A man died early Friday morning when his vehicle crashed and caught on fire near Interstate 680 in Alamo, according to the California Highway Patrol (CHP).
Around 2:40 a.m., officers received a report of an overturned vehicle that caught on fire the highway's southbound off-ramp to Livorna Road, according to CHP officer John Fransen.
The man, who was driving a 1999 Acura, exited the highway at a high rate of speed on the off-ramp, Fransen said.
For unknown reasons, the driver lost control of the vehicle and struck a guardrail. The vehicle then went down an embankment, struck a tree and landed on its passenger side on the off-ramp, according to Fransen.
The vehicle then burst into flames with the driver trapped inside, according to Fransen.
Fire crews extinguished the fire at 3:07 a.m., he said.
The driver was pronounced dead at the scene, Fransen said. The identity of the driver has not yet been released by the Contra Costa County coroner's office.
