Final answer:
Stop and wait patiently when a pedestrian with a guide dog or white cane is crossing at an intersection. Honking or driving close can be dangerous and disorienting to them.
Step-by-step explanation:
When you encounter a pedestrian using a guide dog or carrying a white cane at an intersection, you must understand that these are indicators of visual impairment. The correct action to take is neither to honk your horn nor to drive close to guide them. Both could be disorienting or dangerous for the pedestrian. Instead, you should exercise caution; stop if necessary and wait patiently until the person has safely crossed the intersection. This demonstrates respect for their independence and ensures their safety.
