A commercial trucker hauling a load of cased wine collided with two smaller vehicles Monday morning after coming upon stopped traffic on Highway 101 in downtown Santa Rosa, the CHP said.

John Schrack, of Modesto, was northbound near Highway 12 when he reportedly veered to avoid hitting stopped vehicles ahead, clipped one, causing his truck to lose a wheel, and then rear-ended another, the CHP said.

The 7:56 a.m. crash sent the two other drivers, Alejandra Lopez, of Santa Rosa, and Elena Meuse, of Rohnert Park, to Santa Rosa Memorial Hospital for evaluation of pain, the CHP said. But there did not appear to be any severe injuries.

Schrack's disabled rig was stuck in the roadway for an hour, however, blocking the middle and slow lane, as well as the downtown Santa Rosa exit, the CHP said.

The roadway was completely reopened at 8:56 a.m., the CHP said.
