What does a red light mean?

A red light indicates that you must stop completely and remain stopped until the light turns green. This traffic signal is essential for maintaining order and safety on the roads, as it helps to control the flow of traffic at intersections. The purpose of the red light is to prevent vehicles from entering the intersection and potentially colliding with other vehicles or pedestrians who may have the right of way.

While some other responses may imply varying degrees of caution or yielding, none convey the importance of a full stop as clearly as the correct answer does. Understanding this rule is crucial for every driver's safety and for the overall functioning of traffic systems. Remember, disobeying a red light can lead to serious accidents and legal consequences, so it’s vital to recognize this signal and act accordingly.
