How can a driver identify a blind pedestrian?

A driver can identify a blind pedestrian by the presence of a white cane with a red tip, which is a recognized symbol indicating that the person is visually impaired. This specific color combination helps to alert drivers and others in the vicinity that the pedestrian may have limited visibility and requires extra caution. The white cane is a tool used by many visually impaired individuals to navigate their surroundings safely, and the red tip provides additional recognition that the person may have visual impairments.

The other options do not provide a reliable or universally recognized way to identify a blind pedestrian. For example, while guide dogs are commonly associated with visually impaired individuals, not all blind or visually impaired people use them. Additionally, clothing color or styles, such as black clothing, does not signify blindness and could lead to misunderstandings about a person's ability. Slow walking pace can occur for a variety of reasons unrelated to visual impairment, making it an unreliable indicator. Therefore, the white cane with a red tip is the most significant and recognizable symbol used to identify a blind pedestrian.
