Traffic Light Color Basics
Traffic lights use a standardized color scheme to communicate clear and concise instructions to drivers and pedestrians. The most common colors used are red, yellow, and green.
Red signifies “stop,” yellow indicates “caution,” and green means “go.” These colors were chosen for their high visibility and distinctness, ensuring they can be easily recognized and understood by individuals from diverse backgrounds and abilities.
Historical Evolution of Traffic Light Colors
The first traffic lights were installed in London in 1868 and used gas lamps to display red and green lights. In 1912, electric traffic lights were introduced in Salt Lake City, Utah, featuring the now-familiar red, yellow, and green sequence.
The standardization of traffic light colors occurred in the early 20th century, with the National Conference on Street and Highway Safety establishing the current color scheme in 1920. This standardization aimed to improve traffic safety and consistency across the United States.
Country Variations
While the red-yellow-green sequence is widely used, some countries have adopted different color combinations for their traffic lights. For example, in Japan, blue is used instead of green to indicate “go.”
These variations reflect cultural and historical differences, as well as the specific needs and conditions of each country’s traffic system.
