Garrett Morgan’s story is a powerful reminder of how one person’s vision can shape everyday life for generations. After witnessing a tragic accident between a horse-drawn carriage and an automobile, Morgan invented and patented the first three-way traffic signal in 1923, introducing the crucial “caution” phase that allowed intersections to clear safely—a forerunner of today’s yellow light. Despite coming from humble beginnings and having only an elementary education, Morgan’s ingenuity led to innovations that not only reduced accidents but also saved countless lives. His legacy lives on in every intersection we pass, proving that solutions born from necessity and empathy can have a lasting global impact.
