A one-car rollover sent a Milton-Freewater man to the hospital early Saturday morning, the Washington State Patrol reported.
Juan M. Cisneros-Diaz, 41, was driving a 2004 Peterbilt tractor on Highway 125 at about 5 a.m. when his 2004 Peterbilt tractor failed to negotiate a curve in the road, slid off the highway, rolled, then came to rest on its top.
The accident occurred near Valley Grove, about six miles north of Walla Walla. No drugs or alcohol were involved with the crash, the WSP stated.
Cisneros-Diaz was transported to St. Mary's Hospital in Walla Walla.
The WSP said speeding charges are pending.
