CHICAGO (CBS) —  Ten children and seven adults were taken to the hospital, after three school buses taking them on a YMCA field trip were involved in a chain reaction crash with a dump truck loaded with landscaping material Thursday morning in north suburban Libertyville.

The Lake County Sheriff’s Office said, around 10:45 a.m., the school buses were headed west on Route 137 near River Road, when they slowed down for traffic in front of them, and a Mack dump truck was unable to stop before rear-ending one of the buses.

The buses were carrying 144 children and staff from North Suburban YMCA’s summer day camp, for a field trip.

Paramedics from the Libertyville Fire Department and other area fire departments evaluated all 144 people on the buses, and 10 children and seven adults who suffered minor injuries were taken to Advocate Condell Medical Center.
