A 13-year-old Eagle Mountain boy was critically injured when he apparently rode a motorized scooter through a stop sign and was hit by a car on Wednesday afternoon, according to police.

Sgt. Spencer Cannon of the Utah County Sheriff’s Office said the collision occurred shortly before 4 p.m. The boy was traveling west on Horizon Drive when he went through a stop sign and collided with the front driver’s side of a car that was southbound on Hummer Drive. There is no stop sign on Hummer Drive at the intersection.

The 13-year-old was thrown 70-80 feet, according to Cannon. He was taken by ambulance to Timpanogos Hospital in Orem in critical condition, and later flown by helicopter to Primary Children’s Hospital in Salt Lake City.

According to Cannon, the 19-year-old woman who was driving the car was not speeding, and neither alcohol or drugs appeared to be factors in the collision.
