A dog wearing a yellow or burgundy coat indicates the presence of a deaf pedestrian. This specific color coding is a recognized way to alert others that the individual accompanied by the dog may not be able to hear surrounding sounds, which could include traffic or other potential hazards. Therefore, drivers and pedestrians should exercise increased caution and awareness when encountering a dog with this type of coat, understanding that they may need to adjust their behavior to ensure the safety of the person with the hearing impairment. The other options do not accurately represent the meaning of the coat colors. For instance, while service animals do perform crucial roles, the specific colors in question are explicitly used to indicate the presence of a deaf individual rather than a general service animal or any other conditions such as traffic or road conditions.
