CHP says one person was killed Sunday when his vehicle smashed into a barricade at the Chuckwalla Valley Raceway in Desert Center.
The crash happened about 10:30 a.m. at the raceway about 55 miles east of Indio.
The CHP say only one car was involved. The driver died at the scene, and a passenger, who was initially trapped in the vehicle, was airlifted to an area hospital with major injuries.
The raceway was closed after the incident.
It is a privately-owned driving academy and event center several miles north of Interstate 10 on state Route 177.
