Three children were evacuated from a school bus on the 14 Freeway near Newhall Thursday morning after it broke down and began smoking, CHP said.
The bus was first reported as being on fire near Soledad Canyon Road on the northbound side of the freeway just before 8 a.m.
Los Angeles County Fire Department units responded to the report, but found the bus was only smoking, according to CHP.
