Around 5:24 a.m., a sedan collided with two big rigs on Highway 238 just south of the Hesperian Boulevard off-ramp.
The crash pinned the sedan underneath one of the big rigs, and caused one of the big rigs to start leaking fuel, according to the CHP.
The right lane near the crash is blocked, and a left lane on-ramp to northbound interstate Highway 880 near the crash has been shut down.
