Seventeen people, including 14 children, were injured today in a multi-vehicle collision, an ambulance service said.
The crash, which involved two coaches and a car, happened on the A449 near Worcester at 10.10am.
West Midlands Ambulance Service said the casualties sustained only minor injures, describing them as "walking wounded".
A WMAS spokesman said: "Two coaches, taking children from Gloucestershire to the West Midlands Safari Park and a car were involved in a collision in the roadworks area of the A449 near Claines Island.
"Fourteen children and two adults from the coaches and the woman driver of the car all had neck pain and were complaining of feeling unwell. They were all walking wounded casualties who were taken to a nearby campsite away from the road to be assessed and treated.
"They were all found to have minor injuries and were then taken Worcestershire Royal Hospital. Because of the number of casualties, a patient transport services ambulance was called in to help transport some of the patients to hospital."
A spokeswoman for Gloucestershire County Council said five coachloads of children from the mixed secondary school had been heading to the safari park when two were involved in the accident. Pupils on the other three coaches were taken back to school.
