A 19-year-old man was traveling west on I-20 when he ran into the back of a work convoy near Mile Marker 292 in east Taylor County.
Police say the man was reaching for his cell phone in order to make a call when the accident happened.
The convoy driver says he saw the truck coming and attempted to pull forward, but could not move fast enough. The truck driver also looked up in time to see the convoy, but could not come to a stop in time.
The 19-year-old was transported to Hendrick Medical Center with non-life threatening injuries.
