A 24-year-old Idaho Falls woman succumbed to her injuries Saturday night after she rolled her vehicle on Interstate 15 2 miles south of Dillon.

According to a narrative released from the Montana Highway Patrol, the woman was driving north around 5:30 p.m. when she lost control of her vehicle and drove off the roadway to the left. She overcorrected, reentered the roadway, drove off the interstate to the right, and rolled her vehicle twice, the narrative said.

The 24-year-old sustained head, neck, and chest trauma and was transported to Barrett Hospital and HealthCare in Dillon. The narrative did not say when she passed away.

Montana Highway Patrol suspects drugs and speed may have been involved in the accident, the narrative said. The woman was wearing her seat belt at the time of the accident.

This is the 173rd road fatality to occur in Montana this year.
