How does a guide dog know when it would be safe for the handler to cross the road?

Guide dogs are trained to recognize specific cues for safe road crossing, including traffic patterns, sounds, and visual signals. They can sense when there are no vehicles approaching and may wait for a command from their handler before proceeding. Additionally, guide dogs are taught to respond to their handler's cues and instincts, allowing them to make safe decisions together. Their training emphasizes teamwork, ensuring the handler's safety while navigating crossings.
