VACAVILLE - Three people suffered minor injuries in a crash involving two big-rigs that has snarled traffic on westbound Interstate Highway 80 in Vacaville this morning, California Highway Patrol officials said.

The crash was first reported at 4:11 a.m. on westbound Highway 80 just west of Lagoon Valley Road. A hazardous materials team has responded to clean up gas and oil that leaked from at least one of the trucks, CHP Officer Kevin Bartlett said.

The crash occurred when one of the trucks stopped on the right shoulder and was partially blocking the far right lane when the other truck crashed into the stopped tractor-trailer. The crash injured both drivers and a secondary driver in the big-rig that had stopped, CHP officials said. The two right lanes of the highway are blocked and the CHP has not said when they expect the lanes to be open again.
