What does a red traffic light indicate?

A red traffic light indicates that drivers must come to a complete stop. This signal is crucial for maintaining traffic safety, as it prevents vehicles from entering an intersection when it is not safe to do so. The purpose of the red light is to control the flow of traffic and reduce the risk of collisions, especially at intersections where visibility may be limited.

When the light turns red, all vehicles must stop at the marked stop line or, if there is no line, before entering the intersection. This stopping requirement allows cross traffic to proceed safely and ensures that pedestrians can cross the road without the risk of oncoming vehicles.

While the other choices may suggest alternative actions, they do not align with the fundamental rule that a red traffic light clearly communicates a stop requirement.
