Two motorists were injured Monday, one seriously, in a four-vehicle pileup on Interstate 8 in Mission Valley.

The accident occurred shortly after 12:30 p.m., when a BMW that had just entered the freeway from Texas Street suddenly swerved to the left for unknown reasons, crossing all five westbound lanes, according to the California Highway Patrol.

Near the center of the interstate, the car struck a Ford F-150 pickup truck, then spun out and collided with a Toyota Previa minivan, sending it crashing into a center-divider wall, CHP public-affairs Officer Jake Sanchez said. Broken body parts from the latter vehicle hit another Toyota, damaging it.

Medics took the driver of the BMW, a 55-year-old San Diego man whose name was withheld, to Scripps Mercy Hospital for treatment of major trauma. The 50-year-old San Diego man who had been behind the wheel of the Previa was transported to the same medical center with minor injuries, Sanchez said.

The Highway Patrol received a report of a dead poodle at the site of the accident, possibly having been ejected from one of the involved vehicles, but an officer who went to the scene to look for the animal could not find it, the spokesman said.

Investigators believe that the driver of the BMW might have lost control of his car due to some type of medical emergency, according to Sanchez.
