A multi-vehicle crash has set at least one vehicle on fire on the southbound lanes of Interstate 15 in Rancho Penasquitos, prompting the California Highway Patrol to issue a Sig Alert for the area.
CHP officials believe the chain-reaction collisions were originally caused by some trash cans on the freeway around 3:50 p.m. Thursday.
Three lanes of I-15 were blocked by the crash, which was near Poway Road. One car became fully engulfed in flames, and one person was taken to the UC San Diego Burn Unit for injuries.
The extent of the injuries are unknown.
