What does a yellow traffic light indicate?

A yellow traffic light serves as an important warning signal indicating that the light is about to change to red. When drivers see a yellow light, it means they should slow down and prepare to stop, but it does not require them to stop immediately if they are already too close to the intersection to do so safely. This is why proceeding with caution is the correct response; drivers should be aware that the light is changing and be prepared for the possibility of needing to stop if the light turns red. The emphasis here is on careful observation of surrounding traffic and road conditions, as well as being ready to respond appropriately as the situation evolves.

It is essential for drivers to remain alert and make decisions that are safe and compliant with traffic laws given the transition indicated by a yellow light.
