CAR FIRE-- A Pontiac Bonneville caught fire Tuesday afternoon alongside Interstate 15 in Orem, causing heaving smoke that led to the closure of the freeway's southbound lanes. About 3:17 p.m., the driver of the car pulled it over approximately a quarter of a mile south of the University Parkway exit. The occupants got out of the vehicle. When firefighters arrived, the car was fully engulfed in flames. The southbound lanes of I-15 were closed about 10 to 15 minutes.
