The colors of the traffic lights you see every day were not chosen randomly. There are specific scientific and safety reasons behind each of them:
Red means danger and stop. Red is best seen from a distance, so it is the most effective color to warn drivers and pedestrians.
Yellow means be careful. This color immediately catches the eye and reminds you to be ready for the next action.
Green means safe to proceed. Since the human visual system is sensitive to green, this color is suitable for allowing traffic.
These three colors in traffic lights are a standard accepted worldwide and are essential for ensuring road safety. 🌍🚗
