What does a yellow traffic signal indicate?

A yellow traffic signal serves as a warning that the traffic light is about to change to red. This indication is crucial for drivers to exercise caution. When a driver sees a yellow light, it means they need to prepare to stop if it is safe to do so. However, if they are already too close to the intersection to stop safely, they may proceed with caution while ensuring that the intersection is clear of pedestrians and other vehicles.

This understanding emphasizes the importance of being vigilant when approaching intersections, as the yellow light serves as a transitional phase meant to promote safety and awareness. Drivers should be ready to react appropriately rather than just proceeding without consideration for their surroundings.
