The CHP received reports of a solo vehicle spinout on southbound Highway 101 at Sierra Point Parkway at around 3:35 a.m., Officer Scott Cakebread said.
The driver of a Honda apparently lost control of the vehicle while driving south and drifted off the roadway, overturning on the right hand shoulder.
The driver was killed in the crash and pronounced dead at the scene.
It does not appear that any other vehicles were involved, Cakebread said.
There were no lane closures on Highway 101 caused by the crash or the ongoing investigation.
