were transported to Iowa Methodist Hospital in Des Moines.

Pamela Willey and Faye Frolic were flown by Lifeflight to the hospital. Harold Willey was taken there by Adair Rescue. None of the crash victims were wearing seat belts. The driver of the semi, 64-year-old Robert Johnson, of Crescent, was not hurt. Assisting the patrol at the scene, were Deputies from the Adair and Cass County Sheriff’s Departments, Adair Police, numerous local rescue units, and Life Flight.
