Trooper Christopher Kay says it appears one bus rear-ended another bus and the other two vehicles sustained minor damage in the accident in Parsippany.
Kay says the buses were taking 9- and 10-year-olds from Lindenmere Sports Camp in Tannersville, Pa., to Six Flags Great Adventure amusement park in Jackson, N.J. He says there were more than 100 passengers on the four buses.
Kay says none of the injuries was life-threatening. The trooper says the children complained of pain or simple cuts and bruises.
The cause of the accident is under investigation.
