OREM — A Utah Valley University student died Tuesday after she was injured in an accident on I-15, the Utah Highway Patrol reported.

Amanda Clifford, 20, of Lindon, was taken off life support around 2:15 p.m. at Utah Valley Regional Medical Center following an accident Tuesday, UHP spokesman Cameron Roden said.

Clifford was in a car headed south at about 8 a.m. Tuesday on I-15 in the far right lane, Roden said. Witnesses said it looked like she was cut off just north of the 800 North exit in Orem, Roden said.

Clifford's car went out of control and ended up swerving into the lane to her left. A semitrailer then hit the driver's side of the Honda Civic, Roden said.

The semi and the Honda ended up toward the right, but still in the middle of the road, Roden said.

The freeway was closed for 10 to 15 minutes while a medical helicopter landed and took Clifford to Utah Valley Regional Medical Center in critical condition. The truck driver was not injured, nor was he cited, Roden said.

Officers believe Clifford was traveling to UVU, where she had a 9 a.m. class.

Family members weighed whether to keep Clifford on life support, Roden said. She was taken off life support around 2:15 p.m.

Roden said investigators still have no information about the vehicle they believe may have cut Clifford off. He said anyone with information regarding the incident can call 801-374-7030.
