Your vehicle has left a considerable amount of dirt on the carriageway, causing a risk to road traffic. What do you have to do?

You have selected both correct answers. If your vehicle leaves dirt on the road that creates a hazard, German traffic rules require you to clean up the dirt immediately to prevent accidents and maintain safety. Additionally, until the area is clean, you must clearly mark or warn about the danger, so other road users can react appropriately. These measures help prevent accidents and fulfill your duty to ensure road safety. Ignoring the hazard, even if it seems obvious to others, is not allowed—you must always act to remove or warn about such dangers. This is both a legal obligation and an important part of being a responsible driver.
