Michael Hiller, 41, of Vancouver is being cited for driving with his wheels off of the roadway after a rollover crash that took place yesterday afternoon on I-5 northbound at milepost 55. State Troopers say that the crash happened at 1:18 yesterday afternoon, as Hiller was driving about six miles north of Castle Rock. His Chevy S-10 pickup drifted off of the right side of the freeway, then rolled at least once, coming to rest on its wheels. There’s some speculation that he fell asleep at the wheel. Hiller suffered some cuts, bumps and bruises in the crash, and was taken by LifeFlight to Southwest Washington Medical Center. He has since been released from the hospital. Troopers issued Hiller a citation after his release from the hospital.
