How should you respond to a red and yellow light at a traffic signal?

The correct choice emphasizes the importance of safety and awareness at traffic signals. A red and yellow light specifically serves as a warning that the traffic signal is about to turn red. This alert is designed to give drivers an opportunity to prepare to stop safely, ensuring they are not caught off guard when the light changes completely to red.

By stopping when you see a red and yellow light, you are following the rules of the road that prioritize the safety of all road users, including pedestrians who may be waiting to cross. This action also helps prevent accidents that could occur if drivers were to accelerate or proceed without proper caution when approaching an intersection that is about to change its signal.

In contrast, actions such as accelerating to get through the intersection or waiting for a green light do not align with the intended purpose of the red and yellow light. These actions could potentially lead to dangerous situations and violate traffic regulations designed to maintain order and safety on the roads.
