A white semi-truck with a yellow generator unit attached to its trailer is parked on an asphalt surface. Two individuals are near the generator unit. One individual, wearing an orange safety vest, is operating a piece of equipment connected to the generator, which is emitting a stream of black material onto the ground. Another individual, also wearing an orange safety vest, is observing. The scene is outdoors, with trees, a multi-story building, and small storefronts in the background. Several cars are parked nearby. The ground appears to have some patches of wetness or dark material.
