BRYAN, Texas (KBTX) - Zach Seaback doesn't remember much about the moment his vehicle rolled over on Highway 6.

Doctors told the 23-year-old father of two from Grimes County that he suffered a severe concussion, and his head was literally split open at the top, but Seaback vividly remembers what happened after the crash: strangers running to help and staying with him until medics arrived."I don't remember much. I had an insane concussion," Seaback said.

"I looked up and saw an 18-wheeler, and I tried to swerve around it. And I clipped his tire. I think I'm not really 100% positive what happened. And then I rolled."The crash happened on Wednesday on Highway 6 in Brazos County, south of College Station, near FM 2154. He said he was scared as he tried to get out of the wreck, not knowing whether he was still in the roadway."I didn't know if I was on the highway or not," Seaback said.
