What does a yellow traffic light indicate?

A yellow traffic light serves as a warning to drivers that the light is about to change to red. This indicates that you should prepare to stop if it is safe to do so. The purpose of the yellow light is to provide a clear signal to drivers that they need to be mindful of the upcoming change and take appropriate action.

In practical terms, when you see a yellow light, it is essential to assess your speed and distance from the intersection. If you are too close to safely stop, you may continue through the intersection with caution. However, the primary directive of the yellow light is to prompt drivers to be ready to halt their vehicles. This helps maintain smooth traffic flow and enhances safety by preventing sudden stops that could lead to rear-end collisions.

Other options might suggest behaviors that are either unsafe or against traffic laws; for example, speeding up could lead to dangerous situations, while the idea that one can proceed in any direction or that it is safe to turn is misleading given the potential for immediate traffic changes. Understanding the function of a yellow light reinforces safe driving habits and compliance with traffic signals.
