The crash happened at about 7 a.m. on the southbound 215 Freeway to the 215 southbound transition road at the Moreno Valley interchange. According to the California Highway Patrol, a Toyota Sienna with seven people inside veered into the left lane, directly into the path of the box truck.

The driver of the box truck wasn’t able to avoid a collision with the van and hit its left rear, making it spin out of control. The CHP says the van entered a gore point between the transition road and the eastbound 60 Freeway then hit a collapsible guardrail.

Several of those people were children who suffered traumatic injuries, according to Riverside Fire Battalion Chief Bruce Vanderhorst. At least one child suffered a head injury, according to the CHP.

The driver of the box truck cooperated with the investigation, according to the CHP. Alcohol was not suspected to be a factor in the crash.
