As Company 17 was clearing an accident in 28s area, they were dispatched to East Village and Harbor Tree for the report of one overturned. A717, RS717, C717D, and PE708 arrived on scene to find a vehicle that had struck a tree, overturned, and pinned an occupant's hand under the vehicle. The squad crew quickly stabilized the vehicle and raised it off the patient's hand. Once freed they were extricated and transported to a local hospital. The road had been closed for a short period but is now open.
