A small plane on a training flight crashed into a car on Interstate 80 on Saturday. The car's driver was slightly hurt, but the student pilot and instructor were uninjured, police said.

The two-seat Cessna 152, which was traveling eastward, came down in the eastbound lanes. It was unclear whether the pilot was attempting an emergency landing, said California Highway Patrol spokeswoman Sgt. Pat Tracy.The plane's origin was the Oakland airport, and the student and instructor are members of a flying club at the University of California at Berkeley, Tracy said.

The car's driver was treated for minor injuries at a hospital, Tracy said. She said the two people aboard the plane declined treatment.
