JOHNSTON COUNTY, OK -- Troopers say it was at the intersection of Highway 78 and Highway 22, that 16-year old Collin Sullivan's truck was broadsided by another car.
"The young man that was driving the pickup had some dew on his driver's side window, " said OHP Trooper Rodney Davis. "From what I understand, and he had cracked his window to be able to see whether or not it was clear to proceed from the stop sign and turn left, and from what I understand, he didn't see the other car."
In that other car were 72-year-old Wanda Beal, and 18-year-old Desteny Albertson.
Trooper Davis says all three people involved in the crash had to be flown to hospitals. Sullivan was taken Parkland Hospital in Dallas, and Beal and Albertson -- to OU Medical Center.
Johnston County EMS director, Kenny Power, says Albertson suffered the most serious injuries
"One of them was in the back seat and thrown into the front seat was broke," said Power. "She had multiple lacerations and real serious right leg wound that was going to require immediate surgery. She was our priority one to get out first."
Davis says Sullivan has already been released from Parkland hospital, but Albertson and Beal both remain at OU Medical Center.
He says no one was wearing a seatbelt.
"Anytime we see a major crash or a head on crash seat belt usage is critical in slowing down a person's body so it reduces the amount of trauma that they sustain in the collision," said Davis.
Davis says failing to stop or yield at a stop sign is one of the top 5 causes of crashes, and reminds all drivers to use caution.
OHP says Sullivan will be ticketed for making an unsafe turn.
