Authorities say a 16-year-old girl led police on a high-speed chase through Laurel that ended when she crashed and was partially ejected from the vehicle.
Laurel Police Officer Fred Gregory tells The Billings Gazette officers received a call early Thursday that a 15-year-old girl with the driver had been run over at a gas station.
The caller said the vehicle also rammed several gas pumps.
Officers pursued the driver south on Highway 212 at speeds of about 85 miles per hour before she lost control near Beartooth Way.
Gregory says the vehicle went off the road and rolled several times. The driver was not wearing a seatbelt and was airlifted to a Billings hospital.
The 15-year-old girl also was taken to the hospital.
Their conditions were not immediately known.
