What is the meaning of a yellow traffic light?

A yellow traffic light signals that the light is about to change to red, indicating that drivers should prepare to stop if it is safe to do so. This warning allows enough time for drivers to react, ensuring they have the opportunity to slow down and stop safely before the light turns red. It serves as a transitional signal, conveying the need for caution and alertness as one approaches the intersection.

While some drivers might think to accelerate or proceed quickly through an intersection when they see a yellow light, doing so can lead to unsafe situations, including running a red light. It is crucial for drivers to understand that the primary purpose of a yellow light is to prepare them for a stop, thus minimizing the risk of accidents at the intersection.
