What does a yellow traffic light signal mean?

A yellow traffic light signal serves as a warning that the light is about to change to red. This signal indicates that drivers should prepare to stop if it is safe to do so. The purpose of the yellow light is to alert drivers to the impending change, allowing them time to slow down and stop safely before the light turns red.

This precaution helps prevent accidents and ensures that vehicles do not enter the intersection against a red light. Understanding the meaning of a yellow light is crucial for maintaining traffic flow and safety, as it encourages drivers to be attentive and responsive to changing traffic conditions.

While some may think to speed up to clear the intersection, this could lead to unsafe situations, particularly if others are also trying to navigate the changes. Stopping immediately, regardless of your proximity to the light, can also be hazardous as it may cause a sudden stop that could lead to rear-end collisions. Therefore, it's important to assess the situation and respond appropriately, keeping in mind that caution is key when approaching a yellow light.
