22-year-old woman, 2-year-old and 8-month-old seriously injured, transported to hospital, after their vehicle leaves the I-805 roadway in San Diego and overturns.

A woman and two children were transported to hospitals Monday night following a rollover crash on Interstate 805 north near El Cajon Boulevard, authorities said.

The crash was reported about 7:30 p.m., a California Highway Patrol dispatcher said.

Two patients were taken to Rady Children's Hospital, a San Diego fire dispatcher said. Another was transported to Sharp Memorial Hospital.

The vehicle overturned on the right-hand shoulder and ended up on the embankment, and a man was trying to get people out of the vehicle, the CHP website said.

According to emergency radio traffic, the patients were an eight-month-old, a 2-year-old and a 22-year-old woman.
