Who has a severe visual handicap?

Your answer is correct. The man with the white cane has a severe visual handicap. In German traffic rules, visually impaired pedestrians are recognized by their white cane, sometimes accompanied by a guide dog or a special armband. Drivers must be particularly cautious and give right of way to these individuals because they have limited or no ability to see oncoming traffic. Recognizing and respecting this protects vulnerable road users and prevents accidents. The child and the woman do not have any visible indication of visual impairment, so the man is the one with the severe visual handicap in this scenario.
