MALIBU – A gravel truck plowed through a red light Wednesday and struck two cars, killing two people and injuring an off-duty Los Angeles County firefighter, authorities said. The big-rig was traveling on Kanan Dume Road, which is normally off-limits to trucks, when the driver apparently lost control on a downhill grade and tore through the red light at Pacific Coast Highway at about 70 mph, Los Angeles County sheriff’s Sgt. Philip Brooks said. The truck hit a Mercedes and instantly killed its driver, then struck a sport utility vehicle driven by the firefighter. The truck then slammed into a hillside, killing the driver. The identities of the victims were not immediately released.

Gregory Hill said. The firefighter’s ankle was broken and he was trapped in his car until he was pulled free, Brooks said. He was taken to a hospital. Brooks said many truck drivers have been using Kanan Dume in the past several days because their normal route was closed due to fire. The Canyon Fire destroyed six homes, two businesses and a church, blackened 4,500 acres and injured four people. At the time of the crash, around 10 a.m., the fire was 85 percent contained and Pacific Coast Highway had been reopened for only a short time. Authorities opened the route at about 7 p.m. Wednesday, just after Los Angeles County Fire officials said the Canyon Fire was fully contained.
