Final answer:
When you see a pedestrian with a yellow cane, you should proceed with caution and be prepared to offer assistance if necessary, as they may be visually impaired.
Step-by-step explanation:
When you see a pedestrian holding a yellow cane, it is an indication that the person may be visually impaired or blind. The correct action to take is not to sound your horn, ignore them, or speed up and pass them quickly. Instead, you should show caution and be prepared to stop and offer assistance if it appears necessary. The yellow cane is an internationally recognized symbol of blindness or low vision, signaling drivers and others to proceed with care. If the pedestrian is attempting to cross the street or navigate through traffic, it's imperative to give them the right of way and wait patiently until they have safely crossed or no longer need assistance.
