Who has a severe visual handicap?

Your answer is correct. The man in the image has a severe visual handicap, as indicated by his white cane. In German traffic rules, a white cane is a clear sign that a pedestrian is visually impaired or blind. Drivers must exercise special caution and give priority to visually impaired pedestrians, as they might not be able to notice approaching vehicles or judge their speed well. Recognizing this symbol helps prevent accidents and ensures safe passage for people with severe visual disabilities.
