What does a red traffic light indicate?

A red traffic light indicates that drivers must come to a complete stop before the intersection or crosswalk. This signal is crucial for promoting safety by controlling the flow of traffic and ensuring that vehicles do not enter intersections when it is unsafe. When other vehicles or pedestrians have the right of way, it is essential for drivers to stop and wait until the traffic light turns green, signaling that it is safe to proceed. Understanding the significance of a red light is fundamental for maintaining traffic safety and preventing accidents at intersections.
