Why Traffic Lights Are Red, Yellow & Green (Shocking Truth)

Have you ever wondered why traffic lights are red, yellow, and green? It’s not random—and it’s not just tradition. The real reason behind traffic signal colors involves deadly railroad accidents, the physics of light wavelengths, and a critical safety breakthrough that changed modern transportation forever. In this video, we uncover the surprising history of traffic lights, from 19th-century train disasters to the invention of the first electric traffic signal in Detroit. You’ll learn how red light travels farther through fog and rain, why green replaced white as the “go” signal, and how the yellow light prevents millions of rear-end collisions every year. This is the hidden science of traffic signals, explained through physics, human biology, and real historical events. The next time you stop at a red light, you’ll understand the powerful science keeping you alive.
