The California Highway Patrol is continuing to investigate a fiery crash that killed four people and shut down part of U.S. Highway 395 Friday night about 30 miles south of the California-Nevada line.
The patrol said Monday two vehicles collided head-on at about 5:15 p.m. about 4 miles south of Bridgeport, California.
For unknown reasons, a northbound Subaru Impreza crossed the center line and hit a southbound Chevrolet Silverado pickup pulling a fifth-wheel trailer.
The pickup and the trailer overturned and the pickup caught fire, blocking both the northbound and southbound lanes.
Both drivers and a passenger in each vehicle were killed.
The patrol says all the victims appeared to have been wearing seatbelts. Neither drugs nor alcohol appear to have played a role in the crash but the cause remains under investigation.
