What is the significance of a yellow traffic light?

A yellow traffic light is a critical warning that signifies caution for drivers. It indicates that the traffic light is about to change from green to red, prompting drivers to prepare to stop if it is safe to do so. This means that if you are approaching an intersection and see a yellow light, you should assess your speed and distance to the intersection. If you can do so safely, you should prepare to come to a stop to avoid running a red light, which carries significant safety risks as it could lead to collisions with oncoming traffic or pedestrians in the intersection.

The yellow light serves as a transitional signal, allowing drivers the opportunity to adjust their actions—whether to stop or proceed through the intersection, depending on their proximity and speed. Understanding the significance of a yellow light is essential for safe driving practices, helping to prevent accidents caused by sudden stops or red-light violations.
