What action should a driver take when approaching a yellow traffic light?

When approaching a yellow traffic light, the appropriate action for a driver to take is to prepare to stop. A yellow light indicates that the signal is about to turn red, and it serves as a warning to drivers that they must make a decision about their approach. This signal is intended to give drivers adequate time to slow down and come to a stop safely, rather than encouraging them to accelerate or maintain their speed.

Understanding the function of a yellow light is important for safety and traffic flow. It helps to prevent accidents that could occur if drivers attempt to rush through an intersection after the light has changed to red. Therefore, preparing to stop is the correct response because it enhances the driver's ability to react timely and appropriately, reducing the risk of encountering potential hazards as they navigate the intersection.
