The Highway Patrol said the van veered onto the wrong side of the road, hitting another car head-on. The two boys were ejected from the van on impact.
The CHP says none of the children were wearing seatbelts. Their father is hospitalized with minor injuries. Four people in the other vehicle were injured, one seriously.
The CHP doesn't know what led to the crash -- but they do not believe drugs or alcohol were a factor.
