line of tractors driving down a street in what appears to be a European city

line of tractors driving down a street in what appears to be a European city. The day is foggy, and the street is lined with parked cars and buildings of varying architectural styles. A bike lane is visible on the left side of the road, and a pedestrian stands on the sidewalk to the right. There's a 30 km/h speed limit sign visible. The tractors are interspersed with a few white vans and one or two motorcycles and carry yellow flags. The sounds of a horn can be heard.
