How a guide dog passes a traffic light, first of all, you need to understand how a guide dog works. A guide dog is a specially trained dog breed whose main task is to guide a blind or visually impaired person in their daily activities. During the guidance process, guide dogs will perceive their surroundings through their senses such as smell and hearing, and guide the blind or visually impaired through specific behaviors and reactions.
For traffic lights, guide dogs usually do not see the color of the red or green lights directly, but instead perceive changes in traffic signals through their sense of hearing and smell. During training, guide dogs learn to recognize the sounds and smells of vehicles and pedestrians, as well as the sounds and smells of traffic signals. When guide dogs hear the sound of a vehicle or pedestrian or smell a related scent, they guide the blind or visually impaired person through specific behaviors.
Specifically, when guide dogs hear a vehicle or pedestrian or smell a related scent, they stop and guide the blind or visually impaired person to stop. The guide dog then perceives changes in traffic signals through smell and hearing. When the traffic signal turns green, a guide dog will guide the blind or visually impaired person to move forward; When the traffic signal turns red, a guide dog will guide the blind or visually impaired person to wait.
In addition, guide dogs perceive changes in their surroundings in other ways. For example, when guide dogs hear the sound of an approaching vehicle, they will guide the blind or visually impaired person to get out of the way; When guide dogs smell a dangerous odor, they guide the blind or visually impaired away from the danger zone.
In conclusion, guide dogs perceive changes in their surroundings through their sense of hearing and smell, and guide blind or visually impaired people through specific behaviors. When passing through traffic lights, guide dogs guide blind or visually impaired people by perceiving the sounds and smells of traffic signals. While guide dogs cannot directly see the color of a red or green light, they can sense changes in traffic signals in other ways to ensure the safety and convenience of people who are blind or visually impaired.
It is important to note that while guide dogs are a very good aid, they are not a complete replacement for human vision and judgment. Therefore, when passing through traffic intersections such as traffic lights, blind or visually impaired people still need to stay alert and pay attention to changes in their surroundings to ensure their safety. At the same time, all sectors of society should also strengthen their attention and support for the blind or visually impaired, and provide them with more convenience and assistance.
