What does a red traffic light mean?

A red traffic light indicates that drivers must come to a complete stop at the designated stop line, crosswalk, or intersection before proceeding. This signal is crucial for maintaining safety on the road, as it helps manage the flow of traffic and signals to drivers that they do not have the right of way. Stopping at a red light allows other vehicles or pedestrians to move safely through the intersection. Understanding the meaning of a red light is fundamental for all drivers to ensure compliance with traffic laws and to prevent accidents. This is why stopping is the required action when faced with a red light. Other potential meanings, such as proceeding with caution or signaling to go, could lead to unsafe situations and are not consistent with the traffic regulations established for road safety.
