A pedestrian with a plain white cane steps onto the road ahead. Which of the following is true?

Blind pedestrians may carry a white cane or be led by a guide dog. You must yield to blind pedestrians and you should use extreme caution around them. If they start to cross, stop and wait until they are out of danger. Sounding your horn may only startle the pedestrian or the guide dog. [1.
