What does a yellow traffic light indicate?

A yellow traffic light primarily indicates that the light will soon turn red, signaling drivers to prepare to stop. This warning allows drivers to clear the intersection safely and adjust their actions accordingly. When a yellow light is illuminated, it signifies that the signal is transitioning, and thus, it is essential for vehicles to either proceed with caution if they are already in the intersection or come to a stop if it is safe to do so.

This reinforces safe driving practices and helps prevent accidents by ensuring that drivers do not enter an intersection blindly or with the expectation that they can keep going as if nothing is changing. Understanding the meaning of a yellow light is crucial for maintaining traffic flow and safety on the roads.
