Where must you particularly reckon with dirt on the roadway and therefore danger of skidding?

The selected combination is correct because both locations, near construction sites and at junctions with farm tracks, are areas where dirt and debris can accumulate on the roadway. This can significantly increase the risk of skidding, making it essential for drivers to exercise caution.

Construction sites often involve heavy machinery and hauling activities, which can bring dirt onto the road. Likewise, at junctions with farm tracks, vehicles frequently drive on and off these paths, potentially dragging mud onto the roadway.

Understanding these hazards is part of safe driving practices highlighted in German traffic regulations, which emphasize the need for heightened awareness in such environments. This knowledge helps prevent accidents and ensures a safer driving experience.
