Yellow, or amber, serves as a transitional caution, providing a clear buffer between the commands to stop and go. Traffic engineering aims to time this phase appropriately, known as the yellow duration, to balance safe stopping distances with the need to keep traffic flowing smoothly.
This specific arrangement was adopted from railway signaling systems, where red meant stop and green meant proceed, with white later being used for caution before being replaced by yellow due to issues with confusion and fading glass signals. Global Standards and Consistency One of the remarkable aspects of traffic light colors is their near-universal consistency.
