Garrett Morgan's greatest achievement was the invention of the three-position traffic signal in 1923, which significantly improved road safety by allowing for a cautionary yellow light between stop and go signals. He was also known for developing a safety hood and smoke protector, an early version of the gas mask, which proved invaluable during emergencies, including fires. Morgan's innovations not only showcased his ingenuity but also contributed to advancements in public safety. His work laid the groundwork for modern traffic control systems and firefighting equipment.
