Three people were injured in a large traffic collision at 14th Street and Constitution Avenue NW this morning. The intersection has since reopened, but the crash, which involved a D.C. firetruck along with two civilian vehicles, caused major traffic delays throughout the area for well over an hour.

D.C. Fire/EMS spokesperson Pete Piringer said the firetruck was on its way to George Washington University Hospital when it got into a crash with the two other vehicles.

No firefighters were injured in the collision, but three individuals were transported to a nearby hospital, one of them in serious condition, Piringer said.
