What does a red traffic light signify?

A red traffic light signifies that drivers must come to a complete stop and remain stopped until the light turns green. This signal is crucial for ensuring safety at intersections, as it regulates the flow of traffic and prevents accidents. Adhering to this rule helps manage vehicle movement and protects pedestrians crossing the intersection.

The nature of the red light's instruction is clear and absolute; it does not allow for any ambiguity or discretion. This means that regardless of traffic conditions or the presence of other vehicles, stopping is required.

In contrast, the other choices suggest actions that are inappropriate when faced with a red light, misinterpreting the necessary immediate response that ensures road safety. In practice, following the directive of stopping at a red light is essential for the orderly operation of traffic rules.
