At least three people were injured in a small plane crash that took place near Interstate15 in Weber County, Utah, on Sunday afternoon.

Officials said the plane crashed after it hit a billboard near the side of the freeway, about half mile southwest of the Ogden-Hinckley Airport. Two occupants and a bystander were injured in the incident. While one of them was airlifted to the hospital, the other two were transported by an ambulance.

Confirming the same, police officer Stuart Hackworth said the bystander suffered smoke inhalation after he stopped to help.

"We do initially appreciate assistance from the public. And then once we arrive on scene, we greatly appreciate their cooperation in letting us and emergency medical personnel do our jobs,” Hackworth said. According to reports, two of the three injured were in critical condition.

Meanwhile, Southbound I-15 was shut down in the area where the crash took place. The Utah Highway Patrol asked commuters traveling I-15 north to not slow down or stop to observe the crash. The crash will be investigated by the Federal Aviation Administration and National Transportation Security Administration.
