The combination of red and amber lights showing simultaneously means you must wait for the green light before proceeding. This signal serves as a warning that the traffic light is about to change to red, indicating that vehicles need to halt. It ensures drivers are fully prepared to stop safely, reducing the risk of accidents at intersections. This phase is crucial for maintaining traffic order and ensuring that everyone adheres to the rules governing road usage. While preparing to stop is part of understanding traffic light signals, the key implication of red and amber together is specifically the obligation to wait for the green light. Thus, a driver is expected to stop rather than take any action that would lead to driving through an intersection while it remains red.
