SAN JOAQUIN COUNTY (CBS13) – Authorities say they suspect DUI was a factor in a deadly crash that has kept Highway 4 west of Stockton closed for most of the day.
The crash happened just before 8 a.m. on the stretch road next to the river at S. Tracy Boulevard.
According to California Highway Patrol, a semi-truck cross the double yellow lines on Highway 4 and crashed head-on into an SUV heading the opposite direction. The semi then kept on going, sideswiping a minivan, before it finally crashed off the road.
