Troopers say 35-year-old Angela Whitesell was driving west on State Route 124 just after 5 p.m. when she tried to pass a group of slow-moving vehicles. Whitesell's car then collided with a car being driven by 36-year-old Billi Jo Peterson of Burbank.
Both women were taken to Kadlec Medical Center.
The cause of the accident is still under investigation. WSP says alcohol and drugs did not contribute to the crash.
