HARRIS COUNTY, Texas – Isaac Hernandez didn't think twice when he saw a car crash into an 18-wheeler and flip, leaving its driver hanging out of a window.
"It was 4 in the morning, me and my wife were coming home from a fishing trip," Hernandez said, recounting a drive home Sunday morning at Beltway 8 and Woodforest Boulevard, where he saw the collision. "I see the car flipped over and I don't see anyone around so I told my wife, 'Hey, pull over. Pull over. Pull over,'" Hernandez recounted.

Video recorded from Hernandez's cellphone captured what he did in the minutes which followed. Hernandez told KPRC2 he did not intend to record the accident scene. Rather, he needed the light from his phone to see. What he saw left him shocked, leaving him no other choice, he said, than to help.
"Once I see that the body is still in there. The head was hanging out on the curb," Hernandez said.
According to Hernandez, the driver he rushed to help had crashed into the back of a delivery truck near the parking lot of a Kroger at Beltway 8 and Woodforest Boulevard. The driver of the truck can be heard in the video, as well, assisting Hernandez, who sprang into action.
"Are they all right?" Hernandez can be heard in the video asking the truck driver.
"I don't think so," the truck driver can be heard replying.
"We gotta get in there, man, call police," Hernandez followed.
The video then shows Hernandez rushing to the car. Its driver can be seen hanging out of the window. At this point, according to Hernandez, both he and the truck driver smelled smoke. They figured they would try to pull the man out before fire engulfed the car.
"I was like hey, man, there's something burning. There's a guy right here. This car can go into flames any minute," Hernandez said.
Fortunately, the car did not catch fire. Hernandez pulled the man out of the car. Harris County sheriff's deputies arrived on scene, as did paramedics, who rushed the man to the hospital.
He lived.
"I just thank the good Lord that he blessed me. Put me in the situation to be able to help this young guy," Hernandez said.
Hernandez's efforts come as no surprise to wife, Kimberly, who pulled over and watched her husband potentially save a life.
"He's always trying to help people. Any way he can, he will," said Kimberly Salinas.
The Harris County Sheriff's Office is investigating the crash, including what caused the man to strike the back of the delivery truck.
