Steven J. Kissick, 39, was injured in the single-vehicle crash, which occurred just after 7 a.m., according to California Highway Patrol Officer Steve Tanguay.
Kissick was driving his 2003 Toyota Tacoma truck northbound on Hill Road south of Helbush Drive at an unknown speed when his pickup drifted off of the roadway to the right as he was traveling through a lefthand curve, Tanguay said.
Tanguay said Kissick turned the steering wheel back to the left and lost control of the truck, which then crossed the roadway to the left and began to roll over.
While the pickup truck was rolling over, Kissick was ejected from the truck, Tanguay said. The pickup came to rest on its wheels west of the roadway.
The Lakeport Fire Protection District responded and Kissick was flown by REACH helicopter to UC Davis for major injuries, said Tanguay.
Tanguay said alcohol and drugs are not suspected to be a factor in this collision.
CHP Officer Joseph Wind is investigating the crash, Tanguay said.
