How guide dogs read traffic lights

Guide dogs are specially trained dogs that can help blind people navigate and move around in their daily lives. Although guide dogs usually do not directly understand traffic light signals, they can help blind people safely navigate road traffic by following their owners' instructions and training.

The following is the general process of how a guide dog assists a blind person in crossing a traffic light:

1. Training and trust: Guide dogs and blind owners have established a close cooperative relationship and trust through professional training. Guide dogs are trained to understand commands, including recognizing signs at traffic lights.

2. Stop at traffic lights: When a blind owner approaches a traffic light, he or she will ask the guide dog to stop to ensure the perception and judgment of the traffic light status.

3. Listen to environmental sounds: Blind owners will rely on hearing and sounds in the surrounding environment to understand changes in traffic lights. For example, they can listen to the audible instructions of a traffic light or the sound of a passing car.

4. Physical commands: The blind owner uses commands and gestures to tell the guide dog to continue moving forward or stop and wait. For example, when a traffic light turns green, a blind owner signals the guide dog that it is okay to proceed.

5. Direction and safety: Guide dogs will lead the blind owner in the direction indicated by the traffic lights and ensure safe crossing of the road. They are trained to follow the rules of the road and avoid obstacles and traffic.

It should be noted that the ability of a guide dog still requires the cooperation and judgment of the blind owner. Blind owners need to remain alert at all times and supplement their judgment based on road conditions and other traffic signs to ensure safe crossing of the road. A guide dog’s training and abilities can provide additional assistance and confidence when facing various traffic situations.
