department of public safety catches a pickup truck speeding. it takes a bit longer than usual for the driver to pull over. >> he didn't want to stop for me. you can hear me in the video i say he didn't want to stop for me. it's just something i took note of but it was nothing that would cause me to be on alert immediately. >> his dashboard camera begins recording a bone-chilling incident that the highway patrolman still can't believe he survived. >> and i thought, man, you ain't going to make it through this. it was very scary. >> it begins as a routine traffic stop. >> how you doing, sir? >> all right, sir. did i do something wrong? >> you were a little bit over on your speed. >> i was just behind that truck. >> well, you were going faster than that truck. you were gaining on him. just need to see your driver's license and insurance. >> trooper stone can sense that something isn't right. >> he was very nervous when i was talking to him in the vehicle. go ahead and step out of the truck for me. he stops at the door. and he's doing something with his hands.
