The three separate wrong-way incidents were reported in Oakland, San Mateo County, and the North Bay, resulting in the deaths of two people and hospitalizations of five.

In East Oakland around 7 a.m. Sunday morning, a wrong-way Ford F-150 pickup truck driver heading east on westbound Interstate 580 near the Seminary Avenue off-ramp crashed into a city-owned truck, as ABC7 reported. CHP was reportedly called by witnesses who said that the Ford F-150 pickup truck, going the wrong direction, seemed to be intentionally trying to run head-on into other vehicles.

The driver of the truck eventually struck a white Ford F-250 pickup from Oakland's Park and Tree Services, KTVU reported, prompting a road closure for about an hour and a half. The driver of the F-150 was hospitalized with major injuries, and the driver of the city vehicle also suffered minor injuries, according to ABC7. Police are still investigating whether or not drugs or alcohol were involved
