A D.C. Ducks tour boat was involved in a crash with a minivan at New York and Montana avenues in Northeast D.C. Tuesday evening. Three senior citizens in the minivan were taken to area hospitals by ambulance with non-life-threatening injuries. The D.C. Ducks Amphibious Tours vehicle is both a boat and a bus, and it was on its way back to a depot when it collided with a Toyota minivan, causing the minivan to overturn. The three occupants of the minivan were trapped.
