WINDSOR - A San Jose man lost his arm in a solo vehicle crash on southbound U.S. Highway 101 in Windsor Saturday night, according to the California Highway Patrol.

The crash occurred around 10 p.m., when a 2006 Toyota Solara driving south on Highway 101 just south of Shiloh Road came upon a tarp in the road, CHP Officer Marcus Hawkins said.

The driver, 27-year-old San Jose resident Zhang Huijing, swerved to avoid the tarp, ran off the road and struck a tree, Hawkins said.

The passenger, Andrew Chang, 29, was injured when the passenger side struck a tree. His arm was severed from his body, Hawkins said.

The driver suffered only minor injuries.

Alcohol is not thought to be a factor in the collision, Hawkins said.
