At 1156hrs, TF221 was dispatched to an MVA at the intersection of North Locust Avenue and North Maple Avenue. Central Communications had advised on dispatch there was one vehicle overturned and there was a report of a victim trapped inside one of the vehicles. Units arrived and found a small compact vs. a full sized van, with the van on its side and the occupant still inside. The patient was able to self extricate with minor injuries from the vehicle with some assitance from responders on scene who removed the windshield of the van.
