OREM, Utah (AP) - A state trooper changing a tire for a woman stranded on Interstate 15 put her in a bear hug and dived over a concrete barrier Thursday, moments before a sport utility vehicle smashed into his patrol truck, police said.

"Had the trooper not acted as he did, both he and the woman would most certainly have been crushed to death," said Lt. Doug Edwards of the Orem Department of Public Safety.

Trooper Bryce Ivie of the Utah Highway Patrol arrested the 28-year-old Provo man and turned him over to Orem police. The driver was in custody on suspicion of drunken driving.

After it was hit by the SUV, Ivie's truck crashed into the woman's car and all three vehicles moved 50 feet along the barricade, Edwards said.

"With all three vehicles coming straight for us, I grabbed the lady and threw both of us over the cement barricade," Ivie said.

Jihae Song, 25, suffered minor injuries, mostly scrapes from going over the barricade, he said.

Ivie, 29, had heard reports of a reckless driver just before the crash. While changing the tire, he looked up and tried to get the license plate of another suspicious SUV moving north on the freeway.

"He was then prompted to look back to the south and saw the suspect's SUV barreling down the shoulder of the road and headed straight on," Edwards said.

At that point, everything "kind of went into slow motion," Ivie said. The SUV hit the trooper's parked truck which then hit the passenger car where Ivie had been changing the tire.

After the dive over the barricade with Song, Ivie, who is 29 and has been a trooper for seven years, returned to the SUV. The driver had his foot on the accelerator as the trooper banged on the window and told him to put the vehicle in park. Ivie opened the truck door and did it himself, taking the keys.

The driver looked "completely out of it," Ivie said. He told the trooper he was having a panic attack.

While troopers aren't necessarily trained for these specific circumstances, they are trained to be aware of their surroundings and imagine how they would react in a variety of scenarios, Ivie said.

"I'm just lucky I was in a position to be there to help," Ivie said.
