What does a yellow traffic light signify?

A yellow traffic light signifies that the light is about to change to red, which means drivers need to prepare to stop. This signal warns drivers to clear the intersection safely if they are already in it or to stop if they can do so safely before entering. The purpose of the yellow light is to give drivers a moment to react and decide whether they should stop or proceed, promoting safe driving practices as the traffic signal changes.

Responding to yellow lights appropriately helps in preventing accidents that could occur if vehicles attempt to enter intersections when the light has turned red. Understanding this rule is crucial for maintaining traffic flow and safety on the roads.
