Utah Highway Patrol Lt. Cameron Roden said a southbound Toyota Tacoma was waiting to make a left turn, when the driver of an electric vehicle approached the truck from behind and realized they didn't have enough room or time to stop.
To avoid a collision, the driver of the Chevrolet Spark swerved into the northbound traffic lane, where they collided head-on with a Chevy Silverado pickup.
The driver of the Spark was airlifted to a local hospital to be treated for serious i juries, Roden said. Others involved in the crash suffered only minor injuries.
The accident appears to have happened just before 5:30 p.m., based on a post from the Wasatch County Sheriff's Office announcing the closure of SR 113.
Roden said the highway is expected to reopen this evening.
