What is the meaning of a yellow traffic light?

A yellow traffic light signals to drivers that the light is about to change to red, indicating that they should prepare to stop. This warning is crucial because it gives drivers the opportunity to assess their speed and distance from the intersection before the signal changes.

In this scenario, drivers approaching a yellow light should be cautious and determine whether they can safely stop without rushing or stopping abruptly. The intent of the yellow light is to enhance traffic safety by making drivers alert to the upcoming change in traffic control. Recognizing a yellow light as a cue to prepare to stop helps prevent accidents that can occur when drivers rush through an intersection after the light has changed.

The other options would compromise safety; for instance, coming to a complete stop may not always be appropriate depending on the situation, while speeding up can lead to dangerous outcomes. Thus, understanding the yellow light as a prompt to prepare to stop is vital for maintaining safe driving practices.
