What does a yellow light mean at an intersection?

A yellow light at an intersection serves as a warning that the signal will soon change to red. It indicates that drivers should prepare to stop if it is safe to do so. The purpose of the yellow light is to allow sufficient time for vehicles already approaching the intersection to make a decision to proceed with caution or to stop.

Understanding the implications of a yellow light is vital for maintaining safety on the roads. It is essential for drivers to recognize that this signal is not a cue to speed up, as doing so could lead to dangerous situations. The light does not indicate a change to green, and it certainly is not a directive to yield solely to pedestrians, as the primary focus of the yellow signal is to alert drivers regarding the impending red light. This understanding reinforces safe driving practices and decision-making at intersections.
