If a pedestrian has a white stick with a red band, what does this indicate?

Answer: D — They are deaf and blind

This indicates that they have both a visual and auditory impairment. Option A is incorrect because a fully blind person would typically have a completely white stick. Option B is incorrect because a partially sighted person may have a white stick, but it would not have a red band. Option C is incorrect because the red band specifically indicates that they have a dual sensory impairment. It is important to be aware of this symbol and give extra assistance to these individuals when crossing the road or navigating their surroundings.
