One person was killed Tuesday when an SUV crashed into a stationary big rig on Interstate 5 in the far northern reaches of San Diego County, authorities reported.
The driver of the tractor-trailer had pulled to a stop on the freeway when a 54-year-old man driving a white Infinity QX4 in the #4 southbound lane plowed into it at 11:57 a.m. on the southbound side, near Aliso Creek Rest Area, according to the California Highway Patrol.
The man died of his injuries, CHP said.
California Highway Patrol officers are still investigating reasons why the driver collided into the big rig, but alcohol and/or drugs are not suspected to have been a factor in the crash.
