DAVIS -- Two people died Thursday morning after a big-rig driver choked on food and passed out at the wheel, causing a multivehicle crash on westbound Interstate Highway 80 near the Solano-Yolo county line, according to the California Highway Patrol.

The crash was reported at 10:36 a.m. near Old Davis Road. Lanes remained closed in both directions for several hours while crews cleared the scene.

CHP officials said the driver of the big rig was eating when he choked and lost consciousness.

His truck struck two vehicles, tore through the center divide and struck a BMW head-on in the freeway's westbound lanes. The crash caused both the BMW and the big rig to catch fire.

As fire crews from Davis extracted the first body from the BMW, they discovered a second body inside the car. Neither person's identity was released Thursday afternoon; officials said at least one of the bodies was badly burned in the fire.

Eastbound lanes of Interstate 80 at the Old Davis Road exit were reopened shortly before 1:30 p.m. Westbound lanes were reopened shortly after 5 p.m., but officials planned to close some lanes overnight to better assess any damage to the roadway.
