TOOELE, Utah -- Two people died in a three-car crash on I-80 near Tooele early Monday.
It happened at approximately 1 a.m. when police said a driver went off the road and over-corrected while headed east on I-80 near mile post 99.
The driver, a man believed to be in his 30s, swerved back onto the road, but lost control of the car. Officers said the car flipped onto the highway and rolled several times.
Police said the woman in the passenger seat was thrown from the car and was hit by a semitrailer.
The driver, who remained inside the car, also died in the crash.
"Looking at it at the scene, it did look like they were restrained, just not sure if the passenger was restrained properly," said Sgt. Donavan Lucas, Utah Highway Patrol. "People put their seat belt on and put it behind their back, or something like, and that is not the proper way to wear a seat belt."
After the car rolled, a second car crashed into it from behind. Police said no one in the second car was seriously hurt.
Police have not released the names of the victims, but officials believe they were related. Their car had Texas license plates.
Officers continue to investigate what led to the crash, however they said drowsy driving may have been a contributing factor.
