A D.C. fire truck and a Chevrolet Camaro collided at a Southeast Washington intersection Wednesday afternoon, trapping a civilian driver in the wreckage and injuring three firefighters, according to authorities.

The accident occurred about noon at 53rd Street and Drake Place, in the Marshall Heights neighborhood. A fire department spokesman said the engine was returning from a call when the accident occurred and was not on an emergency run.

Details of what happened were not immediately available, but police and fire officials quoted witnesses as saying the Camaro ran into Engine 30, which along with Truck 17 is based at a station in Northeast Washington. The precise cause has not yet been determined.

The driver of the Camaro suffered serious injuries, Tim Wilson, a fire department spokesman, said, though the extent were not immediately known. Wilson said it took firefighters about 30 minutes to extricate the driver.

Injuries to the firefighters appear minor; they were taken to a medical clinic and did not require hospital treatment, Wilson said.
