Emergency responders treat victims and interview witnesses after Wednesday's crash.
Four area teenagers were hurt - one of them critically - when the pickup truck they were riding in rolled on a dirt road south of the Fairgrounds motocross track Wednesday afternoon.
Carbon County Sheriff's Lt. Tory Christiansen said the truck apparently rolled over a 16-year-old male passenger who had been ejected as it spun. The boy was transported by helicopter to Utah Valley Hospital with suspected broken ribs, punctured lung and pelvic injuries.
The driver, who was also a 16-year-old boy, and two girls were slightly hurt in the wreck. Christiansen said alcohol was a factor and the driver was cited for DUI.
The lieutenant said the vehicle, a 1998 Chevrolet pickup, was southbound on the gas well road at about 1:30 p.m. when it entered a curve going too fast. The back end of the truck spun into a roadside ditch, causing the truck to flip in a full rollover, coming to rest in an upright position.
A motorcycle rider who was apparently with the group drove to the nearby Events Center, where he found a deputy who was taking a dog training course at the time and was able to radio public safety dispatch to summon help.
