What indicates that a pedestrian may be blind?

A person using a white cane is universally recognized as a signal that they may be blind or have significant visual impairment. The white cane serves multiple purposes: it helps individuals navigate their surroundings, it provides information about the environment by detecting obstacles, and it also alerts others to their visual impairment. This tool is not only a practical device but also a symbol of increased awareness about blind and visually impaired individuals, reinforcing the need for drivers and pedestrians to exercise caution and understanding in their interactions.

While sunglasses may sometimes be worn by individuals with visual impairments, they are not a definitive indicator of blindness since many people wear sunglasses for various reasons unrelated to sight. Having a companion might provide assistance, but it doesn’t specifically denote blindness, as anyone could have a friend or family member with them regardless of their sight ability. Rapid walking could suggest urgency or confidence but doesn't relate to visual impairment. Therefore, the use of a white cane is the most reliable indicator that a pedestrian may be blind.
