A large power shovel picks up the coal and loads it into a dump truck. The loaded truck drives down a dirt road. View from truck cab of driver at the wheel of the truck. The loaded truck proceeds downward on left side of road, far from road edge, while empty trucks keep to their own left coming up, nearer the road edge.
