What does a yellow traffic light indicate?

A yellow traffic light indicates that drivers should prepare to stop. This signal serves as a warning that the light is about to change to red, meaning vehicular traffic should prepare to come to a halt. The purpose of this warning is to give drivers sufficient time to stop safely before the light turns red, preventing dangerous situations and ensuring orderly traffic flow. It is crucial to recognize that the yellow light does not mean to speed up or proceed as usual, but instead emphasizes the need to slow down and stop when it is safe to do so.
