Officials say wearing a seat belt is the easiest and quickest way to survive a crash. Fifty-six people were killed on California roadways over the 2004 Thanksgiving weekend. Within the CHP’s jurisdiction, of the 39 vehicle occupants killed, 15 were not wearing seat belts. Two people died last Thanksgiving weekend on Antelope Valley highways and roads. A 26-year-old Littlerock woman died the night before Thanksgiving 2004 when her car collided head-on with a big rig on Highway 138, and a 41-year-old Littlerock woman died the following Saturday when her sport utility vehicle hit a tree blown down by wind onto Avenue K east of Lancaster. Meanwhile, the California Department of Transportation warns travelers to expect heavy traffic during peak periods on Interstate 5 north of Santa Clarita at Templin Highway. Crews continue work to stabilize a mountainside that caused heavy damage to the freeway during rains last winter. Three northbound lanes and four southbound lanes remain open. Caltrans officials suggest using The Old Road, which parallels the freeway through the Santa Clarita Valley, as an alternate.
