What action should be taken when encountering a red traffic light?

When you encounter a red traffic light, the appropriate action is to stop and wait for it to turn green. This is critical for maintaining traffic safety and following the rules of the road. A red light signals that vehicles must come to a complete stop at the designated stop line or before entering the intersection. This allows for the safe passage of vehicles, pedestrians, and cyclists who may have the right of way.

The importance of stopping at a red light cannot be overstated, as running a red light poses significant risks, not only to the driver but also to others on the road. It's a fundamental rule intended to prevent accidents and chaos at intersections.

In contrast, other options suggest actions that could lead to dangerous situations. Speeding through an intersection without assessing the safety of the area can lead to collisions, while proceeding with caution or following another vehicle can still result in accidents if the driver is not fully attentive to the traffic signals. Therefore, stopping at a red light is the safe and legally mandated choice.
